UE explosion-proof pressure switch J120-523 American UE pressure switch UE120 series pressure switch model: J120-190/191/192/193/194J120-171/172/173/174J120-701/702/703/704/705J120- S126B/S134B/S137B/S144B/S152B/S156B/S164BJ120-126/134/137/144/152/156/164J120-356/358/361/376J120-520/521/522/523/524/525J120-530/531/532/533/534/535J120-612/616 Application of UE120 series explosion-proof pressure switch When selecting industrial pressure, differential pressure or temperature switch, its safety performance is often considered to protect equipment and personnel security. The 120 series products meet UL, CSA, ATEX and other standards, and can meet the certification requirements of many countries and regions. They can be used in explosive areas and environments containing strong corrosive gases to protect the safety of equipment and personnel. Some technical parameters of 120 series UE switches are as follows: . Storage temperature: -54 to 71 degrees; -17 to 71 degrees; 820E type, 822E type: -40 to 71 degrees for every 28 degrees of ambient temperature change, the typical drift value of the set point is less than 1% of the full range, and the drift value is less than 2% for E121 and E122 models;.Set point repeatability: temperature switch: plus or minus 1% of the adjustable range; pressure switch: 50-55, S50B-S55B, 126-164, S126B-S164B, 171-174, 270-274, 358-376 , 520-535, 560-564, 701-705 and other models are plus or minus 1% of the adjustable range; 450-559 models are plus or minus 0.5% of the adjustable range; 36-39, 183-194, 483-494, 565-567, 612-680 and other models are plus or minus 1.5% of the adjustable range; . Shock and vibration resistance shell: after 10 milliseconds, 15G shock test, the set point can be reproduced; after 2.5G, 5-500HZ vibration After experimentation, the set point can be reproduced; aluminum alloy die-cast housing; epoxy resin coating; The E model has an anti-misuse airtight aluminum dial box cover; aluminum alloy nameplate;(responsible editor: )
