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.

Features

• Designed for use in air and water applications.
• Wetted parts of stainless steel (AISI 304).
• Pressure ranges in relative (gauge) or absolute from 0 – 25 bar.
• Output signals: 4 – 20 mA, or ratio metric.
• Absolute or relative (gauge) sensor element.
• A wide range of pressure and electrical connections.
• Digitally compensated.
