Air Temp. / rel. Humidity

⇓  Description

The sensor is used for simultaneous recording of air temperature and relative humidity.As for the temperature sensor element is a highly sensitive PTC resistor whose resistance changesproportional to the temperature.

The relative humidity is measured by a capacitive sensor whose capacitance is proportional torelative humidity changes.
The recorded data will be in a signal processor pre-processed and in the F-bus protocol to the display device or a further Signal processing units supplied. The distance between the sensor and this unit can be on a Twisted pair up to 700m and go up to 3000m with additional repeater modules.

The sensors are optional build in a temperature-resistant weather housing made from plastic.
