The humidity sensors detect the values that are essential for the application: first and foremost the absolute or relative humidity, the ratio, so the humidity of the air, and the enthalpy, heat content. But also the dew point and the dew point temperature and condensation can be measured and controlled. A humidity transmitter, as for example, the HYGRASGARD RFTF works with a well-thought-out principle: it measures the relative humidity and temperature of the air and converts the appropriate parameters to a standard signal 0-10 V or 4… 20 mA. The operator purports a set point by adjusting the humidity control. The humidity controller compares the value now with the coming of the humidity transmitter signal.
The value is too high, the humidity controller automatically activated a fan. The current humidity in the room is too low, the humidity controller starts a humidifier to increase them again. All transmitters of the HYGRASGARD series is the safe and accurate scanning in the foreground. With measuring ranges from 0% to 100% relative humidity at temperatures from-35 C to + 80 C covers S + S moisture sensor a wide range of standard technical applications each, if necessary with tolerances and rule tolerances of up to 2% or 3% R.h.. Tino Schulze, Managing Director of S + S REGELTECHNIK GmbH, explains what other benefits await users when using the HYGRASGARD series: We designed multi-functional all transmitters, to reduce the range of types and to expand the possibilities. So, can be also special customer-specific measuring requirements thanks to the used microprocessors. Our customers can choose between active and switching outputs, devices with or without display, upon request also with plug-in probe also.” In addition to the room humidity temperature sensor RFTF HYGRASGARD series of pendulum humidity temperature sensor HYGRASGARD are in the S + S RPFTF, as well as more surface moisture sensors and channel moisture sensors available.
