Relative humidity transmitter for explosive areas VAISALA
HUMICAP® HMT360

Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMT360
The HMT360 transmitter can be installed directly into an explosive area, even those classified as having a constant risk of explosion (Zone 0 / Division 1). The HMT360 complies with strict classifications from FM (USA), PTB (CENELEC, Europe), CSA (Canada), TestSafe (Australia) and TIIS (Japan).

Five models are available for a variety of applications:
- HMT361 for wall mounting
- HMT363 for confined spaces
- HMT364 for high pressures (up to 100 bar/1450 psig) or vacuum
- HMT365 for high temperatures (up to +180 ºC / 356 °F)
- HMT368 for pressurized pipelines as high as 40 bar (580 psig)

The transmitters measure relative humidity between 0...100 %RH. As calculated variables they also output dewpoint and wet bulb temperature, mixing ratio and absolute humidity. The structure of the transmitter is modular: the interchangeable probes are easy to remove and calibrate.
