Pressure Switches & Sensors
VNM Negative Pressure Switches
VNM Vacuum Switches/ Negative Pressure Switches detect the pressure difference relative to atmospheric pressure.
Overview
VNM Vacuum Switches/ 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 relevant atmospheric pressure and the set switching pressure. The "zero" reference point on the scale of the unit corresponds to the relevant atmospheric pressure.
Certifications:- SIL 2 according IEC 61508-2
