How it works

Schematic · not to scale

Stored grain can look quiet while biological activity is changing inside the bin.

A sensor samples air above stored grain; its reading is compared with other measurements before action.

  1. Stored grain and associated organisms can remain biologically active. Temperature, moisture and ventilation influence conditions in storage.

  2. Respiration releases energy and can produce CO2. OPI uses CO2 measurements as an indicator alongside temperature and moisture.

  3. A measurement describes the air at a sensor and a moment in time. Airflow and placement affect what that reading can reveal.

  4. A changing pattern can prompt inspection or a management decision. Several measurements together are more informative than treating one CO2 value as proof of a particular problem.

Respiration is the biological connection; this is not a bin-management guide. Do not claim that all CO2 comes from mould or that a stable temperature proves grain is unaffected. No grain-bin entry activity.

Role

Instrumentation and controls

Keep a process measurable and responsive. Controls work connects sensors, decisions and actuators so the system can respond when conditions change.

Company describes engineering, production and support functions. Sensor, software and troubleshooting duties below are interpreted work explanations; current individual Calgary job assignments are not established.General explanation, written by usSource: opisystems.com — contact(opens in a new tab); opisystems.com — from an ounce of prevention to every grain to market(opens in a new tab); opisystems.com — for commercial(opens in a new tab); opisystems.com — co2 monitoring(opens in a new tab); opisystems.bamboohr.com — careers(opens in a new tab)

What might you actually do?

  • Investigate

    Check whether sensors are reading reliably.

  • Test and compare

    Compare measurements with the intended operating range.

  • Explain and improve

    Test how the system responds to a change or fault.

Ask the class

Use it in class

Ask the class

What else would you measure before deciding that a CO2 increase means spoilage?

Compare two fictional bins over three checks. Bin A: relative CO2 index 1.0, 1.1, 1.1; Bin B: 1.0, 1.5, 2.1. Both temperature records appear stable. List two explanations, choose a follow-up measurement, and explain why these dimensionless indices cannot be used as operating thresholds.

Mindset it shows

Respiration is the biological connection; this is not a bin-management guide. Do not claim that all CO2 comes from mould or that a stable temperature proves grain is unaffected. No grain-bin entry activity.
