Rosemount 3051S Electronic Remote Sensor (ERS) System

Rosemount 3051S Electronic Remote Sensor (ERS) System The Rosemount 3051S ERS System is an advanced electronic differential pressure measurement solution designed to replace traditional capillary-based remote seal systems. It uses two 3051S pressure transmitters electronically linked to provide highly accurate and stable differential pressure measurements without the limitations of fill fluids or capillary lines. The system is engineered for demanding process applications including level, flow, and pressure measurements in harsh and high-temperature environments. System Configuration for Rosemount 3051S Electronic Remote Sensor (ERS) System The ERS™ System consists of: One Primary 3051S transmitter (calculation and output) One Secondary 3051S transmitter (remote sensor) Electronic cable connection between sensors Optional remote diaphragm seals Communication protocols available: HART® FOUNDATION™ Fieldbus WirelessHART® (where applicable) Measurement Capabilities of Rosemount 3051S Electronic Remote Sensor  Differential Pressure (DP) Suitable for level, flow, and interface measurement Eliminates capillary temperature effects Static Pressure High accuracy static pressure measurement Level Measurement Ideal for tall columns, separators, and pressurized tanks Performance Specifications for Rosemount 3051S Electronic Remote Sensor (ERS) System Parameter Specification Reference Accuracy Up to ±0.025% of span Long-Term Stability Up to ±0.10% URL over 10 years Rangeability Up to 200:1 Response Time ≤ 100 ms Update Rate Configurable Operating Conditions Parameter Specification Process Temperature Up to 400°C (depending on seal configuration) Ambient Temperature -40°C to 85°C Maximum Working Pressure Up to 10,000 psi (689 bar) Hazardous Area Certifications ATEX, IECEx, FM, CSA Mechanical Specifications Wetted Materials: 316L SST, Alloy C-276, Monel (optional) Process Connections: Flanged Threaded Remote diaphragm seals Housing: Aluminum or Stainless Steel IP66/67 and NEMA 4X rated Key Advantages Over Capillary Systems ✔ No fill fluid ✔ No capillary-induced temperature errors ✔ Reduced installation complexity ✔ Faster response time ✔ Improved long-term stability ✔ Lower total cost of ownership Applications Distillation columns Reactors Storage tanks Boilers Oil & gas separators Chemical processing vessels Refining units Power generation plants Installation Features Electronic synchronization between sensors Remote mounting capability Reduced maintenance requirements Smart diagnostics Compliance & Certifications SIL 2/3 capable (depending on configuration) IEC 61508 certified NAMUR NE43 compliant Hazardous area approved Optional Features Advanced diagnostics Integrated LCD display Wireless connectivity Custom diaphragm seals Extended warranty options
