The PMU-V measuring heads of the humidity and temperature sensors of the series PM-V 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.
The transmitters of the PM-V series are available as rod shaped sensors, but also in two versions for duct mounting.
