Answer / hiren

dp transmitter is used to measure DP but the pressure
applied across diaphargm is actual process pressure. so if
any one get fail then transmitter should not fail.

Answer / komal

Static Pressure is done on DP transmitter because of check
if the transmitter can withstand the static pressure acting
due to Line Pressure when in process. The Line pressure can
be 100 bar but the DP that is measured on transmiter can be
as small as 1000 MM H2O.

Answer / mhakave rajesh

it's span of measurement may be less eg 0- 5 bar,but
pressure acting on single side either of hp or lp (i.e.
process side pressure) may be high, so to check zero of tx
at such operating pressure it is........ so and so.

Answer / b.s.m.raju

This is DP transmeter high static preesure of 100 bar.
Small range will be used 10 mbar. but span range very low
Accuracy will be poor.

given a processor batch of 1000 resistors moving on the conveyor belting in a large factory. the resistors is value at 10k ohms each but when the resistors reach the quality control, some of the resistor has been rejected caused by failure in manufacturing.the high quality measurement is used to determine the failure. describe the instrumentation terminology in measurement of a system above with explaining the important in:- -reliability -sensitivity -repeatability -precision -range -resolution -linearity -hysteresis -error -accuracy (answer must related to the scenario above)
