FEMA VCM / VNM
FEMA VCM / VNM negative pressure switches or vacuum pressure switches detect the pressure difference relative to atmospheric pressure. All data relating to the switching pressure ranges and thus also the scale distributions on the switching devices should thus be interpreted as the pressure difference between the relevant atmospheric pressure and the set switching pressure. The “zero” reference point on the scale corresponds to the relevant atmospheric pressure. The pressure switches are supplied with a robust housing made of seawater-resistant die-cast aluminum. The switching differential is not adjustable on VCM pressure switches. However, the switching differential is adjustable on VCMV types. VCM and VNM pressure switches are calibrated for falling pressure. This means that the adjustable switching pressure on the scale corresponds to the switching point at falling pressure.
