Temperature and Humidity Monitoring Board for PANDA

The THMP has been developed to monitor the temperature and humidity inside the electromagnetic calorimeter (EMC) of the PANDA target spectrometer. Therefore it has 64 channels and is designed to read out PT100 temperature sensors and HIH-4000 humidity sensors. This device has been constructed to operate in a temperature range from -30 °C to +30 °C. To cover the whole temperature range of the EMC, the measurement range will also be from -30 °C to +30 °C with a resolution of 0.05 K. The relative humidity (RH) can be measured in the range from 0 to 100% RH with an accuracy of 3.5%. For the read-out of this device a CAN interface is foreseen.

The THMP should fulfill the environmental requirements of operating in the cooled area of the EMC. Different tests were carried out to verify this.
