Adjustment Range: 100-500 mbar
Pressure Switch Tolerance: ±15% of the set value
Maximum Working Pressure: 600 mbar
Applicable Media: Gases in gas categories 1, 2, and 3, as well as other neutral gaseous media
IV. Working Principle
When the pressure in the system is higher or lower than the rated safety pressure, the internal diaphragm in the pressure switch moves instantaneously. The connecting rod pushes the switch contact to turn the circuit on or off. When the pressure drops to or rises to the rated reset value, the diaphragm resets instantaneously, and the switch automatically resets. This process achieves precise control and protection of the system pressure.
V. Installation and Adjustment
Installation:
Ensure that the installation position of the pressure switch meets the design requirements and avoid mechanical shock and vibration.
Connect the measurement connection and circuit wiring securely and reliably.
Adjustment:
Remove the cover from the switch.
Adjust the switch to the desired set point by rotating the dial. The arrow on the dial indicates the set point.
After adjusting the set point, confirm the working status of the pressure switch and verify it using a pressure gauge.
Replace the cover to complete the adjustment.
VI. Precautions
Wiring:
The wiring must be able to withstand temperatures of 75°C, and the specifications should comply with local standards.
Operating Procedures:
Do not operate with power on to avoid damaging the equipment or causing safety accidents.
Maintenance:
Regularly check the working status of the pressure switch to ensure its normal operation.
If any faults or abnormalities are found, contact professionals for repair or replacement in a timely manner.
