1, Overview
TXK differential pressure switches can be widely used in large, medium, and small air-cooled or water-cooled chillers using plate heat exchangers, sleeve heat exchangers, and shell and tube heat exchangers for water flow control and monitoring of pump and water filter status. It is also widely used in gas detection, non corrosive media, measuring absolute pressure, and gauge pressure, and is widely used in air conditioning and clean rooms, fan and filter blowing control, fluid and liquid level control.

5, Debugging method and switch wiring diagram
Return the adjusting nut to a state of basic weakness, connect the C, NO, NC wires of the switch to the signal light. Observe the status of the signal light, connect the signal light to a green light (C is the common terminal, and when C is connected to NC at the factory, the green light will light up), and adjust the adjusting nut up and down according to the set point indicator to set it to the desired set point. (The downward pressure increases, the upward pressure decreases)
