The DPA series pressure sensor is a gauge type pressure sensor for non-corrosive gases, with a measurement range of DPA01: -100kPa ~ 100kPa, DPA10: -100kPa ~ 1,000kPa. The output type is NPN output + 4 ~ 20mA; P: PNP output + 4 ~ 20mA M: NPN output + 1 ~ 5V; Q: PNP output + 1 ~ 5V. The pressure port type is P: Outer hole PT 1/8, inner hole M5; N: Outer hole NPT 1/8, inner hole M5; G: Outer hole G 1/8, inner hole M5.
This manual covers safety precautions, installation steps, wiring diagrams, and the basic specifications of the Delta DPA series pressure sensors. It explains how to connect power, signal and pressure ports, and details the supported output types and voltage ranges.
The document also describes the three operation modes (simple, hysteresis, window), parameter setting procedures, copy‑slave/master functions, and display code definitions. Accessories such as panel and bracket kits are listed, and contact information for updated versions is provided. This manual is written in Chinese.
