Humidity probe - FLC-200

The newly developed FLC200 humidity transducer for relative humidity consists of a new long-term stable, waterproof and capacitive humidity sensor element. The evaluation electronics are manufactured in hybrid technology and guarantee a long-term stable output signal of 0-5V DC. The probe is calibrated using a computer-controlled climatic chamber. Measurement and calibration data for each probe can be requested as required. The measuring cell is separate from the electronics and its connection. The evaluation electronics and cable entry have protection class IP65. The protective cap of the sensor is equipped with a GORETEX™ dust filter. The sensor and electronics are protected by a robust wall housing. The special features are high basic capacity, high sensitivity, convincing long-term stability, high resistance to pollutants, mechanically robust, low temperature sensitivity and can be used in the entire humidity range. An internal heater ensures that condensation is prevented even at a relative humidity of 100%, so that the probe can continue to provide accurate readings. Its field of application is in ventilation and air-conditioning technology, meteorology and fruit warehouses.
