Field notes on industrial operations intelligence — sensors, edge telemetry, and machine learning for processing plants.
Energy per Tonne: Benchmarking Specific Energy Use
Why specific energy consumption is the metric that actually exposes plant efficiency, and how to benchmark it without lying to yourself.
Cold Chain Monitoring: 5 Myths That Cost Product
Five things vendors and managers get wrong about cold chain temperature monitoring, and what actually catches an excursion in time.
Industrial AI in Food & Beverage: Yield, Uptime, Quality
Where machine vision, soft sensors, and predictive maintenance actually have to run on a regulated production line.
Digital Twins in Process Plants: Where They Pay Off
Telling a synchronized twin from a dashboard, and a four-line test for whether a process plant should build one.
Computer-Vision Scrap Sorting: Cleaner Charge, Less Copper
Cameras grade scrap by sight, but it takes spectroscopy to read the copper that wrecks a heat, and a control loop to act before the grab closes.
NIS2 for Industrial Operators: What EU Plants Must Do
How the EU's NIS2 directive turns into concrete OT controls on a processing plant floor, built in the order that actually works.
Choosing a CEMS: Extractive, In-Situ, or PEMS
Continuous emissions monitoring isn't one technology. Pick extractive, in-situ, or predictive on accuracy, latency, availability, and who maintains it.
Soft Sensors: Keeping an Inferred Measurement Honest
Choosing, validating, and maintaining inferential sensors that survive their first feedstock change.
Securing Industrial Control Systems with IEC 62443
How to cut a processing plant into zones and conduits, set a security level for each, and build a boundary that actually holds.
Combustion Efficiency on a Waste-to-Energy Boiler
Why squeezing the burn on a plant that runs on garbage is a control problem you fight every shift, not a setting you dial in once.
Computer-Vision Quality Inspection: Five Myths
A vision cell sees what a tired inspector misses, but only if the engineering and the claims around it are honest.
