Capillary thermostat

Maximum flexibility meets precision: Accutherm Capillary Thermostats.

Accutherm Capillary Thermostats have a very simple structure but require precision work to calibrate the membrane.

The thermostat temperature sensor consists of four components: The thermostat temperature sensor consists of four components: sensor, capillary tube, membrane, and filling medium. When the sensor is heated, the filling medium heats up, expands and increases the pressure in the closed-circuit system. This increase in pressure actuates a snap-action switch which opens the contacts in the electrical circuit.

Accutherm Capillary Thermostats and Safety Temperature Limiters are available in single-pole and multi-pole versions. We design and create individual solutions according to customer-specific requirements.
