Pressure automatic control switch and pressure sensor that can change the set pressure value as needed. 【Features】 ■ Equipped with a single-pole double-throw contact, it provides two control signals for ON-OFF at both the upper and lower limits of the set pressure, allowing for changes to the set pressure value as needed. ■ Waterproof pressure switch (equivalent to IP54). ■ Uses a highly sensitive rubber diaphragm as the pressure detection element, capable of detecting minute pressures from 0.1 kPa. ■ Optimal for liquid level control. ■ The electrical opening and closing mechanism ensures reliability through a sensitive snap-action mechanism, and due to its simple design with minimal cumulative error, it has a highly sensitive structure that meets the demands for high accuracy and long lifespan in pressure control detection applications. *For more details, please contact us or download the PDF materials.
