DANFOSS MBS 1300/1350 Series Pressure Transmitters

DANFOSS MBS 1300/1350 Series Pressure Transmitters are dual-output transmitters designed for demanding OEM hydraulic applications. Output 1 provides a pressure signal, while Output 2 provides a temperature signal. The MBS 1350 features an integrated pulse snubber to help protect the sensor against cavitation and liquid hammer. The MBS 1300, by contrast, is supplied without an integrated pulse snubber.

Performance (EN 60770)

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 thinfilm element, the true response to fluid temperature depends on the installation details, such as the “bulk metal” surrounding g. manifold.
