Potter ADPS (Adjustable Deadband Pressure Switch)
Potter ADPS is an Adjustable Deadband Pressure Switch with independent set and reset points that are adjustable throughout the entire operating range of the switch. The minimum deadband (minimum span between set and reset points) may be obtained at any point in the operating range of the switch. A change in pressure greater than the high setting will reposition the switch mechanism to open or close a single snap-action electrical switch.
