US UE 400 series vacuum switch pressure switch J400-520 J400-530 J400-S126B J400-126 J400-450    J400-550 H400-S126B H400-126 H400-450 400 series vacuum switch is a multi-purpose pressure switch, especially suitable for When multiple outputs and controls are required. Two-point and three-point settings provide multiple outputs that can be used for alarm and shutdown, early warning and alarm, high/low limit and liquid level control functions. The all-weather series vacuum switch has a variety of micro switches and a variety of process interface options, so that the 400 series vacuum switch can meet various needs. due to its own characteristics. Main features: Vacuum switch has one, two or three switch outputs, which can be set separatelywithin the range of 100% of the set point.Epoxy resin shell design meets NEMA 4X requirements. Vacuum switch has a variety of diaphragms to choose from , such as 316SS, brass, nitrile rubber and TeflonVacuum switch can choose to refer to the scale or rotate the screw to adjust the set pointThe technical parameters of the UE 400 series universal multi-point output vacuum switch are as follows:. Storage temperature -54 to 71 degrees. Ambient temperature -40 to 71 degrees; when the ambient temperature changes by 28 degrees, the typical drift value of the set point is less than 1% of the full range. The set point repeatability      pressure switch: 126-376, 520-535, 540-547, 570-572, S126-S164B type: plus or minus 2% of the adjustable range; 440-457, 550-559 type: plus or minus 1% of the adjustable range; 610-614 type is plus or minus 3 of the adjustable range %.Shock resistance After 10 milliseconds, 15G shock test, the set point can be reproduced .
