UE防爆开关J120-270-1010双刀双掷压力开关（UE explosion-proof switch J120-270-1010 double pole double throw pressure switch ）

Related terms of UE explosion-proof switch J120-270-1010 double pole double throw pressure switch Accuracy: the value indicating the accuracy of the equipment, including linearity, tolerance, hysteresis, repeatability, etc. At present, the highest precision of Nagano's pressure switch can reach ±0.5%FS, and the model is CB33. Maximum pressure (Max.P): the maximum value of the pressure range. Full Scale (FS): The difference between the maximum and minimum values ​​of the pressure range. Connection difference (dead zone): It refers to the difference between the switch setting action value and the reset value. For example, when the set value is 1MPa and the actual reset value is 0.9MPa, the connection difference is 0.1MPa. Working temperature: refers to the temperature range in which the internal mechanism and sensitive components of the instrument will not undergo continuous deformation during operation. Generally, the recommended operating temperature range of the pressure switch is -5~400C. If the temperature of the medium is too high, it can be considered to add an accessory siphon (filling shape) to achieve the purpose of cooling. SPDT (Single Pole Double Throw): Consists of a normally open, a normally closed contact and a common terminal. DPDT (Double Pole Double Throw): It consists of a symmetrical left and right common terminal, and two sets of normally open and normally closed terminals. Explosion-proof pressure switch overview The explosion-proof pressure switch uses a high-precision pressure sensor as a detection element, uses a high-stable circuit to generate a switch signal, and realizes continuous pressure measurement and switch control. It has the advantages of high precision, small hysteresis, fast response, stable and reliable performance, small size, easy operation and simple and flexible installation. 0140 Gold contacts M201 factory setting, need to specify the rising or falling setting The M277 nameplate uses kPa or MPa as the pressure range unit, factory selected. not suitable for temperature switches M278 uses kg/cm2 as the pressure unit on the nameplate, not applicable to temperature switches M405 complies with European ATEX intrinsically safe standards M406 complies with the Russian Gosgortechnadzor flameproof intrinsically safe standard M421 explosion-proof junction box, only suitable for Russian explosion-proof standards M423 ATEX Compliant Flameproof Junction Box M430 Lid lock M444 Paper Signs M446 stainless steel tag M460 external grounding screw; for non-metallic piping systems (ATEX installations) M480 differential pressure switch type K, 316 stainless steel pressure port, sensor material cannot be changed.
