Low cost pressure switches ATEX certified

Low cost pressure switches ATEX certified
A range of compact, low cost pressure switches are now available that are ATEX-certified for use in Zone 0, Zone 1 and Zone 2 gaseous atmospheres. The new 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, including aggressive media, in hazardous environments. The switches can be used to monitor fluid levels and filters, as well as excessive or inadequate pressure and pressure differentials in closed systems.

The explosion-proof pressure switches are ideal for a range of explosive atmosphere environments, including nuclear, oil and gas, chemicals, pharmaceuticals, sewerage and food processing. The switches are available in a factory-set version, in which the pressure setting and switching differential are set by the manufacturer, or an adjustable version, the 901 Prescal, where the customer uses a scaled adjustment knob to alter the trip and reset pressure, without having to use a screwdriver. 

A wide range of switch options are available, including pressure connections in various materials, shapes and sizes. Customers can also select from a diverse range of materials for seals and diaphragms. All switches are intrinsically safe and have been categorised as Temperature Class T4 and Explosion Group IIB or IIC.
