901..Ex ATEX Approved Factory Set Pressure switch

Introducing our advanced Pressure Switch Monitor, designed for precise monitoring of overpressure, vacuum, or differential pressure in both liquid and gaseous media, even aggressive ones. With factory-set pressure settings and switching differential, you can rely on accurate performance from the moment it’s installed. For applications requiring temperature resistance above 85°C, we offer metal or PPS pressure connections. Furthermore, we are committed to customisation, providing pressure connections of different sizes, other plastics, or brass nickel-plated options upon request. Ensure optimal safety and efficiency in your operations with our reliable and adaptable Pressure Switch Monitor.
