Instrumentation Finishing School

Synopsis

Many students finish their training without fully knowing what to expect in the workplace. This 10-day program aims to round off their initial training so that they can hit the ground running in the workplace.

Next course: 02 – 13 December 2019   Cost: R 15 000,00 (no VAT)

Content

The picture above shows the  areas covered. These include:

Digital signals: limit & proximity switches; other switch types; NPN vs PNP outputs; shaft encoders.

Temperature transducers: thermocouples vs RTDs; optical pyrometers; calibration

Transmitters: why; standard outputs; 2-wire vs 4-wire and why; dumb vs smart transmitters

Pressure measurement: aspects of pressure; Gauge-, Absolute- & Differential pressure; practical tips  regarding measurement; calibration of pressure transmitters.

Level measurement: point vs continuous measurement; common measuring techniques, pros and cons; calibration. Types of point level measurement in action.

Flow measurement: Liquid vs Gas; restrictions and ΔP; Pitot tubes; Vortex Shedding; Mag Flow;  Coriolis; Thermal Mass Flow;

Control valves: valve and actuator types; positioners; valve problems. Calibration.

Loop Control: Basics of PID; process dynamics and tuning; impact and handling of dead-time. Cascade /Feed-Forward /ratio control using a realistic computer simulation.

PLC programming & fault-finding: using a PLC that conforms to IEC 61131 specs, the essence of programming is taught, primarily for logical control, but incorporating timers, counters, number systems & variable types, comparators and simple arithmetic. A working model of a conveyor belt makes the experience as realistic as possible.

Variable Speed Drives: Basics of how VSDs work; the main components; advantages of VSDs; problems and pitfalls; system configuration. Specific VSDs can also be catered  for, given enough notice and enough demand.

This program is designed to be as hands-on as possible, with a very practical bias so that people attending get to grips with what is required in the field. Fault-finding is emphasized, as well as ways of preventing future problems.
