MBS 32/MBS 33 Pressure Transmitter

Brand: Danfoss
Request Information
Favorite

The standard pressure transmitters MBS 32 and MBS 33 are designed for use in almost all industrial applications, and offer reliable pressure measurements, even under harsh environmental conditions.

The flexible pressure transmitter programme covers different output signals, absolute or gauge (relative) versions, measuring ranges from 0 to 1 to 0 to 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.
