Current sensing amps convert voltage output

[danny davis]

Are current sensing amps have a linear output?

Because at my job , there is a variable pot for the input, but there is a Time delay also before there is an output voltage plus the output voltage is not LINEAR compared to the linear taper of the variable pot on the input

It seems that the circuit is a current to voltage convert

But when converting an input current to voltage , the input and output are not matched and not linear, is this common and normal? plus there is a TIME delay on the input it seems , because u can more the variable pot and it takes time to get a voltage output

Why do circuits that are current to voltage converts have a time delay on the input?

A simple resistor is a current to voltage converter. Current in a resistor produces a voltage across it according to Ohm's Law. An opamp is used to amplify it. It should be linear unless there is a diode or transistor logarithmic converter.
We do not know why your circuit has a time delay. Maybe it allows bursts of high current but triggers with steady current.
Please post its schematic.
