I wanted to write about static and dynamic characteristics of the Honeywell pressure 19mm transducer. I found my sensors datasheet but could not find the following characteristics mentioned in the datasheet directly.Could you help me know if any of the below are mentioned in the datasheet.

Characteristics : Accuracy, Precision, Sensitivity, Linearity, Resolution, Reproducibility, Repeatability, Threshold, Tolerance, Range, Stability, Drift, Hysteresis, Speed of Response, Measuring Lag, Fidelity, Dynamic Error, Noise.

I found some like Time Response, Range, Repeatibility because they were directly written.

  • \$\begingroup\$ The desired parameters exist in the datasheet in the performance section. It just doesn't give directly. \$\endgroup\$

  • \$\begingroup\$ You can't write anything to these analogue bridge pressure sensors. You stick a supply on it and use an ADC (or similar) to read the output voltage. \$\endgroup\$

  • \$\begingroup\$ Why are you interested in these particular characteristics? What are the actual requirements of your application? \$\endgroup\$

  • \$\begingroup\$ This strikes me as a homework assignment. What have you been able to figure out so far? Other than things that are directly written there. \$\endgroup\$

  • \$\begingroup\$ @NickAlexeev You guessed it right. I didn't figure out much but enough to finish homework. \$\endgroup\$

Some seem redundant, but this should cover most of it.

Accuracy: How much can you trust that reading X is exactly X

Precision: How small of a step of the output is generally meaningful, like saying you have 2.0000 hands does not really add anything,

Sensitivity: How small of a change on the input will cause the output to change

Linearity: If you take a reading at a low value, and a high value, how likely is a value in the middle of them to be exactly the same, as an alternate how straight a line would it draw if you plotted input vs output

Resolution: the smallest possible change in the output, generally smaller than precision.

Repeatability: You start at value X on the input, you change the input to some other far away value, you then go back to value X on the input, how close will the output be to the original you records at input X.

Range: How large can you measure between the smallest output value and the largest

Stability: At different temperatures and supply voltages how much will the output vary

Drift: Over time, be it days, months or years, does the output value drift higher or lower than original, and by how much.

Hysteresis: what is the difference in output between increasing the input to a value, and decreasing the input to a value.

Speed of Response: How quickly the output will change to a change in the input

Fidelity: Related to precision,

Noise: Provided the input does not change, how much might the output move up or down from that value on average over a short time period, this may be due to supply noise coupling in or thermal noise generated in the device.

  • \$\begingroup\$ Thanks. It is clear now about the terms. But I could not find most of the above terms in the datasheet. Is there a different technical alias used or something? For example, I couldn't find sensitivity mentioned. \$\endgroup\$
