Description
Outdoor combination Sensor for relative humidity and temperature – ARFT/R-xxx-I/S
For measuring relative humidity and temperature outdoors or in spaces with increased protection requirements. The transmitter records temperature and rel. humidity via an internal Sensor and converts it into a standardized analog output signal 0-10V or 4-20mA. The active outputs are available in every version; a passive temperature Sensor can also be connected. The Sensor is long-term stable and does not need to be recalibrated.
