Introduction to 3455RM 00870400

The 3455RM 00870400 is an industrial temperature thermostat from Honeywell. It is used in a wide range of applications where accurate temperature sensing and control is required. It can also be used in commercial and home applications, such as residential heating and cooling systems. The 3455RM 00870400 is a mechanical thermostat that uses a bimetallic strip to provide a temperature-sensitive switch.

Application of 3455RM 00870400

The 3455RM 00870400 is designed for applications which require accurate temperature sensing and control. It is commonly used in commercial and industrial applications to monitor and control temperatures in air-handling units, unit heaters, refrigeration systems, and other temperature-sensitive environments. It can also be used in residential heating and cooling systems, as well as other HVAC applications. It can be used to set and maintain a desired temperature for cooling or heating, as well as for monitoring and alarming when the temperature exceeds a certain threshold.

Working Principle of 3455RM 00870400

The 3455RM 00870400 uses a bimetallic strip as its temperature sensing element. This strip has two different metals bonded together, such as copper and steel. When the temperature of the environment changes, the strip will warp due to the metals expanding at different rates. This warping causes a small metal roll pin to move with the strip, thus closing a switch when the desired temperature threshold limit is exceeded. The switch will remain closed until the temperature returns below the threshold limit. The bimetallic strip also has a return spring which causes the strip to move back when the temperature decreases, thus reopening the switch and allowing the thermostat to reset.

Conclusion

The 3455RM 00870400 is a mechanical thermostat from Honeywell. It is designed for applications which require accurate temperature sensing and control, and commonly used in commercial and industrial settings. It uses a bimetallic strip to provide a temperature-sensitive switch which will open and close when the temperature rises above or falls below a certain threshold limit. This thermostat is reliable and cost-effective, and is easy to install and maintain.
