A temperature sensor is a device that is used to measure and monitor temperature changes in our environment. A thermostat, on the other hand, is a device that is used to control temperature by detecting temperature levels in the environment. The 3455RM 81700009 is a type of combination of temperature sensor and thermostat that is designed specifically for monitoring and maintaining certain temperature levels in a particular environment or location.

The 3455RM 81700009 temperature sensor and thermostat run on the principle of mechanical operation.

The main components of this device are a thermistor, an expanding bimetal, and a heat-sensitive contact. The thermistor is a semiconductor component that is sensitive to temperature changes and is responsible for detecting temperature levels and providing the appropriate signals to the bimetal. The bimetal is a strip of two metal materials with different temperatures coefficients that expand or contract to vary its shape due to heat or cold. This is used to act as a switch in the device which opens and closes the circuit when certain temperature limits are reached.

The heat-sensitive contact is a material that changes its electrical properties when in contact with heat. It is used as a signal device that is in constant contact with the thermistor to provide a current that opens and closes the circuit.

When the device is exposed to temperatures higher or lower than the pre-set limits, the thermistor detects the changes in the environment and initiates the sequence of events for activating or deactivating the circuit. The changes in temperature causes expansion or contraction of the bimetal which leads to the opening or closing of the circuit, respectively. The heat-sensitive contact provides the current to the thermistor for maintaining the open or closed state of the circuit.

The 3455RM 81700009 temperature sensor and thermostat is highly accurate and reliable and can be used for both home and industrial applications. This device is particularly well suited for controlling temperatures in refrigerators, air conditioners, and other heating and cooling systems. This device can also be used for monitoring and maintaining temperature levels in laboratories, greenhouses, food storage, and anywhere where accurate temperature control is necessary.

In conclusion, the 3455RM 81700009 temperature sensor and thermostat is a highly efficient device that uses the principle of mechanical operation and is designed for accurately monitoring and maintaining temperature levels in a variety of situations. This device offers a reliable and accurate solution for temperature monitoring and control in both residential and industrial applications.
