SMART INSTRUMENTS IS THE INSTRUMENTS WHICH ARE USED FOR
CONTROLLING THE PROCESS VARIABLES, BUT I DONT KNOW THE
EXACT EXPANSION OF SMART.

Answer / abdu salam tc

The term smart is not an abbreviation of something, It is
only a term for identifying the instrumentation instruments
having a programmable internal memory and setup for
configuration and calibration. These type instruments does
not need to apply any process inputs for calibration as
conventional instruments. The term HART (Highway
Addressable Remote Transducer) is the protocol used in
almost all the smart instruments.

"Smart" is a marketing term, not a technical definition.
Hence, smart means whatever the speaker attempts to define
it as, but you as the listener, are not obliged to accept
the speaker's definition.

Over the past 20 odd years, I have had people tell me smart
is:

1) the ability to have the transmitter's output ranged
without applying an input

2) the ability to zero/range the transmitter output by
applying a process input and pressing a button

3) the ability to configure an elevation offset on a GP/DP
transmitter without applying a pressure.

4) the presence of a digital indicating readout on a
transmitter, as opposed to an analog indicator.

5) the compensation for temperature drift on pressure
transmitters by measuring the temperature and making
compensation for it.

6) the ability to change engineering units for the digital
indicator.

7) the presence of any digital interface, whether it be
HART, foundation fieldbus, Profibus, or even Modbus.

8) the ability to get more than one variable from a
transmitter.

9) the presence of 'meaningful diagnostics'. The repeated
assertion of the value of 'meaningful diagnostics'. The
failure to show a 'meaningful diagnostic' or be able to
explain what any specific 'meaningful diagnostic' might be
meaningful.

10) The ability to configure a transmitter remotely from
the control room, over the wiring to the transmitter, with
a handheld gizmo.

11) That newer transmitters are, in fact, smarter than
older transmitters because the handheld gizmo has 2 LCD
lines in the display, instead of one.

12) The absence of screw adjustment pots

13) Not drawing to an inside straight.

I believe only the last definition. You are entitled to
believe whatever you heart desires. Even a former US
president didn't know the definition of 'is', so who's to
define "smart"?
