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-flexible pressure transmitter programme covers different 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.
