Temperature Sensors - Thermostats - Mechanical - 2455R90140921 Application Field and Working PrincipleTemperature Sensors are instruments or devices used to detect and measure temperature. They work by converting a temperature-dependent physical property into a electrical signal, and are used in various fields of technology, engineering, and science. Thermostats, in particular, are temperature sensors used to regulate the temperature of a system. Mechanical thermostats are temperature sensors that are operated with a mechanical mechanism instead of electricity. The 2455R90140921 thermostat is a mechanical thermostat designed for cold temperature applications such as refrigerators, freezers, and other cold appliances. The thermostat can accommodate temperatures from -18 to 6°C and will activate a cooling system when the temperature rises above a preset limit. The 2455R90140921 thermostat has no power requirement, as the contacts are operated mechanically without the need for an external supply. The 2455R90140921 operates using two bimetallic strips, one exposed to the environment and one in a protective container. Temperature changes cause the two strips to move differently, as the one exposed to the environment expands or contracts faster than the other. This causes them to move away from each other, arming the thermostat and activating a relay. If the temperature rises to the preset level, the two strips move together, disengaging the relay switch.The 2455R90140921 can be used with most standard wall outlet and relay switches. When installed, the thermostat is set to the desired temperature, using a small adjustment knob located on the outside of the device. The adjustment knob is connected to a spindle that is linked to the mechanical bimetallic strips mentioned. Turning the knob will cause the two strips to move either closer or further apart. The 2455R90140921 is a great solution for controlling temperature in cold applications. The thermostat’s mechanical design ensures reliable operation, and its flexibility lets it work effectively with most standard wall outlet and relay switches. The thermostat is very easy to set, as it only requires a simple adjustment to calibrate. Furthermore, the 2455R90140921 requires no outside power source, making it an ideal low-cost solution for cold temperature applications.
