Designed for applications in hazardous atmospheres, PSW-400 Series Pressure Switches offer complete reliability due to a rugged, die-cast aluminum enclosure with waterproof gaskets and two separate chambers for electronics and actuator. Single or dual setpoints are available, with all critical parts made of stainless steel. In addition, the PSW-400 Series employs vibration-resistant setpoints and a calibrated scale.
