. INTRODUCTION
DEFINITION:
Instrumentation is the branch of science that deals with measurement and control.
It is a specialization focused on the principle and operation of measuring instruments which are used in design and configuration of automated systems.
Instrument Composition
An instrument consists of;
system under measurement or measurand,
sensors/transducers,
signal conditioners,
signal processors and
effectuator / output (display, recording or storage).
INSTRUMENT OPERATION
Instruments mode of operation may be either
-manual,
-semi-automatic or
-automatic
This depends on the purpose and technology at the time of manufacture
Careless handling and misuse
Improper handling, storage and misuse
.
This could include
-damage during transportation or movement ,
-accumulation of dust,
-operation under harsh environments
-Spillage of corrosive substances
-leaving instrument powered /on for extended period of time.
Equipment Maintenance
- Maintenance is a process of keeping an instrument in a state fit for carrying out measurements by either
- preventing it from failing to function properly or
restoring it to the desired proper operating state after failure.
- Maintenance includes tests, measurements, adjustments, and parts replacement, performed specifically to prevent faults from occurring.
Support primary calibration laboratory.
- Machining and fabrication of spare for equipment e.g. adaptors for pressure testing.
- Engraving of dipsticks and scales in volume measurements.
- Design and development of testing rigs required in calibration e.g. a tensiometer Force laboratory,
- Development of calibration benches e.g. in Photometry lab
Machining Work and Other Metal Works
Some of the main machines found in the section are:
- Lathe machines
- Milling machines
- Welding machines
- Engraving machines
- Power saw
- Guillotine machines
- Grinding machines e.t.c.
