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 dierent 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.
