The compact pressure transmitter,

type MBS 3000, is designed for use in industrial

and hydraulic applications, and oers a reliable

pressure measurement, even under harsh

environmental conditions.

The compact heavy duty pressure transmitter

MBS 3050 with integrated pulse-snubber is

designed for use in hydraulic 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 exible pressure transmitter programme

covers dierent output signals, absolute or

gauge (relative) versions, measuring ranges

from 0 – 1 to 0 – 600 bar. A wide range of pressure

and electrical connections are available.

Excellent vibration stability, robust construction,

and a high degree of EMC/EMI protection equip

the pressure transmitter to meet the most

stringent industrial requirements.

Technical data

Application and media

conditions for MBS 3050

Pulse-snubber

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 when a

pump starts and stops.

The problem may occur on the inlet and outlet

side of the application, 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.
