1 Pressure transmitters for high temperature marine applications Type MBS 3300 and MBS 3350 Technical brochure

2 Features Designed for use in severe maritime environments For medium and ambient temperatures up to 125 C Low supply voltage All standard output signals: 4-20 ma, 0-5 V, 1-5 V, 1-6 V, 0-10 V Enclosure and wetted parts of AISI 316L A wide range of pressure and electrical connections Temperature compensated, linearized and laser adjusted Description The compact high temperature pressure transmitter MBS 3300 and MBS 3350 are designed for use in almost all marine applications, and offers a reliable pressure measurement, even under harsh environmental conditions. The flexible pressure transmitter programme covers different output signals, absolute and gauge (relative) versions, measuring ranges from 0-1 to bar and a wide range of pressure and electrical connections. A robust design, an exellent vibration stability, and a high degree of EMC/EMI protection equip the pressure transmitter to meet the most stringent marine requirements. MBS 3350 Application and media conditions Application Cavitation, liquid hammer and pressure peaks may occour in hydraulic systems with changes in flow velocity, e.g. fast closing of a valve or pump starts and stops. The problem may occour on inlet and outlet side, even at rather low operating pressures. Media condition Clogging of the nozzle may occour in liquids containing particles. Mounting the transmitter in an upright position minimizes the risk of clogging, because the flow in the nozzle is restricted to the start-up period when the dead volume behind the nozzle orifice is relatively big (0.3 mm). The media viscosity has only little effect on the response time. Even at a viscosities up to 100 cst, the response time will not exceed 4 ms.
