Temperature Instrument

Temperature: 0 ... +200°C, Humidity: 0 ... 100% rH, pmax: 25 bar, tmax: +200°C
Output: 2x 4 - 20 mA, Temperature: ±0,1°C
Humidity: ±2 % rH.The range AFK-G humiditytemperature sensors are sensors for measuring relative humidity and temperature (optional) in air and other non-aggressive gases for an operating temperature to 200 °C. The high pressure variant can be used up to a pressure of 25 bar. The sensors are thus ideally suited for measuring humidity in industrial processes. The sensors are based on capacitive metrology which is reasonably-priced, maintenance-free and highly accurate.
The change in capacitance is converted to an electrical output signal by electronics normally mounted on the humidity sensor element. Both parts form a capacitive humidity sensor that can be adjusted using humidity references. Accuracy is approximately ± 2% rH. The transmitters offer a 4 - 20 mA analogue output for relative humidity and a second 4 - 20 mA output for temperature when specified.
