The unit coded 3051S with serial number 5000615 is a high-performance scalable pressure transmitter from Emerson Rosemount’s premium 3051S SuperModule platform. Superior to conventional 3051C series, this transmitter is capable of differential, gauge and absolute pressure measurement. It is widely used in petrochemical, thermal power and oil & gas industries for high-precision flow measurement, tank level monitoring and critical process pressure control under demanding operating conditions.

Adopting advanced high-stability sensing module, it converts process pressure into standard electrical signal with digital communication function. The modular coplanar body can directly mate with 3-valve or 5-valve manifolds without extra transition adapters, simplifying impulse piping arrangement and minimizing fluid leakage points. Comprehensive built-in diagnostics continuously track plugged impulse lines, loop circuit faults and internal sensor degradation to reduce unexpected maintenance and unplanned plant shutdown. Every transmitter passes precision factory calibration and durability testing for quick on-site commissioning after installation.

Reference accuracy reaches ±0.025% of calibrated full span; total installed performance is better than ±0.10% full scale. Maximum turndown ratio is up to 200:1 to allow flexible onsite span adjustment without hardware replacement. Five-year long-term stability is controlled within ±0.0625% of set measuring span during continuous operation.

Standard output is 4–20mA analog signal overlapped with HART7 digital protocol, supporting remote parameter configuration via handheld communicator or DeltaV DCS. Optional communication types include FOUNDATION Fieldbus H1, PROFIBUS PA and WirelessHART per customer order. The standard loop-powered HART model works with supply voltage of 10.5VDC ~ 42.4VDC.

Standard wetted parts (isolation diaphragm and coplanar flange) use 316L stainless steel. Optional corrosion-resistant materials like Hastelloy C-276, Monel alloy and tantalum are available for corrosive medium and NACE sour service. Transmitter housing is cast aluminum with anti-corrosion epoxy coating, and premium sensor fill fluid is configured for stable performance under variable ambient temperature.

Operating and storage ambient temperature: -40℃ ~ +85℃; relative humidity 5%–95% non-condensing. Allowable process medium temperature depends on the selected fill fluid grade.

Optional backlit local LCD enables on-site real-time reading and zero-span trimming. Body-mounted push buttons support field calibration without additional tools. Advanced diagnostic features include impulse line blockage detection, circuit health monitoring and sensor drift early warning.

This transmitter complies with IEC61508 and holds SIL2/SIL3 functional safety certification, plus ATEX and FM explosion-proof approvals for hazardous area installation, covered by Emerson five-year limited factory warranty.

High precision flow measurement on critical process piping, accurate tank level detection for refined oil and chemical storage, precise pressure monitoring for power plant boiler circuits and chemical reactor equipment, as well as custody-transfer pressure measurement for oil and gas transmission pipelines.
