2-Wire Temperature Transmitter for RTDs
Conax Model: HPT 
The Conax Model HPT is a low cost, 2-wire, non-isolated temperature transmitter for RTD sensors, and is designed to fit in our popular T11 model terminal head.
The HPT housing has a removable base allowing access to the electronics for the purpose of temperature range changes, which are easily accomplished with plug-in resistors.
