I installed two temperature sensors, one on the BRS vacuum can and one on the ground T240 at EX. They are temporarily being read on the PEM_Tiltmeter_T and PEM_Tiltmeter_Y channels respectively.

H1:PEM-EX_TILT_VEA_FLOOR_T_MON   =   BRS temperature sensor

H1:PEM-EX_TILT_VEA_FLOOR_Y_MON   =   GND_T240 temperature sensor

The temperature sensors consist of a 10k-ohm thermistor bridge powered by a 9V battery each. There is no amplification, so the calibration should be ~ 1/2 * beta / (10k) * 9V = 0.2 Volts / Kelvin , where beta value for the 10k thermistor is roughly 450 ohms/Kelvin.
