FunctionThe humidistat uses a synthetic element as sensor medium. The synthetic element stretches as the humidity increases and shrinks as the humidity decreases. These changes are transmitted to a microswitch.The setpoint knob affects the position of the microswitch in relation to the synthetic element. The setpoint can be set at between 35…95% RH.Synthetic ElementWe have developed a new synthetic element that gives a high accuracy at a low cost.Setpoint knob can be lockedIn order to eliminate the risk of tampering, the setpoint knob can be locked by means of a locking screw under the cover.Typical applicationsCan be used to control a humidifier or a dehumidifier or for on/off controlling of a fan. Can also be used to alarm when the humidity exceeds or falls below a pre-set level.
