Emerson Rosemount 2088 Pressure Transmitter
Product Description
With the Rosemount 2088 Gage and Absolute Pressure Transmitter, you can keep on schedule with a quick and easy-to-install solution. This transmitter features a Local Operator Interface (LOI) that has easy-to-use menus and built-in configuration buttons, so you can commission the device on the spot without complicated tools. This pressure transmitter is also available with manifolds and remote seals.
1. The 2088 pressure transmitter is available with a wide range of options to provide solutions for virtually any application.
2. The 2088 can be calibrated to ranges as low as 0 to 1.5 psi (0.1 bar) and as high as 0 to 4000 psi (275.8 bar). It can also be used to measure negative pressure ranges. The 2088 measurement capabilities enable reliable use in almost any application.

CONNECTION STYLES
Direct mount and remote mount connections are engineered to meet a wide variety of measurement needs. Direct mount connections offer simple installation for mounting transmitters directly to the vessel eliminating the need for additional transmitter mounting provisions. Remote mount connections consist of a seal attached to a transmitter via capillary tube and are used in tuned or balanced systems, high temperature installations and remote transmitter mounting applications.
ERS SYSTEMS
Electronic Remote Sensor (ERS™) System provides DP Level measurements by calculating differential
pressure from individual pressure readings. This solution eliminates the need for long capillaries and heat
tracing, reducing response time by up to 90%. The sensor system is synchronized for DP calculation, easily connects with cable, and can be independently installed and serviced for simple installation and maintenance.
TUNED SYSTEMS
A Tuned-System™ Assembly measures level using capillaries with two different lengths connected to a transmitter which allows the system to compensate for temperature drift. Typically, one side of the system is directly mounted to the vessel and the other is mounted remotely via a capillary tube. This system saves time and cost during installation by eliminating additional transmitter mounting components and is a great solution for applications with short spans and high pressures.
BALANCED SYSTEMS
Balanced Systems are a reliable solution which consists of two, equal-length capillaries connected between the transmitter and seals. The system eliminates the maintenance concerns of wet or dry legs and are good for horizontal flow and indoor applications with little to no temperature variations.
REMOTE SEALS
The Diaphragm Seal System protects transmitters from hot, cold, corrosive, erosive or viscous processes. Seals are available with differential, gage and absolute pressure transmitters. Advanced welding and assembly techniques prevent weld corrosion and improve seal strength to deliver reliability and performance in the toughest applications.
THERMAL RANGE EXPANDER
Thermal Range Expander enables pressure and level measurements in high temperature processes. This seal system uses two different fill fluids, extending the operating range of the transmitter from temperatures ranging from -75 °C (-103 °F) to 410 °C (770 °F). With an improved response time of up to 46%, thermal range expanders simplify installation and reduce cost by eliminating impulse piping and heat tracing.
