US UE temperature switch 107 series Application Guide  Mechanical temperature switches are widely used in various pipelines and tanks. UE mechanical temperature switches are used for interlock protection of important dangerous equipment due to their excellent reliability. Such as the temperature control of the lubricating oil tank or the temperature control of the pipeline. It involves a wide range of industries, such as electric power, petroleum refining, offshore platforms, oil pipelines, chemical industry, environmental protection, metallurgy, pharmaceuticals and many other industries.  Measuring principle  The principle of the UE mechanical temperature switch is the same as that of the pressure switch. 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. Finally start the micro switch at the top to make the electrical signal output. 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 of UE mechanical temperature switches: 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 capillary length of the standard configuration of the mechanical temperature switch is 1.8m, which can be extended according to different requirements of customers, up to 15m. The  characteristic  set point repeatability. The adjustable range of the temperature switch is ±2%. The pressure switch is 530-535; %; 610-614 is the ±3% of the adjustable range Shock resistance The set point can be reproduced through the 15G, 10 millisecond cycle test Anti-vibration After the 2.5G, 5-500HZ vibration test, the set point can be reproduced The housing is die-cast aluminum Alloy, epoxy-coated housing, sealing gasket, captive screw housing rating Add option M900 to meet NEMA 4X, IP65 requirements Switching Outputs One, two or three single pole double throw (SPDT) can be individually set throughout the range, can be connected as "normally open" or "normally closed"  electrical rating 15 amps, 125/250/480VAC ( DC reference table 5)  Electrical interface Three 7/8" diameter punching holes for fixed installation 2  -  ф8.4 holes on the back, eye distance 63.5mm Limits; temperature bulb and capillary 6 feet 304 stainless steel  temperature dead zone Under experimental conditions, typical values ​​are 1% of set point range for Type F switches and 2% for Type E switches  Design Standards UL; CSA; FM  B117 Series  B117-119, B117-120, B117-121; E117  series  E117-1BS, E117-2BS, E117-3BS, E117-4BS, E117-5BS, E117-6BS, E117-7BS, E117-8BS;  E117 -2BSA; E117-2BSB;
