The temperature capillary pipe controller TR 12 operates on the principle of fluid expansion. A change in the temperature in the sensor effects a change in volume. This force, in turn, operates a floating changeover contact via a diaphragm. . The equipment is supplied on request with an actual temperature display. The sensors are located in an immersion pipe. The cables are connected via connecting terminals 1,5 mm². Also on request, the equipment can be supplied with gold contacts.
