COMET T3110EX Intrinsically safe humidity and temperature transmitter with 4-20mA output

The Comet T3110Ex is a high-precision temperature and relative humidity transmitter specifically designed for use in potentially explosive atmospheres (ATEX). An intrinsically safe industrial sensor designed for monitoring temperature and humidity in hazardous zones. It features dual 4-20 mA outputs, a two-line LCD, and is certified for ATEX Zone 1 and 2 environments.

COMET T3110EX Intrinsically safe humidity and temperature transmitter with 4-20mA output

The T3110Ex is a robust device that converts signals from its internal sensors into standard analog current outputs. Its microprocessor-controlled design ensures long-term stability and enables temperature compensation for the humidity sensor. Beyond basic temperature and humidity, the device can calculate derived values such as dew point, absolute humidity, and enthalpy. Measuring ranges can be easily configured via PC using free software from Comet.
