Description

Our most popular Differential Pressure Switch is now available in a flame-proof ATEX approved package in the Series AT11910. This pressure switch combines advanced design and precision construction to make these switches able to perform many of the tasks of larger, costlier units.

For air and non-combustible compatible gases, the AT11910 Series switches have set points from 0.07 to 20 in w.c. (1.8 to 508 mm). Set point adjustment is easy with range screw located inside the switch enclosure. Series AT11910 ATEX enclosures are available in aluminum enclosures and ideal for low pressure, hazardous area applications.

Important notes for installation:

  • Cables must be fitted through 1/2″ NPT cable gland or ATEX conduit (not supplied with instrument).
  • Make sure after cabling to close tight cover and cable gland, in order to keep IP66 rating (IP65 with option OPV, overpressure relief valve).
  • Open cover only after de-energizing instrument.
  • Attention: Check local safety rules and warnings on unit and manual for a correct use of the instrument in hazardous area.

Applications: Hazardous area low pressure applications; Air conditioning refrigeration coil icing detection; defrost cycle initiation; Clogged filter detection; Variable air volume controller.
