The HX-9100 Dew Sensor is used to prevent condensation on surfaces such as cold water pipes and windows. It senses the dew point precisely via a conductive polymer sensing element and signals condensation conditions to a controller. Two variants exist: an open collector ON/OFF output (-8001) for digital inputs, and an active 0…10 V output (-9001) for DDC controllers.

Застосування
- Preventing condensation on cold water pipes and windows
- Cool ceiling systems (chilled ceilings, with suitable delay function in the DDC controller)
- Use with Johnson Controls System 91 controllers to provide override functions when condensation is forming
- Usable with any DDC regulator managing digital signals; can be used in conjunction with TC-9100
Особливості
- Determines precisely the dew point with electronic measurement — achieve optimal efficiency for cool ceiling systems
- 0…10 V or open collector output — can be used with any DDC regulator managing digital signals
- Small hysteresis of 1…2% RH avoids oscillations of the information
- Requires a suitable delay time in the DDC controller (DX-9100, FX, etc.) for chilled ceiling applications

to the off position for a suitable time).
It can be used in conjunction with the TC-9100 and, in
general, with other controllers not equipped with the
possibility to define a delay interlock time, only for
cold water pipe applications, where there is usually a
small condensation on the pipe and therefore the HX
output remains active for a suitable time (the time
necessary to the valve to close the flow of cold water
and recover from the high humidity situation).
