Data Sheet
Differential pressure switch
Type MBC 5080 and MBC 5180
Heavy duty industry and marine applications
MBC dierential pressure switches are used in
industry and marine applications where space
and reliability are the most important features.
MBCs are compact pressure switches, designed
according to our new block design to survive in
the harsh conditions known from machine
rooms onboard ships.
MBCs have high vibration resistance and
feature all commonly marine approvals.
Features
• Designed for use in severe marine and
industrial environments
• High vibration stability
• Part of the Danfoss block-system, consisting
of MBC pressure switches, MBS pressure
transmitters and MBV test-valves
• MBC 5180 with ship approvals
• Low xed hysteresis and high repeatability,
• Optimal compact design for machine
building purposes
• Intended for alarm indication, shut-down,
control and diagnosing in many applications motors, gears, thrusters, pumps, lters,
compressors etc.

Dierential pressure switch, type MBC 5080 and MBC 5180
Mechanical connections
Mechanical dierential
MBC standard versions are adjusted at minimum dierential range 0.3 bar.
Variation in the system pressure will not aect the dierential setting.
If the dierential is set to a high value at 0 bar system pressure, there will be a small change in the setpoint.
Example:
MBC 5080 and MBC 5180 set to 5.0 bar dierential at 0 bar system pressure will at 30 bar system pressure give alarm
at approx. 34.2 bar. Dierential decreased 0.8 bar.
Our experience is that MBC 5080 and MBC 5180 often are used at a dierential setting close to minimum, where the
dierential would be independent of the system pressure.
If a high dierential is needed, we recommend to make a dierential setting at the system pressure that is normal
for the application.
