2-Wire Temperature Transmitter for RTDs or Thermocouples
Conax Model: HPTI
The Conax Model HPTI is a small, isolated, 2-wire temperature transmitter for RTD or thermocouple sensors, and is designed to fit in our popular T11 model terminal head.
The HPTI 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.
