A thermostat is a temperature sensing and control device that is widely used to keep indoor comfort levels consistent. The 67F090-0140 is a mechanical thermostat that is used in a variety of applications. This article will discuss the application fields and working principle of the 67F090-0140.

Application Fields

The 67F090-0140 is designed to provide temperature control in a variety of applications. It is often used in residential and commercial heating, ventilation, and air conditioning (HVAC) systems. The thermostat is also commonly used in light industrial and environmental control applications.

It can also be used to control environmental indicators such as humidity, pressure, flow, and light. Additionally, the 67F090-0140 can be used in commercial refrigeration applications and the control of electrical loads such as heaters and cooling motors.

Working Principle

The 67F090-0140 uses a self-contained mechanical switch to activate and deactivate the thermostat. This switch is connected to a bi-metal meter which is calibrated to open and close the switch at different temperatures. The bi-metal meter is housed inside a case which allows the user to adjust the temperature setting. This set temperature is called the setpoint.

Once the setpoint is set, the bi-metal meter inside the case will activate the switch when the ambient temperature rises above the setpoint. This will open the circuit, causing the device to be switched off. Conversely, when the ambient temperature falls below the setpoint, the bi-metal meter will deactivate the switch, allowing the circuit to be closed. This will cause the device to be switched on.

Conclusion

The 67F090-0140 is a versatile mechanical thermostat that can be used in a variety of applications. It works by using a self-contained mechanical switch connected to a bi-metal meter that is calibrated to open and close the switch at different temperatures. This allows the user to maintain consistent indoor temperatures as desired.
