The Robertshaw® thermostat is a product manufactured by a leading global thermostat manufacturer (Robertshaw Controls Inc.). This thermostat is a “liquid expansion type” that controls a set of electric contacts to achieve the required temperature at the heat-sensitive part of the sensor. This process is performed through a capillary tube, where a liquid with a high thermal expansion coefficient is added to a metal pipe.
