What “Infrared Leds?”
Wondering what the Accelerometer
The “Accelerometer”- It has the abilty to messure speed and detect movment.
Accelerometers are a very common way to measure vibration. However, acceleration vibration data is most useful for high frequencies while velocity data is suited to lower frequencies and in particular vibration found in most rotating machinery. Velocity vibration data is also a much better indicator of machinery health as it changes with a linear relationship to machine health. Velocity vibration data can be obtained from the MAV51 and MAV52 accelerometers both of which have built in integration circuits in them. To view how it work check out the video below.
