Greetings everyone!
I am looking for a certain piezo sensor, actually an accelerometer, vibration sensor, shock sensor or however they call them these days. This accelerometer should pick up vibrations+shocks on a table at frequencies well within 5 Hz to 20.000Hz. Possibly even less top end freuqency down to 10kHz because I can hardly imagine any high frequ. going on in my application... The measurement range of acceleration (often given in g as the gravitational acc. constant) has to be in the area of +/- 150 g or even more... I don't want them to distort.
Are there other cheap piezos that have integrated electronics for impedance bridging, like the IEPE pieces, but only need a constant voltage supply? My observation is that the IEPE sensors are more on the expensive side and never availible under 50 $. Basically I want an easy solution to hook up the sensors to an analog-to-digital-converter without the need for much soldering.
A problem is also that the cheap sensors often do not have all the information in the datasheet... for example the amplitude range.
thank you so much
