HYGRASREG® TW-W EXTERN DISPLAY

Item No. 1202-1015-0221-030
EAN 4 251325 616469

The dew point control switch HYGRASREG® TW is installed on cooling or cold-water piping, or on cooled surfaces. It reliably detects formation of condensation by means of its humidity and temperature sensor (no conductivity measurement) and thanks to its patented measuring method, the pro-dynamic cross convention (Patent No. DE 10 2012 015 726.6), an exact measurement result, with ⁄ without optional display.

Dew point temperature is that temperature at which air reaches the state of saturation and water vapour starts to condensate. Facilitated by the measuring range of 0...100 % relative humidity of the TW-U and by the adjustable threshold value of 75...100 % relative humidity of the TW-W, it is possible for example to operate cooling ceilings so that the switching output of the dew point monitor, the DDC, is activated and then triggers a heater or other control elements thereby preventing the formation of dew before dew builds up on pipes or cooling ceilings of the property to be monitored.

Power consumption	< 1.1 VA ⁄ 24 V DC ; < 2.2 VA ⁄ 24 V AC
Sensors	digital humidity sensor with integrated temperature sensor, low hysteresis, high long-term stability
Output signal	potential-free changeover contact (24 V), 1 A ohmic load
Sensor protection	membrane filter
Measuring range	formation of dew is detected at 75...100 % r.H. on the TW-W, switching (switchpoint adjustable by potentiometer, factory setting 75 % r.H.)
Electrical connection	0.14 - 1.5 mm² via terminal screws
Enclosure	plastic, UV-stabilised, material polyamide, 30 % glass-globe reinforced, with quick-locking screws (slotted ⁄ Phillips head - combination), colour traffic white (similar to RAL 9016), enclosure cover for display is transparent !
Enclosure dimensions	72 x 64 x 43.3 mm (Tyr 1 with Display)
Cable gland	2x M 12 x 1.5 (Y-adapter); with strain relief, exchangeable, max. inner diameter 6 mm
Installation	TW with strap for direct mounting on pipes or for direct mounting on flat surfaces (e.g. walls, ceilings) TW - external with detached sensor head (cable length KL = 1.5 m) for mounting on pipes
Protection class	III (according to EN 60 730)
Protection type	IP 65 (according to EN 60 529)
Standards	CE conformity, electromagnetic compatibility according to EN 61326, according to EMC Directive 2014 ⁄ 30 ⁄ EU
Function	The relay output is triggered (contact 13 -11 closed) if the pre-set switchpoint (factory setting 75 % r.H.) is not reached and opens (contact 12 -11 closed) in the event of an error (power failure, condensation). LED short pulses = relay active → switchpoint not reached ACTUAL humidity < pre-set switchpoint (no condensation) LED long pulses = relay inactive → switchpoint exceeded ACTUAL humidity > pre-set switchpoint (condensation)
