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 oers 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 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.

Pulse-snubber

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.

Technical data

Performance (EN 60770)

Pressure measurement

Accuracy (incl. nonlinearity, hysteresis and repeatability) ± 0.5% FS

Thermal zero point shift <± 0.15% FS/10K

Thermal span shift <± 0.15% FS/10K

Response time liquids (10 – 90%) > 0.5 ms

Durability, P: 10 – 90% FS >10 × 106 cycles

Temperature measurement

Accuracy @ 20 °C ± 0.5% FS

TEB - 20 – 80 °C ± 3.0% FS*

* As the temperature is measured on the thinlm element, the true response to uid temperature depends on the installation

details, such as the "bulk metal" surrounding e.g. manifold.
