The humidity transmitter FS3130 detects the temperature and relative humidity in air ventilation ducts and converts the measured values into an active 0-10 V or 4-20 mA output signal. In addition, a further thermodynamic indicator calculated from the measured values can be transmitted at the third output, e.g. mixing ratio, absolute humidity, dew point temperature or wet bulb temperature are output. The third output signal can be selected via DIP switch. The moisture meter has a continuous heating function and is specially designed for use in the high humidity range of 95 ... 99% relative humidity. Thereby, a much faster reaction rate with changes in relative humidity, even in the range > 95% r.h. is reached. The combined digital humidity and temperature sensor is heated approx. 3K above ambient temperature. From the measured rel. humidity at this overtemperature, chip temperature of the sensor and the ambient temperature (temperature measuring element in the second probe) is calculated and output the "true" relative humidity. The sensor technology is optimally protected against contamination by a screwable sintered filter. As an option, a potential-free changeover contact and / or a backlit LCD display are available. The contents of the backlit display can be rotated by the menu in 90° increments. The actual value, the set switching threshold, the relay status, the MIN / MAX measured values of the selected interval, etc. can be read off. In addition, the switching threshold, hysteresis, offset value, etc. can be set directly on the device.
