Pressure transmitters Type MBS 33

For industrial applications

The standard pressure transmitters MBS 33 are designed for use in almost all industrial applications, and oer reliable pressure measurements, even under harsh environmental conditions.

The exible pressure transmitter programme covers dierent output signals, absolute or gauge (relative) versions, measuring ranges from 0 – 1 to 0 – 600 bar and a wide range of pressure and electrical connections.

Excellent vibration stability, robust construction, and a high degree of EMC / EMI protection equip the pressure transmitter to meet the most stringent industrial requirements.
