A range of compact, low cost pressure switches are ATEX-certified for use in Zone 0, Zone 1 and Zone 2.
The 901 range of ATEX-certified pressure switches, from Impress Sensors, are ideal for monitoring overpressure, vacuum or differential pressure of both liquid and gaseous substances. The switches can be used to monitor fluid levels and filters, as well as excessive or inadequate pressure and pressure differentials in closed systems.
