The DP-101A-N is a multi-function dual display digital pressure sensor designed for low-pressure gas measurement applications. It features a compound pressure type design that eliminates the need for sensor settings when switching between positive and negative pressure, with a rated pressure range of -100.0 to +100.0 kPa. The sensor delivers high performance with a resolution of 1/2,000 (0.1 kPa display resolution), response time of 2.5 ms (variable up to 5,000 ms), temperature characteristics of ±0.5% F.S., and repeatability of ±0.1% F.S. It includes PNP open-collector transistor comparative outputs, NPT 1/8 male thread pressure port, and a dual 3-color alphanumeric display with 12 segments for improved visual checking. The sensor is ideal for applications such as confirming suction of electronic components, air-leak testing for PET bottles, and checking reference pressure in industrial automation and quality control systems.
