Overview
|
- Six interchangeable probe models for a variety of applications:
- HMT361 for wall mounting
- HMT363 for duct mounting and tight spaces
- HMT364 for high pressures up to 100 bar and vacuum conditions
- HMT365 for high temperatures
- HMT367 for high humidities
- HMT368 for pressurized pipelines up to 40 bar
- Intrinsically safe - the whole transmitter can be installed into the explosive area
- Complies with classifications from VTT (CENELEC, Europe), FM (USA), CSA (Canada), TIIS (Japan), and PCEC (China), VTT (IECEx)
- The interchangeable probe module contains all calibration coefficients, so a calibrated probe can be switched in the field without the need to input any data manually
