The dew point controller TW/A measures the relative humidity 0...100% r.H. via the contact surface of the contact block, e.g. on cooled pipes, surfaces or cooling ceilings. For further processing, it provides a linear output signal 0-10 V, 4-20 mA or a change-over contact. The dew point controller with change-over contact has a 2-digit LED display which visualize the actual value of % r.H., the limit setting 5...95% r.H. and the exceeding of the limit. The sensor element is mounted inside the contacting block and is protected by a sinter plate. Due to its geometric shape the dew point controller allows an easy mounting on pipes by a tension band.
