The Rosemount 3051S Electronic Remote Sensor (ERS) System is a flexible, 2-wire, 4-20 mA HART architecture that calculates differential pressure (DP) using two pressure sensors that are linked together digitally.

Ideal applications for the Rosemount 3051S ERS System include tall vessels and distillation columns that have traditionally required excessive lengths of impulse piping or capillary.

Key Specifications

● Reference Accuracy = ±0.025% of span
● Measured variables = DP, P-Hi, P-Lo, Scaled Variable (level or volume)
● 4-20 mA HART Output
● Max cable length = 150 feet (45 meters)

Easily instrument high temperature processes

● Expand direct-mount capabilities for temperatures up to 410°C (770°F)
● Avoid the headaches of additional impulse piping for cooling

Improve response time in extreme temperature applications

● Prevent DP level capillary systems from becoming unresponsive
● Enhance response time by 46% over single fill fluid systems
● Measure reliably at ambient temperatures down to -75°C (-103°F) without the need for heat traced capillary systems

Simplify installation and reduce cost

● Eliminate heat tracing and routine maintenance costs
● Remove impulse piping and decrease installed cost
