The PosiTector SmartLink measurement solution consists of a PosiTector App, PosiTector SmartLink device and compatible PosiTector probe. In addition to the PosiTector DPM, compatible probes include the PosiTector SPG/RTR-H (surface profile) and 6000 (coating thickness).

Why is Measurement Important?
For industrial painters, the primary reason for measuring climatic conditions is to avoid rework and the premature failure of protective coatings. Recommendations and requirements are covered under various internationally recognized standards.

Temperature - It is important to measure both surface and air temperatures as they are often different. Application at incorrect temperatures can cause defects including: blistering, pinholing, cratering, dry spray & mud cracking. By measuring surface temperature it is possible to avoid potential application problems if air or surface temperatures become too hot or too cold for satisfactory film formation. Surface and air temperatures directly affect the rate of cure of the applied coating or lining system and are major factors in the formation of surface moisture or dew. ASTM D3276 Standard Guide for Painting Inspectors (Metal Substrates) states that the minimum air/surface temperature is usually 5°C (40°F).

Relative Humidity - the amount of moisture in the air expressed as a percent of overall volume. High relative humidity can retard the rate of solvent evaporation. For this reason, the maximum relative humidity at which coatings or linings can be applied and cured is generally set at 85%. This can be set as an alarm in the Advanced model.

Dew Point Temperature - the temperature at which moisture will begin to form on a surface. The dew point temperature is a function of air temperature and the relative humidity. (see ISO 8502-4 Annex A). It is the temperature to which a volume of air must be cooled in order to reach saturation. A number of major standards organizations call for careful dew point control. Moisture on a freshly blasted steel substrate will cause the steel to rust. If a thin, invisible film of moisture is trapped between the applied coating and the substrate, the system will likely fail prematurely. To ensure that dew point problems do not exist, ISO 8502-4 and SSPC guidelines state that the surface temperature must be a minimum of 3°C or 5°F above the dew point during the 3 critical phases of coating preparation, application, and cure.

Calibration
Calibration is the controlled and documented process of measuring traceable calibration standards and verifying that the results are within the stated accuracy of the Gage. Calibrations are typically performed by the Gage manufacturer or by a certified calibration laboratory in a controlled environment using a documented process. The PosiTector DPM is shipped with a Certificate of Calibration showing traceability to a national standard. For organizations with re-certification requirements, the PosiTector DPM may be returned at regular intervals for calibration. DeFelsko recommends that our customers establish Gage calibration intervals based upon their own experience and work environment. Based on our product knowledge, data and customer feedback, a one year calibration interval from either the date of calibration, date of purchase, or date of receipt is a typical starting point.

Written Calibration Procedures are available online at no charge. http://www.defelsko.com/quality/calibration_procedures.htm

Operation Overview

The PosiTector SmartLink powers-up when the LED button is pressed. To preserve battery life, the PosiTector SmartLink powers-down after 5 minutes of no activity. Alternatively, press and hold the LED button until it turns red and shuts off (approximately 5 seconds). All probe settings and calibration adjustments are retained within the PosiTector SmartLink, stored measurement data is retained within the smart device (cell phone, tablet).

1. Wirelessly Connect the PosiTector probe to the smart device using the PosiTector App.

2. Remove the protective rubber cap from the surface temperature sensor.

Measure

A typical screen consists of RH, Ta, Ts, Td, Ts-Td and Tw readings. This group of readings is referred to as a dataset.

RH - The relative humidity sensor is located inside the vented area of the probe housing. The sensor may require a longer period to stabilize in the event of extreme humidity changes.

Ta - The air temperature sensor is located inside the vented area of the probe housing. (Also known as Dry Bulb temperature)

Ts - A surface temperature thermocouple is located on the tip of the probe (built-in probe model). It is spring loaded and designed to quickly self-align on a surface. Press it against a surface and allow a few seconds for the value to stabilze. Do not drag the sensor over the surface, Wet the surface for a faster response. Cover with the included protective plastic cap when not in use.

For surface temperature measurement on steel over an extended of time, consider using a PosiTector Standard or Advanced model with optional Magnetic Surface Temperature probe. Both models feature Auto Log mode for monitoring climatic parameter over extended periods of time. Learn more: www.defelsko.com/dpm/

Td -The dew point temperature is a function of air temperature and relative humidity (see ISO 8502-4 Annex A). It is the temperature to which a volume of air must be cooled in order to reach saturation.

Ts -Td - The surface minus dew point temperature is important in judging the risk of condensation, or dew, forming on a surface. For example, ISO 8502-4 recommends that, unless otherwise agreed, the temperature of a steel surface generally should be at least 3°C (5°F) above the dew point when paints are applied.

Tw - The wet bulb temperature is the temperature of adiabatic saturation. This is the temperature indicated by a moistened thermometer bulb exposed to air flow.

The wet bulb temperature is calculated from Ta and RH using an air pressure of 1.0 atmospheres (1013 mbar). It approximates the temperature indicated by a moistened thermometer bulb exposed to airflow. Variations of Tw at other pressures could be greater than +1°C (+2°F).


The PosiTector DPM sensors may require a period of time before the above climatic readings stabilize. This is most noticeable when the instrument is relocated from one extreme environment to another (i.e. from a warm location to a cold location).  A period of up to 30 minutes should provide adequate time for stabilization.

Smart Trend Indicators
Identify rising, falling or stable readings. The instrument compares each measurement with recent values to provide the current direction of change.

While the absence of an arrow does not necessarily signify stability, it can be taken to mean that particular reading is undergoing little or no change. Slow changes could therefore occur without being noted by an indicator arrow.

PosiTector App

The PosiTector App connects a PosiTector SmartLink to your iOS device enabling you to use PosiTector 6000, DPM, SPG or RTR-H probes on your device without the need for a conventional gage body.

Screen fonts, brightness and displayed language are inherited from your smart device settings. Currently, the PosiTector App has language support for English, Spanish, French, German, Chinese and Korean. Screen orientation is fixed to portrait only, rotation to landscape is not supported.

Stored datasets, images and notes are all stored in the PosiTector App (on your smart device). The number of stored datasets is only limited by the memory available on your smart device. If the application is removed or a menu Reset is performed, all stored datasets and associated data is permanently erased.


Prior to uninstalling the PosiTector App or performing a Reset it is recommended that you synchronize/copy measurement data to PosiSoft.net or share the batch data (AirPrint or email report). This ensures that the data is saved for future reference.

PosiTector DPM Probes

PosiTector DPM probes continually measure, calculate and record climatic readings. Two probe models (Built-In and Separate) are offered, as pictured below.

Optionally, the magnetic surface temperature probe can be disconnected from the K-Type thermocouple connector (separate probe models only) and replaced with one of the following K-Type probes:

Hand-held Surface Temperature Probe - for spot checking hard-to-reach surfaces

Self-adhering Surface Temperature Probe - sticks to solid materials including aluminum, wood, concrete, etc. Ideal for unattended monitoring.

Liquid Temperature Probe - general purpose probe with stainless steel shaft

CAUTION: To ensure optimal performance of your PosiTector DPM, do not obstruct the airflow near the air temperature and humidity sensors. Keep fingers away from the sensor, as body heat can cause incorrect readings. Allow time for the instrument to acclimate (see, Operation Overview > Measure Note) and for the readings to stabilize when moving the instrument between different environments. When using the surface temperature probe, do not use excessive downward force, and do not drag it sideways.

More probe information is available at www.defelsko.com/dpm

Protective Cap
PosiTector DPM probes ship with a protective rubber cap (on surface temperature sensor). Remove this cap prior to use. Replace it when the instrument is not in use to protect the probe.

Factory Calibration
Every PosiTector DPM probe is factory calibrated and includes a Certificate of Calibration. This factory calibration information is permanently stored within the probe and cannot be adjusted or overwritten by the user.

Certification
PosiTector DPM probes include a Certificate of Calibration showing traceability to a National Metrology Institution. For organizations with re-certification requirements, instruments may be returned at regular intervals for calibration. DeFelsko recommends that customers establish calibration intervals based upon their own experience and work environment. Based on our product knowledge, data and customer feedback; a one year calibration interval from either the date of calibration, date of purchase, or date of receipt is a typical starting point.

PosiSoft.net

PosiSoft.net is a free web-based application offering secure centralized management of measurement data. It is accessed using a standard internet browser from any location in the world.

  • View and manipulate synchronized measurement data
  • Generate reports with graphs, annotations, and images
  • Share measurement data with authorized users via a secure login from any computer or web-enabled device
  • Export data to popular formats such as XML and CSV (comma-separated values)
  • Securely store (backup) all measurement data in the Cloud


An account is not required to synchronize measurement data to PosiSoft.net.

Synchronize (Sync) with PosiSoft.net

Synchronizing (Sync) is a two-way communication process between the PosiTector App and PosiSoft.net (no registration required). WiFi/cellular internet data connection required.

Stored batch data including datasets, photos, notes and annotations are included in the synchronization. After synchronization, data on the PosiTector App and PosiSoft.net will match (be the same).

New changes made to either will be included and merged during the next synchronization process.

Tip: Prior to synchronizing, it is good practice to change batch names to something more meaningful. This helps identify the batch in the future. Example: Rename "B4" to "Job142-14" or "Section83".

Synchronization can be triggered either manually (Sync Now) or automatically when batch data changes (Auto Sync).

 

Sync Now (Memory Menu)
Immediately initiates synchronization. All batches, datasets, photos, notes and batch names for all probes will be synchronized.

 

Auto Sync (Setup Menu)
When toggled on; datasets, images and notes will automatically synchronize with PosiSoft.net. Synchronization occurs every time batch data changes (new dataset, note, photo, etc.).

The example below demonstrates the PosiTector App with Memory and Auto Sync on. A dataset has been stored within the app and is in the process of synchronizing with PosiSoft.net.

(1) Auto Sync icon (appears when mode is on)

(2) Batch Synchronization status with PosiSoft.net

Yellow icon = batch data has changed since last sync
Green icon = batch synchronized

(3) Synchronization transfer status with PosiSoft.net

Green icon = successfully synchronizing
Red icon = attempting synchronization

If successful communication is not established after a period of time, the app will stop trying and the red icon will disappear. Ensure that your smart device has an internet/cellular data connection.

Auto Sync is an ideal backup solution for your measurement data. Data can be copied back to the PosiTector App on the same smart device or another (ideal for switching between smart devices).

To view/interact with synchronized data on PosiSoft.net, registration of your PosiTector SmartLink is required (free account).

To transfer all stored batches, select Sync Now.

Copy To/From PosiSoft.net (Memory Menu)

Sync Now  synchronizes all batch data for all probes associated with the connected PosiTector SmartLink. Sometimes only a single batch or select batches is desired for transfer. Copy to or Copy from PosiSoft.net allows the selection of single or multiple batches for transfer. Ideal solution for switching between smart devices (phone and tablet). Pickup exactly where you left off.

 

Copy to PosiSoft.net
Select an individual batch or batches to copy to PosiSoft.net. Ideal when you don't require transferring or synchronizing all stored batches.

The selected batches will be copied to PosiSoft.net and you will be returned back to the main measurement screen.

If the batches already exist on PosiSoft.net you will be prompted with an overwrite warning message.

Troubleshooting

When the surface temperature probe is not on a surface, Air Temperature and Surface Temperature appear to be different
Under normal conditions with the surface probe in air Ta and Ts should be within the combined tolerance of each sensor (typically 1°C each). It is possible for the difference to be larger if the surface probe has recently been in contact with surfaces that are at a different temperature than air.

RH value is slow to stabilize
If the probe is exposed to very low humidity for an extended time period and then placed in a high humidity environment, the displayed Relative Humidity (RH) may appear to respond slowly. Allow the probe to stabilize 30 minutes for a change of RH greater than 50%. It may take longer if the probe was left at low RH for several months. To increase response time soak the sensor in a damp face cloth overnight to recondition the RH sensor.

Surface Temperature reads much higher than expected
The probe tip may be dirty or damaged. Clean the probe tip by soaking in water or solvent. If Ts continues to read high then return the probe for service.

Surface temperature value does not agree with expected surface temperature or surface temperature probe is slow to respond
In some cases the surface being measured is very rough and a good thermal connection from the probe tip to the surface is not possible. If possible place a small drop of water on the surface and then place the probe tip into the water drop. Quick and accurate results can be obtained in this manner.
