Bentley vibration transmitter
Thread Content
Dear sea friends: I am a beginner disciple in the art of instrument playing, and I have a question I would like to ask everyone. I hope that experienced masters can give me some guidance; thank you in advance! How can the gap value be deduced after measuring the gap voltage? (As shown in the attached figure)
Thank you, big bro for sharing; I’ll learn from it*
Is it because my way of asking the question is wrong? Is the question too simple, so that no professionals are willing to reply?
I solved it myself; it seems there aren’t many people using this platform
There are many processes and equipment here, but indeed there are relatively few instrumentation and automation systems

Look at the sensitivity of the sensor that makes up this preamplifier; for example, Bentley’s is 7.87 V/mm. With this voltage value, it’s possible to calculate the distance, right? That’s right!
Hehe, just look at the picture. What reverse inference is needed?
Previously, 9.8V was the default zero point. If the difference is not significant, the zero point can be adjusted in the 3500 system
