What is the difference between Analytical instruments and
other instruments?
Answer Posted / sam
Yes, I see what you mean it can be a bit confusing.
Instrumentation is a very wide field so the easiest to
explain would be to classify all the various areas in
different categories, but they are all part of the
instrumentation field.
Process measuring instrumentation, like pressure,
temperature, flow, density, level, viscosity, conductivity,
PH, redox, distance, angle ext.
Process control instrumentation, like control valve, on/off
valve, solenoids valves, valve positions, feedback positioners.
Monitoring and control instrumentation, like the DCS, SCADA,
PLC's and relay control systems.
Pneumatic instrumentation, like pneumatic valve positioners,
electromagnetic positioners, DP transmitters, level trolls,
switches and pneumatic relays and pistons.
Hydraulic instrumentation, like hydraulic control systems,
pneumatic/hydraulic solenoid valves, hydraulic control
valves, feedback positioners and pistons.
Fire and gas instrumentation, like flame, gas, smoke, heat
detectors and the addressable monitoring and control
systems. CO2, foam, 440VAC foam control valves and deluge
systems and their pneumatic and solenoid control systems
will also fall in this category.
Analytical instrumentation, like oil in water, gas
chromatographic, oxygen content, chlorine content,
florescence, dew point analyzers.
Good luck
