Real-World Application: NCS-TT108 Multi-Channel Temperature Transmitter at Hunan Hongrun Chemical

Project Overview
Microcyber’s NCS-TT108 intelligent multi-input Fieldbus Temperature Transmitter was successfully deployed at Hunan Hongrun Chemical Technology Co., Ltd., a fine chemical production facility specializing in benzoic acid and related processes. The installation provides centralized, multi-point temperature monitoring in key production units such as reactors, distillation columns, and process pipelines, ensuring precise thermal control, process stability, and compliance with safety standards in a hazardous chemical environment.

Site Conditions and Challenges
The petrochemical plant operates under demanding conditions typical of fine chemical production:
– Corrosive and hazardous atmospheres requiring explosion-proof instrumentation
– Dense temperature measurement points across reactors, columns, and heat exchangers
– High cable volumes and complex wiring if using traditional single-channel transmitters
– Need for reliable, real-time data transmission to the DCS for continuous process optimization
– Strict requirements for accuracy, stability, and reduced maintenance in 24/7 operations
– Integration into an existing control system without major modifications

Why NCS-TT108 Was Selected
The NCS-TT108 was chosen based on its proven performance in chemical and petrochemical applications:
– Multi-Channel Efficiency: Integrates up to 8 temperature inputs (RTD or thermocouple) into one device, transmitting all data via a single fieldbus link – ideal for dense monitoring points
– Protocol Compatibility: Supports FOUNDATION Fieldbus (FF) – seamlessly integrated with the plant’s DCS for accurate, digital data exchange
– High Accuracy & Stability: Measurement accuracy better than Class 0.1; low temperature drift (±50 ppm/°C); precise cold-junction compensation (±1.0 °C) for reliable long-term performance
– Safety & Durability: Intrinsic safety explosion-proof certified (internationally recognized for FF); robust design suitable for Zone 1/2 hazardous areas; MTBF > 100,000 hours
– Cost & Installation Benefits: Reduces cabling by over 30%, replaces 8 single transmitters, lowers auxiliary equipment needs (barriers, distributors), and cuts lifecycle maintenance costs by ~40%

– Process Optimization: Accurate multi-point temperature data enables better reaction control, distillation efficiency, and energy savings in benzoic acid production
– Enhanced Safety & Reliability: Real-time hotspot detection and over-temperature protection reduce risks in hazardous chemical processes
– Significant Cost Reduction: Centralized architecture minimizes wiring complexity, installation time, and ongoing maintenance – delivering measurable ROI
– Proven Performance: The system has achieved accurate data transmission and substantial maintenance cost reductions, as validated in long-term operation at this site

This deployment at Hunan Hongrun Chemical demonstrates the NCS-TT108’s effectiveness in petrochemical and fine chemical applications, providing a cost-effective, reliable multi-point temperature solution aligned with digital fieldbus requirements.
