DEW POINT MONITOR -TPW / TPWEXT
TPW/TPWEXT
Anwendung
The Dew Point Monitor measures the relative humidity on pipes, cooling ceilings or other surfaces and transfers the value as a linear analogue 4…20 mA output signal. The device also features a changeover contact for which the limiting value can be adjusted between 75 and 100 % r.h. with the help of a potentiometer. This way the respective signal can be transferred to the control/DDC when condensation is forming in order to activate the respective actuators.
