OEM Dual output Transmitters for heavy-duty applications, Type MBS 1300 and MBS 1350
MBS 1300 Series is a dual output transmitter. Output 1 gives a pressure signal where as output 2 gives a temperature signal. The Series consists of two versions:
• MBS 1300 – without integrated pulse-snubber
• MBS 1350 – with integrated pulse-snubber
The integrated pulse-snubber offers a high degree of protection against cavitations and liquid hammer, and the well thought
out design results in excellent vibration stability and an exceptional robustness. The high degree of EMI protection equips the pressure transmitter to meet most requirements.

Pulse-snubber in MBS 1350
Application
Cavitation, liquid hammer and pressure peaks may occur in
liquid filled 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.
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.

* As the temperature is measured on the thinfilm element, the true response to fluid temperature depends on the installation details, such as the "bulk metal" surrounding e.g. manifold.
