Auburn Systems LLC invented triboelectric particulate monitoring and has been refining it ever since. We offer a variety of devices for process control, emissions monitoring and bag leak detection which are used in industries including aluminum, asphalt, carbon black, cement, chemical, food/dairy, foundry, furniture, glass, incineration, metals, mineral, paper, pharmaceutical , power, steel, tobacco & wood. Our most recent devices integrate both AC & DC signal processing for optimal performance. Auburn designs, engineers and manufactures advanced electronics . Our focus is developing and refining devices for particulate monitoring. We focus on bag leak detection for emission monitoring and solids flow monitoring for process control applications – particularly where accurate detection and monitoring saves our customers time and money. Regulatory compliance and process improvement are business challenges – not simple hardware tasks. And while we literally invented triboelectric monitoring, we don’t just rely on our large assortment of patents. We measure our application success by the return which we enable our customers to realize. While literally we monitor the triboelectric effect created by particles in a process, we actually help you do, what you do, better.

4. What Is Tribo
• The Triboelectric effect is a natural phenomenon and the cause of
static electricity
• When two materials collide – There is a transfer of charge
• When two materials closely pass by – There is an induced charge
• We measure it as current – pico amps

5. Triboelectric Monitoring
Basic Principles
Frictional Electrification – Impaction
When particulates collide with a probe, an electrical
charge will transfer between the particles and probe
Electrostatic Induction
Particulates in a gas stream also carry a certain amount
of net electrostatic charge and when passing by a probe,
an electrical charge can also be induced on the probe
