OHD1-45B is a mechanical thermostat designed for temperature measurement and control. It uses a bimetallic strip in its construction, which is composed of two different metallic strips bonded together. As the temperature of the environment changes, the two metals expand or contract at different rates, causing the strip to bend or curve. This curvature is used to control the electrical circuit that is connected to it, and ultimately to control a mechanical device such as a fan or a stepper motor to control the temperature.

The OHD1-45B has a wide array of applications, and can be used to ensure that the temperature of an environment or a machine is well maintained. Some examples of the applications of the OHD1-45B include refrigerators, air conditioners, furnaces, fireplaces, boilers, and other domestic and industrial machines or environments where temperature control is desired. It can also be used in medical devices and laboratories where accurate temperature control is required for accurate results.

In terms of its working principle, the action of the bimetallic strip is used to control the electrical circuit in the thermostat. The two metallic strips, when exposed to temperature changes, expand or contract at different rates. This enables the bimetallic strip to bend or curve, which in turn closes or opens the electrical contact inside the device. When the electrical contact is closed, the circuit is completed and the electrical signal is sent to the motor or fan to control the temperature.

To implement temperature control, the OHD1-45B is set with a pre-defined temperature. When the temperature of the environment starts to increase beyond this pre-defined level, the bimetallic strip begins to bend and contracts, thus completing the circuit and enabling the fan or motor to turn on. Similarly, when the temperature decreases below this pre-defined level, the bimetallic strip expands, opens the circuit, and the fan or motor is turned off. This process is repeated until the desired temperature is maintained.

In conclusion, the OHD1-45B is a mechanical thermostat used to measure and control the temperature of a variety of environments or machines, and it works on the principle of a bimetallic strip which bends or curves in response to changes in temperature. It has a wide range of applications and can be used to ensure a precise temperature control for a variety of applications, from air conditioners and furnaces to medical devices and laboratories.
