Temperature Sensors - Thermostats - Mechanical: 3455RC 81740140 Application Field and Working Principle

Mechanical thermostats are commonly used devices that can help monitor and adjust temperatures in a variety of applications. The 3455RC 81740140 is an example of this type of device, offering users excellent reliability, quick response time, and great accuracy in various conditions. This article will provide an overview of the application fields and working principles of the 3455RC 81740140.

Application Fields

The 3455RC 81740140 is widely used in a number of industrial applications, such as in electric appliances, heating and air conditioning systems, and water tanks. Additionally, this mechanical thermostat is used in automotive and agricultural settings, and even in various medical technologies for precise temperature control. This thermostat’s accurate readings make it ideal for these types of applications.

Working Principle

The 3455RC 81740140 is a bimetal thermostat, meaning that it contains two metals that contract and expand at different rates when subjected to increasing or decreasing temperatures. The device’s commonly used bimetals are steel and manganin, and these two metals are joined together at a point between the active and passive sides. Its bimetal construction is what allows it to detect changes in temperature.

When temperatures go up, the bimetal strips expand, causing the active side’s components to separate. This motion is a result of the manganin metal expanding more than the steel. The change is detected by a switch that is connected to a contact disk, and the disk opens when temperatures reach a certain level. As temperatures go down, the metal strips contract, causing the active side’s components to move back together and close the contact disk.

The 3455RC 81740140 also includes an adjustable knob that lets users set the desired temperature. This control setting adjusts the relationship between the steel and manganin in the bimetal strip, allowing users to set a higher or lower temperature for the device to react to. As long as temperatures remain within the set range, the thermostat’s contact disk will remain open, providing power to whatever element it is controlling.

Conclusion

The 3455RC 81740140 is a reliable and accurate mechanical thermostat that can be used in many different applications. Its bimetal strip construction allows it to respond quickly to changes in temperature, while its adjustable knob enables users to set the desired temperature range. The device’s reliability and accuracy make it a great choice for temperature monitoring and control.
