for plaster ceilings and piping
description
Clina Dew Point Sensors register any possible accumulation of condensation at the capillary tube mat or in its immediate surroundings, thereby changing their electric resistance. This resistance change in the sensor is recognised by the room temperature controller TR1 and TR2/3 and causes the control valve to close. It therefore protects the cooling surfaces effectively against damage.
