_______ indicates the maximum deviation of the actual measured curve of a sensor from the ideal curve.

Explanation:

Dead band: 

• The Deadband of a transducer or sensor may be defined as the range of input values for which there is no input.
• For instance, if a pressure sensor can sense beyond a threshold value of say 4 Pa and above but not from 0 - 4 Pa then the dead band of that sensor is 0 - 4 Pa.

Span: 

• It is defined as the difference between the maximum and minimum input of a measuring device.​

Non-linearity:

• It is defined as the maximum deviation of the actual measured curve of a sensor from the ideal curve.

​

Non-linearity depends upon;

• Temperature
• Vibration
• Noise
• Humidity

Hysteresis: 

• The maximum difference in measurement within the specified range is known as Hysterisis.
