pressure difference switches
standard adjustment rante of pressure difference: 1 - 20 psid, make/break differential - spst; 3 - 9psig, max system pressure (psig) : 50, max pres (psib) ; 80, bellows diameter 1 - 3/8", 222-32 series switch is intended for use on vessels having an annunciator panel (spec. MIL-A-17196) with a supervisory circuit continuously indicating whether ships wiring between the panel and the alarm switch is in working order. to provide for this feature a NAVY-Approved resistor is connected across the terminal screws. this resistor is easily removed when the switch is used on panels w/o this supervisory circuit.available in NON-Magnetic (brass) models when specified (less than 2.0 magnetic premeability) .
