Automation Direct QPSH-AN-42 Digital Pressure Sensor

The Automation Direct ProSense QPSH-AN-42 digital pressure sensor is a combined switch and transmitter designed for industrial pressure monitoring in pneumatic and hydraulic systems. It covers a pressure range of -14.5 to 145 psig with an accuracy of ±0.3% of full scale and presents the reading on a built-in two-line, 4-digit tri-color LCD display. The device provides three outputs: two configurable switches (NO/NC) with NPN selectable, and a 4–20 mA analog output for remote monitoring. It operates from 11–26 VDC and uses a 1/8 in male NPT process connection, with a 6.6 ft (2 m) cable for flexible wiring. The QPSH-AN-42 is UL-listed and RoHS compliant, aligning with common industrial safety and environmental requirements. This model’s on-board display and multiple signaling outputs support quick local visibility and versatile integration into control systems where precise pressure readouts and multiple signaling paths are essential.
