Pressure switch with piston/diaphragm design

April 1, 2005
The PS41 Series of pressure switches incorporates two design principles to achieve excellent performance characteristics. PS41 switches utilize an internal piston to allow high-proof pressure, while gaining sensitivity and accuracy from a diaphragm media interface. Repeatability is ±2 percent of the full set-point range of 3 to 100 psi (0.2 to 7 bar) while delivering a 350 psi proof pressure. PS41 pressure switches are compact—the largest body is 1.25” in diameter. Typical applications include monitoring coolants in machine tools, transmissions in off-highway vehicles, and as back up to transducer-based monitoring systems.
