HYGRASREG® KH-40Electronic HYGRASREG® KH - 40 hygrostat and humidity measuring transducer 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. The sensor device serves to control and monitor the relative humidity e.g. in humidifying and dehumidifying equipment, ventilation and air conditioning ducts, laboratories, production facilities, climate test chambers, indoor swimming pools, greenhouses, etc. It provides precise detection of humidity. The KH-40 has a digital, long-term stable sensor as a measuring element for humidity. It is used in dust-free, unpolluted, non-aggressive air.

H. ); at + 25 °C, otherwise ± 3 % Output potential-free changeover contact (24 V), 1 A ohmic load Sensor protection plastic sinter filter, Ø 16 mm, L = 35 mm, exchangeable (optional metal sinter filter, Ø 16 mm, L = 32 mm) Setting range 5...95 % r. H. Ambient temperature storage –35...+85 °C; operation – 30...+75 °C, non-precipitating Process connection by mounting flange, plastic (included in the scope of delivery) Protective tube PLEUROFORM, material polyamide (PA6), with torsion protection, Ø 20 mm, NL = 235 mm (optionally 100 mm), vmax = 30 m/s (air) (option on request in stainless steel V2A (1.4301), Ø 16mm) Electrical connection 0.14 - 1.5 mm² via terminal screws Cable connection cable gland, plastic (M 16 x 1.5; with strain relief, exchangeable, max. inner diameter 10.4 mm) or M12 connector according to DIN EN 61076-2-101 (optional on request) Housing plastic, UV-stabilised, material polyamide, 30 % glass-globe reinforced, with quick-locking screws (slotted/ Phillips head - combination), colour traffic white (similar to RAL 9016), housing cover for display is transparent ! Housing dimensions 72 x 64 x 43.3 mm (Tyr 1 with Display) Cable gland M 16 x 1.5, including strain relief, exchangeable, max. inner diameter 10.4 mm Long-term stability ± 1 % per year Protection class III (according to EN 60 730) Protection type IP 65 (according to EN 60 529) housing only! Standards CE conformity, electromagnetic compatibility according to EN 61326, according to EMC Directive 2014/ 30/ EU Display two-line display with illumination, cutout approx. 36 x15 mm (W x H), for displaying actual humidit and for setting the target humidity 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 |
