3450RC 84780111

Introduction

Temperature sensors are widely used in industrial processes and control systems, as they can provide temperature measurements that are accurate and reliable. The type of temperature sensor, or thermostat, that is used varies depending on the application. But the basic principle is the same - a thermistor is used to measure the temperature and then a setpoint is set to determine when the temperature reading is too hot or too cold.

3450RC 84780111 Application Field and Working Principle

The 3450RC 84780111 is a mechanical temperature sensor that works by sensing changes in the air or liquid temperature. This type of sensor is commonly used in oil, water, and gas applications. The 3450RC 84780111 is an example of a thermistor-based temperature sensor. A thermistor is a type of resistor that, when exposed to changing temperature, produces a voltage proportional to the temperature change. When the temperature changes, the resistance of the thermistor changes as well.

The 3450RC 84780111 is a two-piece design that consists of a bimetallic strip and a spring. The bimetallic strip is made up of two strips of metal (usually copper and iron) joined together. When exposed to changing temperatures, the two metals expand and contract at different rates, which causes the strip to bend. The spring is attached to the strip and helps keep the strip in place. The spring is also connected to an adjustable contact.

When the temperature changes, the bimetallic strip bends and applies pressure to the adjustable contact. This pressure causes the contact point to move, which in turn activates a relay. The relay is connected to a temperature indicator or controller, which is then used to take the appropriate action.

Conclusion

The 3450RC 84780111 is an example of a mechanical temperature sensor. It works by sensing changes in temperature through the use of a bimetallic strip and an adjustable contact which is connected to a relay system. This type of sensor is commonly used in various industrial processes and control systems due to its accuracy and reliability.
