Engineered for reliability in explosive atmospheres, the 5081-P combines advanced electrochemical sensing technology, rugged explosion-proof housing, and digital communication capabilities to meet the demands of critical processes in oil and gas, chemical processing, power generation, and water/wastewater treatment. Its ability to provide real-time, multi-parameter data ensures optimal process control, regulatory compliance, and safety in challenging applications.Core Technology and Operating PrincipleThe Rosemount 5081-P integrates electrochemical sensor technology to measure pH, ORP, and contacting conductivity simultaneously. For pH measurement, the transmitter uses a glass electrode that generates a voltage proportional to hydrogen ion concentration, referenced against a stable internal electrode. ORP is determined by a noble metal sensor (e.g., platinum or gold) that detects electron transfer in redox reactions, indicating oxidation or reduction potential. Conductivity is measured via a contacting electrode pair, which calculates the solution's ability to conduct electricity based on ion concentration.A key innovation is the digital signal processing (DSP) engine, which filters electrical noise and compensates for temperature variations, ensuring stable readings even in harsh environments. The transmitter supports sensor diagnostics, including electrode coating detection, drift analysis, and calibration alerts, to maintain measurement integrity. Its modular design allows seamless integration with Emerson's Rosemount Analytical sensors, enabling plug-and-play configuration without manual input.Technical Performance and FeaturesThe 5081-P delivers exceptional accuracy and versatility:pH Measurement: ±0.01 pH resolution with a range of 0–14 pH, suitable for corrosive, high-purity, or wastewater applications.ORP Measurement: ±1 mV resolution from -2000 to +2000 mV, ideal for monitoring redox reactions in chemical dosing or disinfection processes.Advanced Diagnostic and Asset Management FeaturesThe 5081-P incorporates predictive diagnostics to enhance operational reliability and reduce unplanned downtime:Sensor Health Monitoring: Detects electrode fouling, coating buildup, or sensor degradation, providing early warnings of potential failures.Calibration Validation: Automatically verifies sensor accuracy against reference buffers, minimizing manual calibration frequency.Signal Integrity Alerts: Identifies electrical noise, grounding faults, or wiring issues affecting measurement stability.Self-Validation: Periodic checks ensure compliance with regulatory standards (e.g., FDA 21 CFR Part 11) without process interruption.These diagnostics are accessible via HART, Fieldbus, or Emerson's AMS Device Manager, enabling proactive maintenance planning and compliance with functional safety standards like IEC 61508 (SIL 2/3).Ease of Use and IntegrationInstallation and configuration are streamlined through intuitive interfaces:Local Display: A backlit LCD with push-button controls allows on-site setup and troubleshooting without removing the transmitter from the process.Remote Configuration: HART or digital protocols enable adjustments using handheld communicators, mobile apps (e.g., Emerson Mobile Remote View), or control system interfaces.Digital Twin Compatibility: Integrates with Emerson's PlantWeb? ecosystem for real-time analytics, predictive maintenance, and performance optimization.The 5081-P's universal design supports multiple sensor types and mounting options (e.g., retractable, immersion, or flow-through), simplifying retrofitting into existing pipelines or vessels.Applications Across IndustriesThe 5081-P's versatility makes it ideal for critical applications:Oil and Gas: Monitoring produced water pH/ORP and conductivity in offshore platforms and refineries to prevent corrosion and ensure pipeline integrity.Chemical Processing: Controlling pH/ORP in acid/base reactions, neutralization processes, and solvent recovery systems.Power Generation: Managing boiler feedwater and condensate purity to prevent scaling and turbine damage.Water and Wastewater: Tracking effluent pH/ORP and conductivity to meet discharge regulations and optimize treatment efficiency.Company ProfileCompany ProfileKeRul (WeiFang) Automation Equipment Co., Ltd. is speciallzed in industrialautomation instrument development, production and sales, technical servicesand supporting equipment supply of specialized companies, The mainproducts are fow meters, level meters, temperature meters, pressuremeters, electrical meters, thermal meters, programmable controller(PLC), Dcs distributed control system, eight series of more than 1,000specifcations. its products and technologies are widely used in electrlcpower, metallurgy, petrochemical, environ. mental protection, plastics,food,l printing, tobacco, textile, dyeing and other fields.Our ServiceOEM / ODM servicesTo meet the user diversified requirement, Holykell have established a set of customer service and technical support system with OEM / ODM order as the center, and responded and Handle the customer's requirements in a timely manner to ensure accurate delivery time and product quality.Order servicesFastest reply:Professional sales engineers 7/24 online servicesPayment terms:T/T ,Western union, Paypal, Credit Card, L/C othersFast delivery: within 24 hours release the cargo (normal spec.), Customized 7-12 days after payment .
