FREE to members.
Fee for non-members $30+HST.


In an age when information is the new currency, one of the cheapest and easiest bits of information you can extract from any industrial process is a pressure measurement. Yet many engineers leave this valuable resource on the table. Pressure measurements can provide valuable insight into other process variables including level, density, flow, temperature, velocity, altitude, and tomorrow’s weather.

At the completion of this one-hour OJT session, participants will be able to demonstrate the following:

· The underlying principles used to measure pressure including gauges and manometers.

· Why some gauges cost more than others.

· How much accuracy can you squeeze out of a gauge anyway?

· The pros and cons of mechanical vs solid state pressure instruments.

· How to calibrate pressure gauges, switches, and transmitters

· Pressure switches: Understanding turndown and dead band.

· How to apply gauges, switches and transmitters on process fluids that are chemically aggressive, abrasive, or viscous.

· The care and feeding of diaphragm seals and isolator rings
