The compact high temperature Danfoss pressure transmitter MBS 3250 is designed for use in hydraulic applications with severe medium influences like cavitation, liquid hammer or pressure peaks and offers a reliable pressure measurement, even under harsh environmental conditions.
The flexible heavy duty pressure transmitter programme covers 4-20 mA, 0-5 V, 1-5 V, 1-6 V and 0-10V output signal, absolute and gauge (relative) versions, measuring ranges from 0-1 to 0-600 bar and a wide range of pressure- and electrical connections.
Excellent vibration stability, uniquely robust construction, a high degree of EMC/EMI protection and a high operating temperature equip the pressure transmitter to meet the most stringent industrial and hydraulic requirements.
• 4 - 20 mA, 0 - 5 V, 1 - 5 V, 1 - 6 V and 0 - 10 V output signal
• Operating temperature -40 to 125° C
• Measuring range 0 - 600 bar
• A wide range of pressure and electrical connections are available
• For use in severe industrial environments
• With pulse-snubber
Application and media conditions
MBS 3250 with integrated pulse-snubber is specially suited for hydraulic applications where cavitation, liquid hammer or pressure peaks may occur – influences that often cause a short but extreme excess of the measuring range of the transmitter.
The integrated pulse-snubber is in principle designed as a nozzle mounted in the passage between the measured medium and the pressure sensitive element of the transmitter.
Application
Cavitation, liquid hammer and pressure peaks may occur in hydraulic systems with changes in flow 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 flow in the nozzle is restricted to the start-up period when the dead volume behind the nozzle fills, and furthermore because the nozzle orifice is relatively big (0.3 mm).
The media viscosity has only little effect on the response time. Even at viscosities up to 100 cSt, the response time will not exceed 4 ms.
