WDPS44 / Fluid DP Switch, Range 40-400kPa, DB 10±5kPa, G1/4″

WDPS Adjustable Fluid Diff. Pressure Switch/Alarm

The WDPS Pressure Switch provides a reliable way to monitor differential pressure in fluid systems. This device works perfectly for pumps, chillers, and industrial piping. It tracks the difference between high and low-pressure sides with great accuracy. Most engineers choose this model to protect equipment from low flow or high-pressure drops. It delivers the consistency needed for high-performance building automation and industrial safety.

This model handles a maximum static pressure of 16 bar. This high limit makes it suitable for demanding commercial water systems. It operates safely in medium temperatures from -10°C up to 70°C. The housing consists of hydrolysis-resistant nylon. This material is flame retardant to UL94V-0 standards. Because of its durable design, it requires very little maintenance.
