Temperature transmitter for hazardous areas

22 February 2021

Vaisala has launched a new humidity and temperature transmitter series – HMT370EX – for applications in hazardous and explosive environments.

The entire transmitter can be installed directly in explosive areas, up to zone 0 and zone 20.

A rugged display allows the unit to withstand continuous exposure to potentially explosive areas that contain flammable gases or dust. Typical applications might include paint booths in the automotive industry, hydrogen cooled generators in electricity generation, chemical plants and processes, baking industry, pharmaceuticals manufacturing, oil and gas drilling platforms, and fuel tanks and storage.

The range consists of the transmitter and a selection of probes. The transmitter is equipped with an intuitive graphical display for  ease of use. Hand-detachable measurement probes and easy product configuration and calibration with Vaisala Insight PC software is said to enable smooth maintenance, minimising any measurement downtimes.

In addition to measuring relative humidity and temperature, the transmitter also outputs dew point temperature, wet-bulb temperature, absolute humidity, mixing ratio, water concentration, water mass fraction, water vapour pressure, and enthalpy.
