MBS 3300 marine approved general purpose pressure transmitters
The general purpose pressure transmitter is designed for use in almost all marine applications, and offers a reliable pressure measurement, even under harsh environmental conditions. The flexible pressure transmitter programme covers the relevant marine approvals, absolute or gauge (relative) versions, measuring ranges from 0 – 1 to 0 – 600 bar and a wide range of pressure and electrical connections.

The version consists of two series:
- MBS 3300 – without integrated pulse-snubber
- MBS 3350 – 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.
