Data Sheet

Pressure switch
Type MBC 5000 and MBC 5100

For heavy-duty marine applications

MBC pressure switches are used in industrial
and marine applications where space and
reliability are the most important features.

MBCs are compact pressure switches, designed
according to our block design to survive in the
harsh conditions known from machine rooms
onboard ships.

MBCs have high vibration resistance and MBC
5100 features all common marine approvals.
The xed, but low dierential guarantees
accurate monitoring of critical pressures.

MBV test valves can be delivered as standard
option for MBC.

Features

• Designed for use in severe industrial,
environments

• High vibration stability

• Part of the Danfoss block system, consisting
of MBC pressure controls, MBS pressure
transmitters and MBV test valves

• MBC 5100 with all major ship approvals

• High repeatability

• Optimal compact design for machine
building purposes

• Intended for alarm indication, shut down,
control and diagnostics in many applications

- motors, gears, thrusters, pumps, lters,
compressors, etc.
