J400-126UE单点真空开关（J400-126 UE single point vacuum switch ）

Technical parameters of 400 series pressure switches  . Storage temperature: -54 to 71 degrees;  . Ambient temperature: -50 to 71 degrees; every time the ambient temperature changes by 28 degrees, the typical drift value of the set point is less than 1% of the full range;  . Setting Point repeatability: temperature switch: plus or minus 2% of the adjustable range;   pressure switch: 126-376, 50-535, 540-547, 570-572, S126-S164B type is plus or minus 2% of the adjustable range; 550-559 Models are plus or minus 1% of the adjustable range; 610 -614 models are plus or minus 3% of the adjustable range;  Shock resistance: After 10 milliseconds, 15G shock test, the set point can be reproduced;  Anti-vibration: After 2.5 G. After the 5500Hz vibration test, the set point can be reproduced;  enclosure level: NEMA 4 requirements;  switch output: one, two or three SPDT outputs; 100% can be set separately within the adjustment range; 521- Type 524,531-534: 50%; Type 520,525,530,535,570-572: 30%;. The switch can be connected as normally open or normally closed.  Electric rating of electric shock capacity: 15A, 125/250/480VAC, the electrical switch is used for DC power supply, and the electric shock capacity will become smaller.  Weight: 3-7.5 lbs;  Electrical Connection: One 3/4NPT, two 7/8" diameter knockouts;  Pressure Connection: One 1/4" NPT on all models; except S126B-S164B models, 520- 535 type is 1/2NPT, 540-547 is 1/8NPT;  temperature components: E series uses the same components as F series, but the measuring range is limited due to the reference scale. Bulb and capillary: 6 inches long, 304 stainless steel; in-line, 120 and 121 models: nickel-plated brass, 316 stainless steel optional; Filling: 1BS type: filling solvent; 2BS-8BS: filling organic oil;  temperature dead zone: under laboratory conditions, F series is 1% of the full range, E, B&C series is 2%;  differential pressure indication: Applicable to J400K, J402K's 147-S157B type;  50% of the range is approximately 1.5%, and 3% on both sides of the endpoint; the indicator window is made of flexible glass; the indicator can be adjusted on site, and its accuracy is the set point 1% of the range.   UE switch debugging method  1. Connect the multimeter to the output wire;  2. Unscrew the screw on the top of the controller;  3. Increase the positive and negative pressure difference to 0.15MPa, which can be read from the standard pressure gauge;  4. Loosen the set screw;  5. Use a straight wrench to turn the set value adjustment screw clockwise to make the set value change from small to large until the switch contact is switched at 0.15MPa;  6. Adjust the pressure of the calibration table to change up and down at 0.6MPa, and check whether it is 0.15Mpa when the pressure drops. This value is the lower switching value to be set. Its corresponding up-switching value is between 0.16-0.17MPa; 7. Tighten the set screw.  8.
