RELATIVE HUMIDITY TRANSMITTER

HD9513T… Three wire relative humidity transmitter. Measuring range 5...98%R.H. The R.H.
sensor can work in the temperature range between -30°C and +130°C. Power supply 10,5...35Vdc or 12...24Vac: voltage output 0...1Vdc. Power supply 18...35Vdc or 24Vac: voltage output 0...10Vdc.

Relative humidity and temperature transmitters convert the variation that occurs simultaneously inside a relative humidity capacitive sensor and a resistive Platinum sensor both into a 4÷20mA linearized signal and, depending on the various models, into 0÷1V, 0÷10V, 0÷20mA or 4÷20mA signals.
They are distinguished in two-wired current-looped passive transmitters, separately power-supplied active transmitters (with voltage usually of 24Vac), and finally passive and active transmitters which can work with either of the two possible kinds of power supply - two wires with current loop, or grid of 24Vac.
