Hydraulic Thermostat

Hydraulic Thermostat

Expo capillary thermostat have proved effective as regulating and controlling elements in electric ranges, washing machine, storage heaters, heating appliances, deep fryers, water bath, oil bath etc. These thermostats are intended to regulate the temperature of liquids, gases and solids. Manufacturing of these thermostats requires the finest workmanship.

Operation

The principle by which our thermostats operate is that of liquid expansion. The hydraulic thermal system consists of a sensor, the capillary tube and the diaphragm. When the sensor heats up, the liquid expands through the capillary tube into the diaphragm where a working stroke is produced, by which a snap action switch is actuated which opens or closes the circuit.

Physical Characteristics

The standard control knob is black plastic molding with white scale markings. The switching mechanism is mounted on ceramic base with steel body. The capillary is made of copper, which works as a connection between main bodies, the bulb which is made of copper works as a sensor. The capillary and the bulb are also available in stainless steel.

Mounting

The thermostat are operated by a knob put on the spindle & positioned on zero. On principle the bulb should be mounted so that it can sense the temperature and can be removed without force. The bulb should not be deformed. The thermostat casing is mounted to the control panel by two screws.
