Working Principle of the LF55 Pressure Switch

The LF55 operates based on a mechanical principle involving spring tension adjustment. By turning the screw, users can modify the spring force, which directly impacts the switching point. Here’s how it works:

  1. Spring Adjustment: Tightening the screw increases spring tension, raising the pressure threshold for activation.
  2. Pressure Sensing: The pressure bellows or diaphragm deforms under external pressure, triggering mechanical movement.
  3. Contact Switching: When the pressure reaches the set point, the contacts close or open, altering the circuit’s conductivity.

This mechanism ensures the device can automatically regulate systems in applications like reverse osmosis, where maintaining precise pressure levels is critical.
