Relative humidity transmitter RAF(H)/A

duct-mounthigh-precision

The high-precision RAF(H)/A humidity sensor with transducer (< 2% r.H.) measures the relative humidity 0...100% r.H. of the ambient air by a capacitive sensor and transforms it to a standardised output signal 0-10 V or 4-20 mA. The humidity sensor is protected against contamination by a screwable stainless steel sinter filter. The accuracy is confirmed by a calibration certificate with traceability to a national standard.
