HYGRASREG AH - 30
Electronic on-wall hygrostat and humidity sensor HYGRASREG
thresholds, optional with or without display indicating the actual humidity, accuracy class ± 3 % r.H. It is used to control and monitor the rela-
tive humidity, e.g. in venti lation and air conditioning ducts, laboratories, production facilities, climatic test cabinets, indoor swimming pools,
greenhouses, etc. to control humidifying and dehumidifying equipment. This measuring transducer is designed for exact humidity measure-
ment.

st
step: wire contacts 4 - 5.
When actual humidity falls more than 3 % r. H. (hysteresis)
below switching threshold S1,
changeover contact switches to 4 - 5.
2 nd step: wire contacts 7 - 8.
When actual humidity falls more than 3 % r. H. (hysteresis)
below switching threshold S 2,
changeover contact switches to 7 - 8.
Terminal 2: 1x 0 - 10 V equivalent to 0...100 % r. H.
st step: wire contacts 5 - 6.
When actual humidity exceeds switching threshold S 1,
changeover contact switches to 5 - 6.
nd
2 step: wire contacts 8 - 9.
When actual humidity exceeds switching threshold S 2,
changeover contact switches to 8 - 9.
Terminal 2: 1x 0 - 10 V ^ = 0 - 100 % r. H.
