Fema VCMV095 pressure switch

Fema VCMV095 pressure switch 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.

Honeywell VCMV095 pressure switch technical data:

• Setting range: -0.9-0.5 bar
• Switching differential: 90-400 mbar
• Maximum working pressure: 3 bar
