Answer / karthik

A type of differential amplifier with high input impedance
and low output impedance.Mostly used in all Transducers
because of its common mode rejection ratio property so that
noise can be eliminated from signal produced by primary
sensing element.

Answer / jobby c johnson

instrumentation amplifiers commonly known as INAMPS are
differantial amplifiers having high input impedane, low
output impedance. the gain of inamps are also very high.
basically the the circuit consists of 3 opamps, two of them
are voltage followers and one differantial amplifier

Answer / raja

an instrumentation amplifier may be defined as
conversion of any physical quantity into an
electrical quantity at the output.
hence it is coupled at the output of the
transducer and used as an data acquisition system

what is the difference between Feedback controller and Feed forward controller. and when it is to be used.

How can we say that accuracy of measurement increases by using 3 or 4 wire RTD? because for example: If resistance of RTD element is say r ohms and Resistance of the cable from transmitter to RTD is R ohms And if 4 wire RTD is used, ____._____________________ R ohms | |_____._____________________ R ohms / \ / r ohms \ \ | |______.__________________ R Ohms | |_______._________________ R ohms Then the actual resistance measured will be: Total = r + R/2 + R/2 = r +R Ohms Note: r+R instead of r ohms. hence error
