The OHD3-70M provides a reliable and economical solution for many temperature sensing applications. This type of mechanical thermostat can be used in industrial, commercial, and residential applications. This type of thermostat is characterized by its accurate temperature readings and its ability to control temperature within a range of 68°F to 242°F (20°C to 120°C).

The OHD3-70M is designed with two thermally sensitive elements. The first element is an alloy element that absorbs heat to move a bi-metallic strip. This strip consists of two strips of different metals that are bonded together. The second element is a snap-acting switch, which is designed to trip at set temperatures. This switch is the primary control for the thermostat.

When the temperature rises above the set temperature, the alloy element inside the thermostat absorbs heat. This heat causes the bi-metallic strip to bend. The degree of bending varies with the temperature and the current position of the snap-acting switch. As the strip bends further, it will eventually reach the point where it trips the switch. This triggers the thermostat to activate.

The thermostat can be configured to activate a fan or a damper depending on the specific application. When the room\'s temperature falls below the set temperature, the alloy element will release its heat and cause the bi-metallic strip to straighten. This action releases the snap-acting switch, returning the thermostat to the off position.

The OHD3-70M is suitable for applications that require accurate and reliable temperature control. It is a mechanical temperature control device that is simple to use and adjust. Therefore, it is ideal for temperature control and positioning systems, such as in gas and water heating systems, air conditioning units, and vending machines. This type of thermostat is also used in ovens, electric kettles, and other temperature sensitive appliances.

Using the OHD3-70M for temperature control offers numerous advantages over other types of thermostats. It is an accurate and reliable device, and it is easy to adjust and operate. Additionally, this type of thermostat is relatively inexpensive and requires minimal maintenance. Therefore, it is an excellent choice for any application that requires accurate temperature control.
