HYGRASREG RH - 30
Electronic room hygrostats and humidity sensors HYGRASREG
two switching outputs, adjustable switching thresholds, with or without an optional display for
displaying ACTUAL humidity (accuracy class ± 3 % r.H.) and for setting the target humidity.
They are used to control and monitor the relative humidity, e.g. in ventilation and air conditioning
ducts, laboratories, production facilities, climatic test cabinets, indoor swimming pools, green-
houses, etc. to control humidifying and dehumidifying equipment. These measuring transducers are
designed for exact humidity measurement. RH-30 uses a digital long-term stable sensor as a
measuring element for humidity measurement. Applications in dust-free, pollutant-free, non-
aggressive air.

1st step: wire contacts 11 - 12.
When actual humidity falls more than 3 % r. H. (hysteresis) below switching threshold S1,
changeover contact switches to 11 - 12.
2nd step: wire contacts 21 - 22.
When actual humidity falls more than 3 % r. H. (hysteresis) below switching threshold S 2,
changeover contact switches to 21 - 22.
Terminal 2: Output Humidity ^ = 0 - 100 % r. H.
1st step: wire contacts 11 - 13.
When actual humidity exceeds switching threshold S 1, changeover contact switches to 11 - 13.
2nd step: wire contacts 21 - 23.
When actual humidity exceeds switching threshold S 2, changeover contact switches to 21 - 23.
Terminal 2: Output Humidity ^ = 0 - 100 % r. H.
