美國UE機械式防爆溫度開關C120-120（American UE mechanical explosion-proof temperature switch C120-120 ）

American UE mechanical explosion-proof temperature switch C120-120 American UE mechanical explosion-proof temperature switch working principle The mechanical temperature switch adopts special silicone oil with stable thermal expansion coefficient, which will expand with heat and contract with cold after feeling the temperature change, resulting in deformation and displacement. Through mechanical structures such as railing springs, the uppermost micro switch is finally activated to output electrical signals. Classification UE mechanical temperature switches are further divided into two categories: local in-line mechanical temperature switches and remote capillary mechanical temperature switches. Mechanical temperature switches are divided into brass and stainless steel according to different temperature measuring elements. Technical advantages Mechanical temperature switches have the high reliability of mechanical switches. And the output of high-capacity switching signal is also convenient for users to directly control some simple actuators. The local in-line mechanical temperature switch is easy to install and easy to fix the meter head. However, because it is relatively close to the electronic micro switch, the temperature resistance is not as high as that of the remote capillary mechanical temperature switch. In some working conditions where there is no local installation position, the remote capillary mechanical temperature switch can separate the meter head from the local temperature package, and the insertion depth is more flexible. The standard capillary length of the mechanical temperature switch is 1.8m, which can be extended up to 15m according to different requirements of customers.
