Issue
Do Xenta controllers support PT100/PT1000 sensors for measuring the temperature?
Environment
Xenta Controller
TAC Menta
PT100/PT1000 Temperature sensors
Cause
Requirement to measure the temperature using PT100/PT1000 Temperature sensors.
Resolution
PT100/PT1000 sensors are not supported within any of the Xenta controllers. The following is a method to achieve this using Menta:
When using PT100/PT1000 to connect to a thermistor input, Menta Logic is required to add a polynom using the expression block.
It is also strongly recommended to implement some calibration software in Menta to allow for fluctuations in resistance for every input that PT100/PT1000 is connected to. If a sensor is replaced / changed, re-calibration will be required.
Sample experiment results and Menta Logic's are available here.
