TEMPERATURE RTD100 MODULE INSTRUCTIONS
Your nVision has the ability to measure temperature very accurately if populated with an RTD100 module. With this system you may connect your resistance
temperature detector (platinum RTD) or platinum resistance thermometer (PRT) to the nVision using the provided IP67 rated connector system (P/N: 3953).
Once the sensing element is connected, you may display the temperature reading in your desired unit. The nVision can also measure electrical resistance (Ω)
to help in troubleshooting your resistance based sensing element.
Temperature Coecient of Resistance (TCR)
Your nVision comes pre-loaded with several common RTD sensing element TCR values with the appropriate Callendar-Van Dusen Coecients to convert your
resistance measurement to the appropriate temperature measurement. The available 100Ω platinum RTD TCRs are:
•
Pt100 (385) Euro
•
Pt100 (3911) US
•
Pt100 (3926)
Simply select the desired TCR or coecient values in CrystalControl for use on the nVision. You may also view the Summary page to conrm
you have selected the correct setting for your sensing element.
