Vaisala HMT370EX Intrinsically Safe Humidity and Temperature Transmitter

The Vaisala HMT370EX is an intrinsically safe humidity and temperature transmitter for hazardous areas up to Zone 0 and Zone 20. Certified to ATEX, IECEx, FM, CSA and UKEX, it installs directly in explosive gas and dust atmospheres across oil and gas, mining, chemical processing, paint booths and fuel storage. Its Vaisala HUMICAP® sensor measures relative humidity and temperature, calculates dew point, wet-bulb temperature, absolute humidity and more, and connects to your control system through a 2-wire, loop-powered 4–20 mA output.

Choose the probe to suit the process: the HMP371 for wall mounting, HMP373 for confined spaces, HMP374 for pressurised spaces, HMP375 for high temperatures, HMP377 for high humidity and HMP378 for pressurised pipelines. Temperature coverage runs from −70 to +180 °C depending on the probe. Full details are in the Vaisala HMT370EX datasheet.
