Built-in Alarm The HDT provides a factory programmable dew point alarm signal through a digital output pin. Additionally, relays or external devices can be operated through the analog or digital loops. Connections The HDT interfaces with both metric 14 mm x 1.25 mm threads and unified 3/4"-16 threads. It is also available in other thread forms, refer to specifications. The HDT connects through an inexpensive twoconductor cable over long distances. Measurement Accuracy/Stability The HDT transmitter uses a multi-point calibration table which provides temperature compensated dew point readings...
