Description: Capillary Thermostats is built for accurate and reliable-temperature control for domestic appliances and industrial equipments. It comprises of capillary tube, sensing bulb and diaphragm (phial) filled with liquid, fixed in the plated MS housing and moulded Bakelite switch base. The desired temperature could be set using a black Bakelite knob with white scale markings calibrated in °C. The thermostat work on the principle of thermal expansion, with temperature rise the expansion of liquid filling the phial causes the opening of snap action switch located in the case - a single pole single throw, normally closed circuit breaks (opens) on rise of temperature. The differential temperature of any fluid or solids heated by electricity, gas, or oil is kept constant by the instrument. It is used in washing machines, coffee vending machines, dishwashers, fryers, electric cooker, hot water appliances, industrial boilers, grills, ovens, deep fryer, cooking range, storage heater, oil burners, sterilizer roaster, dryers, oil bath, water bath incubation other domestic and industrial equipments, plastic moulding machine, kitchen equipments and laboratory instruments. These are available in three temperature ranges of 30 to 85ºC, 30 to 110ºC and 50 to 300ºC.
