Temperature and humidity sensor for ventilation duct - 4..20mA
Reference GPTSV120R
Product features Temperature and humidity sensor for ventilation duct - 4..20mA
The digital design with microprocessor ensures long-term stability of the parameters, temperature compensation of the humidity sensor and signaling of fault conditions. The state-of-the-art polymer humidity sensor ensures long-term data stability and resistance to water condensate.
The output signals of the measured quantities are two galvanically isolated 4 to 20 mA current signals, set by the manufacturer as follows:
- output quantity 1 : relative humidity, range from 4 to 20 mA corresponds to 0 to 100% RH
- exit 2 : temperature, range from 4 to 20 mA corresponds to -30 ° C to 125 ° C
