How to design Intrinsically Safe Instrumentation is the topic of the third seminar of the 'Robust Electronics Essentials' series. Electrical circuits in many industrial environments must operate in the presence of volatile gases. In these environments, intrinsically safe instrumentation design principles are employed to prevent the electronic circuits from releasing sufficient energy to ignite any gases which may be present. Intrinsically safe circuits must have three major components: the field (intrinsically safe) device, the energy limiting device (also referred to as the barrier), and the field wiring. The Intrinsically Safe Instrumentation Essentials seminar will present material on all three of these components. The engineering professional will understand the problems associated with intrinsically safe instrumentation after attending this seminar, and be able to generate appropriate instrumentation implementations. It is assumed that the attendee has basic engineering knowledge but is not necessarily an expert in instrumentation systems.
The seminar focuses on intrinsically safe instrumentation techniques that guarantee upper limits for energy release in hazardous environments. An electronic presentation will be provided with a hard copy of all slides and additional notes being supplied to attendees.
The following topics are addressed:
- Hazardous area sensing.
- Principle of intrinsic safety.
- Intrinsic safety barriers.
- The 80/20 design rule.
- Intrinsically safe analog and digital inputs and outputs.
- Standards and certification.
- Design examples and testing.
The intended audience is electrical and computer engineers working with electronics, embedded systems, computer and instrumentation systems and measurement systems. Guidance is provided to the engineering professional who needs to solve intrinsically safe instrumentation problems. It is assumed that the attendee has basic engineering knowledge but no previous instrumentation knowledge is required.
