Overview

The intrinsically safe HMT370EX is an ideal solution for hazardous areas up to Zone 0 and Zone 20. In addition to measuring relative humidity and temperature, the transmitter also outputs other humidity parameters: dew point temperature, wet bulb temperature, absolute humidity, mixing ratio, water concentration, water mass fraction, vapor pressure, and enthalpy value. There are also special models available for measuring trace moisture in oil and jet fuel oil. Typical application scenarios for $r $n include fuel storage tanks, chemical production, pharmaceutical and food processing, biogas production, paint workshops, and any other applications that require intrinsic safety in terms of humidity or trace amounts of water in oil

Intrinsically Safe Temperature and Humidity Transmitter Series HMT370EX

Suitable for Zone 0 and Zone 20

The intrinsically safe HMT370EX is an ideal solution for hazardous areas up to Zone 0 and Zone 20. In addition to measuring relative humidity and temperature, the transmitter also outputs other humidity parameters: dew point temperature, wet bulb temperature, absolute humidity, mixing ratio, water concentration, water mass fraction, vapor pressure, and enthalpy value.
There are also special models available for measuring trace moisture in oil and jet fuel oil.
Typical application scenarios include fuel storage tanks, chemical production, pharmaceutical and food processing, biogas production, paint spraying workshops, and any other industry or process that requires intrinsic safety for measuring humidity or trace moisture in oil.

main advantages

intrinsic safety

The entire HMT370EX transmitter can be directly installed in explosive areas.
It can withstand continuous exposure to potentially explosive environments containing flammable liquids, gases, or dust.
Running in any of these environments does not require additional protective covers.

Detachable probe

It is easy to replace and disassemble the probe for calibration outside of hazardous areas without disassembling the entire transmitter.
Since the settings before disassembly can be restored from the transmitter, connecting a new probe only requires a simple reconfiguration.

Easy to configure

Output configuration and measurement calibration adjustments can be directly performed on the optional local display interface.
Alternatively, the transmitter can be connected to the Vaisala Insight computer software and configured together or separately for the transmitter and probe.
