美国UEB121-120防爆温度开关（US UE B121-120 explosion-proof temperature switch ）

American UE B121-120 explosion-proof temperature switch Advantages of American UE explosion-proof temperature switch UE products: ◆ Complete product range 1/ Pressure switch adjustable range from -0.1 to 62MPA 2/ Temperature switch from -50 to 538 degrees Celsius 3/ Differential pressure switch The adjustable range is from -0.1 to 3.45MPA 3/ The sensing element has three types of diaphragm, bellows, and piston 4/ There are switches for special occasions, and there are small and low-cost switches specially designed for OEM users 5/ Both fixed The dead zone also has an adjustable dead zone pressure switch 6/ Some mechanical differential pressure and temperature switches can have on-site indication 7/ There is a 2-inch pressure port anti-blocking switch and a sanitary flat diaphragm switch The product is compact and durable, Beautiful appearance and fine processing Welded stainless steel design structure Many types of pressure switches adopt welded stainless steel diaphragm or welded stainless steel bellows structure, omitting the "O" ring, this non-leakage design improves the fire performance in hazardous explosion-proof areas , while improving the pressure resistance. Working principle The mechanical temperature switch uses special silicone oil with a stable thermal expansion coefficient. After feeling the temperature change, thermal expansion and contraction occur, resulting in deformation and displacement. signal output. 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 advantagesMechanical 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. Technical parameters:
