Answer / zaiwar ali

when we increase the input of an instrument it gives some
output readings (follow a curve), now if we decrease the
same input and it gives different readings (follow another
curve) then this effect of instrument is called hysteresis.

Answer / sahnis

The delay between the action and reaction of a measuring
instrument.

Answer / luman

An instrument error that causes a difference in the readings
of an instrument when the indicated values are increasing,
compared with the readings at the same point when the values
are decreasing. Hysteresis error is caused by internal
friction in the instrument mechanism.

Answer / hamza zia

The non-coincidence between loading and unloading curves is called Hysteresis.

Answer / sahnis

The delay between the action and reaction of a measuring
instrument.

Answer / abdul wasid

The characteristics of an instrument that give the algebraic difference between the average results at corresponding points of measurement when approached from opposite directions.

Answer / maroon janakiraman.k

The difference between set value(action to taken) and pivot value(actual value in the reading) in the controller.

Answer / sajid

The Non-coincidence between these loading and unloading curve is know as hysteresis.

Answer / rinny

The characteristic loop we find when the instrument is calibrated first in one direction and then in the other..this is caused by friction or backlash

Answer / g.ramesh

the difference value b/w the set and reset value of the
controller is called as hysteresis

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
