     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
