Data Sheet

Pressure transmitter Type MEP

For use in mobile hydraulic, industrial hydraulic and air compressor applications

MEP 2200 and MEP 2250 versions:

• For use in mobile hydraulic applications

• Dual output

Output 1: Switch output

• Hysteresis 1% FS

• Time constant 1 ms

Output 2: Analogue output

• Ratiometric or absolute voltage output

MEP 2600 and MEP 2650 versions:

• For use in mobile hydraulic, industrial hydraulic and air compressor applications

• Single output

Output 1: Switch output

• Hysteresis 1 – 8% FS

• Time constant 8 – 512 ms

• Immunity towards VFD

The series are available in 2 versions:

• MEP 2200, MEP 2600 – without integrated pulse-snubber

• MEP 2250, MEP 2650 – with integrated pulsesnubber

The integrated pulse-snubber oers a high degree of protection against cavitations and liquid hammer. The well thought out design results in excellent vibration stability and an exceptional robustness. The high degree of EMI protection equips the electronic pressure switch to meet most requirements.

Application

Figure 1: Pulse-snubber

The pulse-snubber protects the sensor element in the event of cavitation, liquid hammer and pressure peaks, which may occur in liquid lled 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. The media viscosity has only little eect on the response time.

Even at viscosities up to 100 cSt, the response time will not exceed 4 ms.
