8/31/2023 0 Comments How to determine sensitivityThe more information you share from the data sheet the better although I've now just noticed that the question is about three years old.Īlso, there may be some helpful insight at How sensitive are typical seismometers?ġ37 dB is a factor of $10^$ microns per second or about 1 nanometer per second, which is indeed a realistic number for some capacitive and optical displacement sensors. Sensitivity Percentage change in output / Percentage change in input Mathematically, the sensitivity analysis formulathat represents the dependent output can be written as follows: f(x) y X is the independent variable (input). However we don't yet know what the noise and bandwidth of your signal are yet so we can't evaluate that. In the example of a medical test used to identify a condition, the sensitivity (sometimes also named the detection rate in a clinical setting) of the test is the proportion of people who test positive for the disease among those who have the disease. Tl dr: if 137 dB is the dynamic range in power, then it's 68.5 dB in voltage and velocity which sounds more plausible, and makes the velocity sensitivity well below 1 micron per second. Hopefully you can add a little more information. This is a partial answer because I'm not an expert and because I don't know what the dynamic range of 137 dB means.
