Continually monitoring temperature is one of the most important tasks for ensuring the functionality, reliability, and operational readiness of a transformer. Two generic thermometer technologies – the Bourdon and the expansion bellows principle – have developed over the decades and are widely used today. MESSKO customers can obtain both these proven technologies from one source. The MESSKO BeTech thermometer range relies on proven bellow-type technology, while the MESSKO COMPACT and TRASY2 series are based on the well established Bourdon principle.

MESSKO BeTech
The MESSKO BeTech oil and winding thermometer with bellow-type technology comprises four main components: the temperature sensor, the capillary tube, the first expansion bellows for displaying the measurement and actuating the micro-switch, and the second expansion bellows for compensating for the ambient temperature. As with the Bourdon technology, the measuring system is filled with a liquid but is depressurized. With bellow-type technology, the intelligent interaction of the functional units ensures that the micro-switches are switched correctly.
