Self-controlled heater in polymer technology integrated in a potentiometer

Electronic components such as sensors and actuators are frequently subject to changes in temperatures. Especially fork lifts trucks being used in cooled warehouses or sensors in building technologies during winter time transfers thermo cycle stress to electronic equipment. Electronic components need to survive these conditions.

Frequent and rapid changes in temperatures mostly are the reason for mechanical stress. Consequently leakage current, short-circuit or total failure occur. In order to avoid condensation and freezing of the sensor. It can be protected by a hermetic barrier. Usually absolutely sealed systems may not be achieved by this method, because one of the characteristic of plastic is the permeation.
