what is instrument mechanic and electrician?

Answer 1

'ag_iitkgp' almost has it right. When I started out many moons ago in the field of instrumentation, I was for ever being asked "What is that then"? First an 'instrument' is a device used to control or measure variables such as pressure temperature flow level etc etc. In those days ' instrument mechanic' looked after the 'clanky' bits like control valves and bits of pipe work, 'instrument techs' looked after the low voltage and electronic control side of the job.
As quite a bit of the initial training was electrical , employers thought they would 'lump in ' electrical to the job title hence instrument/electrical job designation.
Never a good move to my mind, the two trades are completely seperate.
However my day is done, who am I to say, but while I'm on the subject it took me five years to become a fully trained instrument tech, that is now covered in a couple of months and people are let loose as fully trained??? No chance.
As far as technical training goes in the UK we are cra*!
Sorry about that, I got a bit carried away there.
But I hope that answers your question?

Instrument mechanics specialize in the repair and maintenance of small and medium instruments. Electricians are repairers and installers of electrical appliances and fittings.
