LFDS63 (630/631/632) series adopts high reliable transmitter for pressure measurement. The signal is processed by the back-end circuit and displayed, and the relay output is automatically controlled according to the pressure change. Designed with a full-engineering plastic case and a high-contrast LCD digital display, it enables the product to be used in various industrial applications. It provides a variety of connection modes to fully meet various specific installation requirements. Building in a variety of settings, users can adjust the working parameters flexibly and conveniently. This series of digital pressure switch have the characteristics of earthquake resistance, long life, simple operation, strong stability, and clear display.
