Data Sheet

Pressure transmitter Type MBS 5100 and MBS 5150

For marine applications

The ship approved high accuracy block pressure transmitter is designed for use in almost all marine applications. MBS 5150 with integrated pulse snubber is designed for use in marine applications with severe medium inuences like cavitation, liquid hammer or pressure peaks and oers a reliable pressure measurement, even under harsh environmental conditions.

The transmitters can be easily mounted directly on the MBV 5000 block test valve or the threaded pressure connection can be used.

The exible pressure transmitter programme covers a 4 – 20 mA output signal, absolute or gauge (relative) versions, measuring ranges from 0 – 4 to 0 – 400 bar.

Excellent vibration stability, robust construction, and a high degree of EMC / EMI protection equip the pressure transmitter to meet the most stringent marine requirements.

Application

Application and media conditions for MBS 5150

Figure 1: MBS 5150

Application

Cavitation, liquid hammer and pressure peaks may occur in hydraulic systems with changes in ow velocity, e.g. fast closing of a valve or pump starts and stops. The problem may occur on the inlet and outlet side, even at rather low operating pressures.

Media condition

Clogging of the nozzle may occur in liquids containing particles. Mounting the transmitter in an upright position minimizes the risk of clogging, because the ow in the nozzle is limited to the start-up period until the dead volume behind the nozzle orice is lled. The media viscosity has only little eect on the response time. Even at a viscosities up to 100 cSt, the response time will not exceed 4 ms.
