Model number A-3116041
ANVER’s A-3116041 Vacuum/Pressure Differential Switches are activated when a bellows, diaphragm, or piston sensor responds to a pressure change. This response, at a pre-determined set point, actuates a single snap acting switch, converting the pressure signal into an electrical signal. Control set point may be varied by turning the internal adjustment hex. (See adjustment below.)
Adjustment of A-3116041:
Remove vacuum/pressure switch cover. Adjust set point by turning 5/8″ hex adjustment screw clockwise (in) to raise set point, or counter-clockwise (out) to lower set point. Tension on adjustment screw can be increased by tightening lock into it.
