Relative humidity and temperature transmitter
2 - 98 %RH, -20 - 85 °C | H-UTA.32 UPSI France

This miniature module is entended to be associated to a probe of humidity and temperature measurement F-TUCN.33N or P. It provides a stabilized power supply for the probe, performs the signal acquisition of measurement in frequency and delivers a DC linear current proportional to the relative humidity level according to the 4-20 mA two wires standard system and a variable resistor proportional to the temperature (thermistor NTC or platinum PT1000).
This system is characterized by an operating voltage and a measurement current carried by the same two wires without decoding. The measurement current which is mixed with the consumption current, is regourously independent from the voltage supply in a proportion of 600 % and the charge resistance could reach 1500 Ω.
