Danfoss MBC 5080, MBC 5180 Data sheet

Data Sheet
Differential pressure switch Type MBC 5080 and MBC 5180
Heavy duty industry and marine applications
MBC dierential 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.

Dierential pressure switch, type MBC 5080 and MBC 5180
Mechanical connections
Mechanical dierential
MBC standard versions are adjusted at minimum dierential range 0.3 bar.
Variation in the system pressure will not aect the dierential setting.
If the dierential 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 dierential at 0 bar system pressure will at 30 bar system pressure give alarm at approx. 34.2 bar. Dierential decreased 0.8 bar.
Our experience is that MBC 5080 and MBC 5180 often are used at a dierential setting close to minimum, where the dierential would be independent of the system pressure.
If a high dierential is needed, we recommend to make a dierential setting at the system pressure that is normal for the application.
