Temperature Sensors - Thermostats - Mechanical

Thermostats, as the name suggests, are devices used to maintain and control the temperature of physical systems. These physical systems can be anything from refrigerators to air conditioners, ovens to water heaters, and so on. 2455R-99130417 is a particular type of mechanical thermostat whose application field and working principle will be explored in this article.

The 2455R-99130417 mechanical thermostat is specifically designed for applications in industrial water heating systems. It uses a bimetallic strip as the sensing element to detect temperature changes and is typically installed in the return water line of the system to monitor the water temperature. This strip is made of two different metals, usually both metals belonging to the stainless steel family, which are joined together and then bent into a curved shape. As the water temperature changes, the different coefficients of thermal expansion of the two metals cause the bimetallic strip to bend, opening or closing the switch contacts accordingly.

The 2455R-99130417 has three switch actuators located at 50°C, 55°C, and 65°C respectively. When the return water temperature is below 50°C, the switch contacts are closed. Upon reaching 50°C, the switch contacts start to open, and up until 55°C they remain open. When the water temperature exceeds 55°C, the switch contacts close again but only until 65°C is reached. Once the water temperature goes beyond 65°C, the switch contacts open and stay open until the temperature goes back down below 65°C.

The 2455R-99130417 mechanical thermostat is a cost-effective temperature monitoring device. It does not require any external power source other than for powering the switch actuators and is easy to install and maintain. It is compact in size, making it well-suited to use in tight spaces, and is designed to be highly reliable and durable in the tough conditions found in industrial water heating systems.

In summary, the 2455R-99130417 mechanical thermostat is ideal for industrial water heating applications and is a simple and cost-effective way to monitor the water temperature. It uses a bimetallic strip as the temperature sensing element and three switch actuators, located at 50°C, 55°C, and 65°C respectively, to open or close the switch contacts accordingly.
