Temperature Sensors - Thermostats - Mechanical

The 3450RC 81890030 is a type of temperature sensor that uses mechanical means to identify when a temperature threshold has been reached. It is commonly used for heating and cooling, and is used to trigger HVAC systems when the temperature in a given area reaches a certain point.

How Does it Work?

The 3450RC 81890030 is an electromechanical thermostat, which means it uses an electric current to power a mechanical device which detects changes in temperature. Inside the unit there is a bimetallic strip, which is an assembly of two pieces of metal that expand and contract at different rates when exposed to temperature changes. When the two pieces become unbalanced, they actuate a switch, which sends an electric signal to a heating or cooling device when the temperature threshold is crossed.

Typical Application

The 3450RC 81890030 is most often used as a temperature control for residential and commercial HVAC systems. It detects the air temperature in the space and when the set temperature is exceeded, it triggers the HVAC system to respond. The thermostat is typically located in the living area of the house, so that occupants can adjust the temperature to their comfort levels.

Benefits

The main benefit of the 3450RC 81890030 is its reliable accuracy and easy operation.The unit is simple to install and can be used with any standard HVAC system. The bimetallic strip provides reliable and accurate readings and the switch is designed to snap closed when the temperature threshold is crossed, providing an instantaneous response time. The device is also highly reliable and will not become inefficient over time.

Maintenance Considerations

The 3450RC 81890030 is low maintenance and does not require any regular servicing. However, it is recommended that the unit be tested regularly to ensure it is functioning correctly. The unit should also be protected from dust and dirt, as these can interfere with its accuracy and operation. The sensor also needs to be calibrated, as the rate at which the metal strips expand and contract will vary with temperature.

Conclusion

The 3450RC 81890030 is an electromechanical thermostat that uses a bimetallic strip to detect temperature changes. It is commonly used to control residential and commercial HVAC systems and is easy to install and use. The device is highly accurate and reliable and requires minimal maintenance, making it a great choice for temperature control applications.
