Temperature Sensors - Thermostats - Mechanical

A 3455RC 80890023 temperature sensor is a thermostat that automatically reacts to changes in temperature by switching electrical contacts. It is a mechanical device, which operates by correlating a physical property of the target environment to a physical property of the device. In other words, the sensor element of the device interacts directly with the target environment and changes its physical state accordingly.

Working Principles

The 3455RC 80890023 thermostat operates based on the principles of thermal expansion. As the temperature of the target environment increases or decreases, a thermally sensitive material expands or contracts. This expansion or contraction causes the levers or pivots of the device to move, which in turn causes the electrical contacts to open or close. Temperature is measured by means of a temperature sensitive element and is compared to the action of the spring. When the temperature rises above the pre-set point (usually adjustable between 25°C to 80°C) the spring causes the contacts to be open; when the temperature drops the thermal element moves, closing the contacts thus activating the device.

Applications

The 3455RC 80890023 temperature sensor can be used to regulate a broad range of temperatures in any environment, including indoors in homes, offices, and other commercial or industrial buildings as well as outdoors. The sensor can be used for applications across a wide temperature range, from very cold temperatures of freezing point in cryogenic applications, to very hot temperatures of a few hundred degrees Celsius. The sensor is also ideal for controlling temperature in process automation and control systems, in heating, ventilation and air conditioning (HVAC) systems, as well as in other temperature-sensitive equipment. It is commonly used to control and maintain a specific temperature, such as in refrigeration systems, food storage, pharmaceutical manufacturing, and heating systems for homes or commercial buildings.
