Rosemount 2090P Pressure Transmitter

1.General Description

The Rosemount 2090P Pressure Transmitter is a small and strong device. Manufacturers design it for demanding industries like pulp and paper, chemical processing, and wastewater treatment. The isolation diaphragm is flush with the vessel or pipe walls. This design helps reduce clogging when handling thick or sticky materials.

This transmitter measures both absolute and gauge pressure, giving flexibility across a wide range of process needs. Its small size and strong build make it perfect for tight spaces and tough job sites. This includes construction sites, landscaping projects, and industrial environments.

The 2090P also supports the HART communication protocol. This protocol sends digital data like diagnostics and process variables. It does this while keeping a 4–20 mA signal.

Users benefit from the advantages of HART communication, including frequency shift keying (FSK) for reliable transmission. This makes it easy to integrate into modern process control and control systems.

People often call the series the 2090P Emerson or Rosemount 2090. It includes the 2090PG Rosemount gauge model and the 2090PA absolute model. Both are HART-enabled for seamless monitoring and setup.
