AH-40W TYR-1 LCD

HYGRASREG® AH-40W TYR-1

Item No. 1202-1065-0221-000
EAN 4 251325 615523

Electronic hygrostat and humidity sensor HYGRASREG® AH - 40 with one switching output, adjustable switching threshold and display for indicating actual humidity (accuracy class ± 2.0 % r.H.) and for setting the target humidity.

They are used to control and monitor the relative humidity, e.g. in laboratories, production facilities, climatic test cabinets, indoor swimming pools, greenhouses, etc. to control humidifying and dehumidifying equipment. These measuring transducers are designed for exact detection of humidity. The AH - 40 uses a digital, long-term stable sensor as a measuring element for measuring humidity. It is used in dust-free, unpolluted, non-aggressive air.

Displaying The 1st line of the display shows the relative humidity.
The 2nd line shows on the left side the information
regarding the switching status of the relay (as a circuit),
as well as the switching value readout in % r.H.
on the right side (adjustable using the set potentiometer).
Circuit, empty = relay in idle state
Circuit, full = relay energised
Function

The relay output is triggered (contact 13 -11 closed) if the humidity
switchpoint is not reached and opens (contact 12 -11 closed)
in the event of a fault (power failure, condensation)

LED short pulses =
relay active → switchpoint not reached

LED long pulses =
relay inactive → switchpoint exceeded
