A fluid is encapsulated in a metal tube (bulb and capillary) and when the temperature changes the fluid either expands or contracts.
What is inside of capillary thermostat?
In capillary thermostats, the temperature sensor consists of a capillary tube, a diaphragm and an expansion fluid. When the sensor is heated, the liquid fluid heats up and expands. The expansion of the fluid increases the pressure in the closed circuit system.
How does a hydraulic thermostat work?
Hydraulic thermostats use what is known as a “thermally expansible fluid.” This is a highly reactive fluid that swells as the heat rises and shrinks as the heat falls. This fluid is contained within a capsule inside the thermostat, and a light metal rod is extended into the capsule.
How does a remote bulb thermostat work?
These temperature controls have a capillary tube and sensor that monitor and regulate the temperature of the ambient air, a liquid, or a gas at a distance away from the control. The sensing element is not affected by changes in barometric pressure or cross-ambient conditions to ensure accurate temperature regulation.
How does a thermostat work physics?
In a thermostat, the bimetallic coil is fastened firmly at one end. The other end is free to move. Its motion, as the temperature changes, can be used to control your furnace. For example, if the coil tightens as it cools, the free end can curl toward a metal contact that starts the furnace.
How do you install a capillary thermostat?
Bulb and capillary thermostats have a fluid filled bulb and respond quickly to change in temperature. When temperature rises the bulb fluid expands via the capillary tube to an expandable diaphragm or bellows to open or close the contacts.
How does a capillary thermostat work?
Capillary thermostats are used to control heating elements. Based on the set temperature, the sensor closes as the temperature rises and opens as the temperature falls.
What is a thermostat capillary tube?

What is a thermostat made of?
An electromechanical thermostat typically contains either a bi-metal coil or a metal strip. When the temperature changes, this coil or strip will move, causing a vial containing mercury to tip to one side. The mercury flows to one end of the vial, signaling that the heating or cooling needs to be turned on.
What happens inside a thermostat?
Mechanical thermostats regulate heat thanks to the expansion of their internal metallic strips. This strip carries electricity through the connected circuit, switching on the heating. As the strip heats up, one of the metals expands enough to open the circuit and switch off the heating, cooling the room down.
What are liquid thermostat called?
LIQUID EXPANSION THERMOSTAT. The liquid expansion thermostat is generally called capillary thermostat.
What is inside a thermostat bulb?
Bulb and capillary thermostats have a fluid filled bulb and respond quickly to change in temperature. When temperature rises the bulb fluid expands via the capillary tube to an expandable diaphragm or bellows to open or close the contacts.
