Humidity & Temperature Sensors

Humidity & temperature measurement is used in potentially explosive areas. The intrinsically safe humidity and temperature sensors with ATEX licence made by Galltec+Mela are certified for use in potentially explosive areas in the categories 1/2 G and 2 D.

The sensors with an analogue output signal 4...20 mA have been designed electrically so that power supply units of up to 24 V can be used. Standard measurement ranges of the sensors are 0...100 %rh and 20...+80 °C. Special versions are available on request.

The inherently safe instruments made by Galltec+Mela can be used for a wide range of applications thanks to their certification and in addition to that, offer a real alternative to other often very costly transmitters.

Plug-and-Measure / Series PM15P:

The PMU-P measuring heads of the humidity and temperature sensor PM15P are calibrated and thus enable a replacement within seconds. Replaced measuring heads can be recalibrated in the factory.

The transmitter with the hx processor uses the values of the relative humidity and the temperature to calculate the dew point temperature, the enthalpy, the mixing ra­tio, the absolute humidity or the wet-bulb temperature, in accordance with the laws of physics. The values are emitted at two analogue outputs with the standardised signals 0...10VDC, 0...1VDC, 0...20mA or 4...20mA.
