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

A pressure transmitter with a range of 0-100 bar.The accuracy of the instrument is 1% of upper range value? The pressure indicating transmitter is showing the system pressure is 50 bar. b. When you include the error, what is the minimum possible pressure in our fuel gas system? i. 49.5 bar ii. 49 bar iii. 1 bar iv. 0.5 bar We want to change the filter cartridge. We must depressure the fuel gas system. c. After we depressure the system in preparation for maintenance, the transmitter displays a pressure of +0.1 bar. At this time, what is the possible range of pressures in our fuel system? i. +0.099 to +0.101 bar ii. 0 to +0.2 bar iii. -0.1 to +0.3 bar iv. -0.9 to +1.1 bar
