Pressure Switches & Sensors

Ex-VCM / Ex-VNM Negative Pressure Switches

FEMA negative pressure switches detect the pressure difference relative to atmospheric pressure. The "zero" reference point on the scale of the unit corresponds to the relevant atmospheric pressure.

Overview

Ex-VCM / Ex-VNM Negative Pressure Switches detect the pressure difference relative to atmospheric pressure. All data relating to the switching pressure ranges and thus also the scale divisions on the switching devices are to be understood as the difference in pressure between the releant atmospheric pressure and the set switching pressure. The "zero" reference point on the scale of the unit corresponds to the relevant atmospheric pressure.It comes with robust housing made of seawaterresistant die cast aluminium GD Al Si 12.

Features & Benefits:
  • The Ex-VCM and Ex-VNM series are calibrated for falling pressure.
  • This means that the adjustable switching pressure on the scale corresponds to the switching point at falling pressure.
  • The reset point is higher by the amount of the switching differential.
Certifications:
  • SIL2 according IEC 61508-2
  • IBExU12ATEX1040 according to ATEX 2014/34/EU
  • IECEx IBE 14.0077
