UEJ402-134真空表压压力开关-0.1-0.14MPa（UE J402-134 Vacuum gauge pressure switch-0.1-0.14MPa ）

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.

When the pressure drops When it reaches or rises to the rated recovery value, the disc resets instantaneously and the switch automatically resets, or in simple terms, when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, and the switch element is pushed directly or after comparison to change The on-off state of the switch element achieves the purpose of controlling the measured pressure. The elastic components used in the pressure switch include single coil spring tube, diaphragm, bellows and so on. Common models of UE J400 series mechanical pressure switches: UE J402-134 Vacuum pressure switch-0.1-0.14MPa J400 series main models and features J400 type, single point output, internally adjustable J402 type, dual point output, internally adjustable type J403 , three-point output, internally adjustable
