Ceres Model A70-H Relative Humidity
Accuracy: +/-2% R.H.
Ceres provides an analog output signal proportional to relative humidity. The A70-LPDD loop indicator can be used to display the senses relative humidity with the 4-20 mA output. These units are used in conjunction with electronic data collection systems or for input to control systems. They are readily combined with meter relays to provide custom controls.
Systems are available with outputs of 0-1 V or 4-20 mA. Ceres is powered from 6 - 30 VDC.
Relative humidity is sensed by a thin-film polymer capacitor sensor with excellent durability in harsh environments. The relative humidity sensor is protected by a hydrophilic membrane under a wire mesh screen.
Each system is provided with a detailed instruction manual.
