Product details about "External temperature and humidity probe - 4..20mA"
The temperature and humidity measurement sensors are located in an external probe connected to the wired electronic head. The probe is placed in the measured area and cannot be disconnected from the electronic head. The sensor head is designed for wall mounting.
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
- output value 2 : temperature, range from 4 to 20 mA corresponds to -30 ° C to 105 ° C
