Series ES Electronic Pressure Switchis proven reliable, even in the toughest industrial applications. The switchuses a thin film pressure sensor that is rated for 10,000,000 cycles at therated load, allowing the ES to outlast mechanical switches in high cycleapplications. The switch is designed with narrow, adjustable deadbands that canbe adjusted to less than 0.5% of range with multi-turn potentiometers. Featuresinclude status light for indication of process pressure, setpoint, reset andrelay output status. Optional 3-1/2 digit LED provides local indication ofprocess pressure. The electronics are housed in a watertight epoxy coatedaluminum enclosure for additional corrosion resistance. The Series ES is idealfor pressure alarms, shutdown and control on metal stamping, presses, injectionmolding machines and other process equipment
