ATEX certified sensors for use in “Ex” zones

ATEX certified sensors for use in potentially explosive areas “EX” are part of the programme offered by our partner COMET. The sensors provide accurate measurements of relative humidity, temperature and other units of humidity.

COMET System from the Czech Republic has been creating innovative control solutions by manufacturing dataloggers since 1991. These are used to document environmental conditions in production plants, warehouses and the cold chain. COMET instruments are characterised by high-quality measurement components, precision measurement and monitoring. The monitoring process consists of measuring, recording and managing data. Depending on the stability of the data, criteria for triggering alarms are set.

ATEX certified sensors for use in Ex zones – features:

  • measuring transducers
    • for relative humidity and temperature
    • for dew points (Dew point)
    • for atmospheric pressure
    • for digital inputs
    • for CO2
  • different types of output
    • 4-20 mA
    • 0-10 V
    • RS323/485
    • Ethernet (PoE, depending on model)
    • IoT (Sigfox)
  • industrial design
    • with integrated sensor
    • with external probe and duct connection (protection class IP65)
  • ATEX design allows use in potentially explosive areas (Zone 2), on certain models
  • relay output 250 Vac/8 A or 50 V, on certain models

The ATEX certified transducer range includes the following transducers: T3110Ex, T3111Ex, T3113Ex. All selected models are available from us!


High-precision humidity sensors, modularity and multi-connectivity. The sensors come with a warranty. The measured values can be converted into other units of humidity using the function, such as: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy.

At the ELPRO Calibration Laboratory, which is accredited to SIST EN ISO/IEC 17025:2017, we can also calibrate your sensors.

For use in:

construction, infrastructure, heavy industry, meteorology, pharmaceuticals, laboratories, warehouses and wherever optimum humidity and temperature conditions need to be ensured.

ATEX-certified transducers are suitable for indoor and outdoor use, in potentially explosive areas.
