West Castle Alpine Monitoring System

HMP45 Temperature & Relative Humidity

The HMP45C Temperature and Relative Humidity probe contains a Platinum Resistance Temperature detector (PRT) and a Vaisala HUMICAP 180 capacitive relative humidity sensor.
The HMP45C can be powered continuously or the power may be switched to conserve battery life. The HMP45C consumes less than 4 mA current at 12V. Do not attempt to extend this cable beyond the length provided by CS. This will induce noise on the line, producing errors in the data. CS provides cicuitry at the end of each cable. Ensure the heat shrink is protecting it from the external environment. Solder joints within the curcuitry have been known to weaken and break. Calibration is conducted at CS. CS offers a recalibration service for a nominal fee.
