Profile: Pressure Switches, Inc. specializes in engineering & manufacturing of pressure switches for both the airborne and industrial markets. The series 1 differential pressure switch is for high pressure and low pressure requirements. Series 1 pressure switch is for low and very low pressure requirements, using a sensitive diaphragm sensor with a very narrow deadband. The series 6 pressure switch is a highly reliable pressure switch for tough applications. Its precision machined aluminum body is anodized for maximum corrosion protection. A polyimide film diaphragm operates a field adjustable switch trip point mechanism attached to a long mechanical life, sensitive differential snap-switch (es). It is ideal for hazardous locations. Pressure ports are available in either anodized aluminum or stainless steel. This series offers pressure ranges from 3 inch WC to 5000 psi.
