MBS 33M Pressure Transmitter

Brand: Danfoss

The standard pressure transmitter MBS 33M 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 a 4-20 mA output signal, absolute or gauge (relative) versions, measuring ranges from psi: 0 to 8,702 (kPa: 0 to 60,000, bar: 0 to 600). 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.
