Pressure transmitter for air and water applications
Type MBS 1900
The pressure transmitter MBS 1900 is designed
for use in air and water applications like Booster
Pumps and Air Compressors.
The semi-exible pressure transmitter
programme covers dierent output signals,
absolute or gauge (relative) versions, measuring
ranges from 0 – 4 bar to 0 – 25 bar and a wide
range of pressure and electrical connections.
Enclosure material is stainless steel AISI 316L.
