Temperature Sensors - Thermostats - Mechanical

Mechanical thermostats, such as B12A11525AEFA0GE, are commonly used for temperature control applications. A mechanical thermostat is a device used to measure and control the temperature of a system or environment. It consists of two main components: a temperature sensing element that senses the temperature of the system, and a switching mechanism that turns the system on or off depending on the set temperature. The temperature sensing element in a mechanical thermostat can be a bi-metal disc or a fluid-filled bellows. The switching mechanism can be a mechanical switch such as a cam-operated switch, a solid-state switch, or a mercury switch. B12A11525AEFA0GE is a split switching thermostat with a high-accuracy off-the-shelf option.

The working principle of the B12A11525AEFA0GE is based on the thermal expansion of a bi-metal disc. This disc is constructed in such a way that two different metals with different thermal coefficients of expansion are bonded together. When the temperature changes the two metals expand at different rates causing the disc to bend or flex. The switch mechanism is attached to the disc and as it flexes, it triggers the switch. The set point is determined by the positioning of the switch mechanism relative to the disc.

The B12A11525AEFA0GE can be used in a wide range of applications, such as food processing, medical device control, and automotive thermostats. It is designed to be used in both commercial and industrial environments and can be used in temperatures ranging from -20°C to 150°C. The temperature accuracy is +/- 2°C. The switching mechanism can be configured to either normally-open or normally-closed, and it is rated for a maximum current of 1 amp. The device also features a visual indication of contact status.

In summary, the B12A11525AEFA0GE is a mechanical thermostat that can be used for temperature control applications. It uses a bi-metal disc to sense the temperature of the system, and a switch mechanism to turn the system on or off depending on the set temperature. It is designed to be used in commercial or industrial environments and can operate in temperatures ranging from -20°C to 150°C.
