PMPSW200

This series of pressure switches is designed to meet the high-precision requirements of industrial applications and is suitable for gas and liquid pressure measurement across a wide temperature range. They are widely used in pneumatic systems, hydraulic systems, and process control engineering. The switches feature zero-point calibration and allow online adjustment of switching points via PC software. Users can also configure both the switching point and hysteresis range, with an adjustable range from 1% to 99%, offering flexible and precise control for various application needs.

Product Features

Featuring high dielectric strength with a seal-less and weld-free design, this device utilizes µC-based signal processing, offers high integration density, vacuum sealing without elastomers, supports flexible customization, and allows online configuration of switching points.
