The Model 1210 digital pressure switch combines thin-film sensor technology with modern microprocessor electronics to provide accurate pressure switching, says the manufacturer. The design offers a four-digit LED digital display, a programmable hysteresis window and setpoints, and either a relay or NPN open collector switch output. Analog output is available on special orders. The standard unit comes with a 1¼4-18 NPT pressure port for ease of installation, the company says. The switch operates on all voltages from 12 to 32 vdc. Advanced Custom Sensors, Inc.
