Description
High-temperature humidity Sensor – ARFTP/R-xxx-I/HT
For measuring relative humidity and temperature outdoors or in areas with increased protection requirements. The transmitter records temperature and relative 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. Depending on the version, different measuring ranges are available. The Sensor is long-term stable and does not need to be recalibrated. Overview of humidity sensors
