    accelerometers or velocimeters - AirMech

    Which does a HUMS system use? Or does it use a combination of both? Accelerometer seems to be used as a general term for a vibration sensor but I know velocimeters are better for low to medium frequencies and used for RTB. What about the higher frequencies involved with engine vibrations? Just trying to get a more accurate understanding of the systems and the terminology. The iPhone has an accelerometer like most smart phones. Here is an experiment to determine the location of this sensor. Accelerometer The ultra-small BMA280 is an advanced, triaxial, low-g acceleration sensor with digital interfaces, aiming for low-power consumer electronics applications. It senses tilt, motion, shock and vibration e.g. in cellular phones, man-machine interfaces, VR features and game controllers.

    APPLICATIONS OF VIBRATION TRANSDUCERS

    accelerometer the piezoelectric crystal produces an electrical charge which is connected directly to the measurement inst ruments. This type of accelerometer is also used in high temper ature applications (>120C) where low impedance models cannot be used. The second type of accelero meter is a low impedance output accelerometer. A low represents its own domain. Modeling shows that geophone and digital accelerometer output is similar in appearance. In laboratory tests, both sensors matched their modeled responses over a wide range of amplitudes. Since the response is accurate in practice, it is used to calculate ground acceleration from geophone output. Comparison of Apple iPhone product line comparison Products > High-Tech > Phones.

Physical principles. An accelerometer measures proper acceleration, which is the acceleration it experiences relative to freefall and is the acceleration felt by people and objects. Put another way, at any point in spacetime the equivalence principle guarantees the existence of a local inertial frame, and an accelerometer measures the acceleration relative to that frame.

    Difference betwen a velometer and an accelerometer | AMP ...

    "In any event why would we use a velometer over an accelerometer? does a velometer have special applications?" The OP asked the above. You use a piezo-velocity transducer for several reasons, limitation of noise, no-lag velocity signal, limitations of diagnostic equipment, and maybe some other reasons. A pedometer senses your body motion and counts your footsteps. By knowing the length of your usual stride you can convert this count into distance. An accelerometer is a more advanced pedometer. It also shows your speed and distance. In an accelerometer, a strain gauge allows the device to know how hard or soft each […] (b) Make Sure the Accelerometer is Firmly Attached. For the accelerometer to detect true vibration behavior, it needs to undergo exactly the same vibratory movement as the vibrating component. An accelerometer must therefore be attached firmly to the vibrating component so that it does not rock or move independently of the component. A loosely ...

    What does the iPhone accelerometer do? | HowStuffWorks

    Before we can say what the accelerometer of the iPhone does, we need to understand the basics of what an accelerometer does in general.

An accelerometer can therefore measure the speed of movement of an object it is attached to ... The iPhone 5S level is powered by the phone's accelerometer, and according to developer RealityCap, the reason we've been seeing problems is that Apple switched hardware vendors for the part.

    Difference between accelerometer and vibration sensor ...

    Newer ones tend to use a MEMS accelerometer to detect vibrations. Accelerometer-based vibration sensors often capture acceleration data at a high rate. The built-in DSP uses a band pass filter to eliminate the very high frequency noise and to eliminate the low frequency accelerations that are of little interest when it comes to detecting vibrations. That's how an iPhone or an iPod Touch automatically figures out when to switch the screen layout from portrait to landscape. Many games and "apps" designed for gadgets such as iPhones work by sensing how hard or how fast you move or shake the case using tiny accelerometer chips inside. Accelerometer, Gyro and IMU Buying Guide Accelerometers and gyros are becoming increasingly popular in consumer electronics, so maybe it's time you added them to your project! Scrolling through SparkFun's sensors category reveals a huge list of these sensors that might be perfect for your next project, if only you knew what they did, and which one best fit your project.
