Differential pressure switch H100K-545

Pressure range: 5-50PSID 0.3-3.4 bar

Other parameters: non explosion proof, Buna-N rubber diaphragm and sealing O-ring, 1/8'NPTF epoxy aluminum coating pressure interface,

Pressure: The switch can work normally at this pressure without damaging the components and maintaining repeatability.

Voltage resistance: Occasional occurrence of this high pressure will not cause deformation of the components, but the switch needs to be recalibrated.

Work pressure: Within this pressure range, switches can be operated to maintain the set point without drifting.

A single pole double throw (SPDT) output; NEMA 4X shell, epoxy coating; Internally adjustable with reference scale.

Debugging method

1. Connect the multimeter to the output wire;

2. Unscrew the screws on top of the controller;

3. Increase the positive and negative pressure difference to 0.15 MPa, which can be read from a standard pressure gauge;

4. Loosen the fastening screw;

5. Use a straight wrench to turn the hexagonal groove inside the set value adjustment screw clockwise, increasing the set value until the switch contact switches at 0.15MPa;

6. Adjust the pressure of the calibration table to fluctuate back and forth around 0.6 MPa, and check if the pressure drops to 0.15 MPa. This value is the lower switching value to be set. The corresponding upper switching value is between 0.16-0.17MPa;

7. Tighten the set screw.

8. Debugging completed
