Small size, High accuracy pressure control digital pressure sensor
The rectangular square type digital pressure sensor PSB series realizing small size and high accuracy digital pressure control is to increase visibility with high luminance red LED (LED height: 9.5mm) and to implement 1/1,000 high resolution, max 2.5ms response time. Also, the series is high reliability digital pressure sensor supporting various output modes and analog output (1-5VDC) scale function in order to be used in various operating environments. Moreover, the series includes connector type line-up – PSB-C in order to make easy installation and maintenance for better work efficiency.
