Temperature sensors are a popular and prevalent type of sensor due to their reliability, ease of deployment, and relatively low cost. A wide variety of temperature sensors have been developed and utilized over the years for various applications. 3455RC 70870487 is one such temperature sensor with an interesting application field and working principle.

The Application Field

3455RC 70870487 is a mechanical temperature sensor that is mainly used as temperature sensing and control in HVAC systems. It is designed for installation with a thermal switch in a boiler system, and it is suitable for applications including automatic hot water control and temperature settings. The thermal switch helps to regulate the temperature by controlling the flow of hot water through the boiler, while the 3455RC 70870487 helps to measure the temperature. By utilizing the sensor\'s reference temperature detection capabilities, it is possible to accurately adjust the temperature settings of the thermal switch, providing improved comfort and energy efficiency.

The Working Principle

The working principle of the 3455RC 70870487 sensors is based on the bimetallic principle. Two thin metallic strips or foils – typically copper and zinc – are bonded together and form a memory alloy. As these strips are heated, the copper strip contracts while the zinc strip expands, resulting in a curved shape. This curved shape can then be used to move a mechanical linkage or actuate an electrical switch.

The temperature threshold of the 3455RC 70870487 is set by adjusting a calibration dial on the sensor. As the temperature rises, the bimetallic strip changes shape, actuating the switch. At the same time, the dial can be used to adjust the calibration of the sensor to ensure accurate temperature readings. When the temperature falls below the pre-set threshold, the switch reverts to its starting position.

Conclusion

The 3455RC 70870487 is an effective mechanical temperature sensor that can provide accurate readings for temperature sensing and control in HVAC systems. It is based on the bimetallic principle and is easily adjustable via a calibration dial. With its easy installation and relatively low cost, it is an ideal choice for a variety of temperature sensing and control applications.
