Konic Shear™ . . . why not all accelerometers are the same!
What is cross-axis signal and why do I need to know/worry about it?
Measurement direction and cross axis:
Cross Axis is the effect of a vibration input to an accelerometer signal from a direction perpendicular to the measurement axis, i.e.
How critical is accelerometer cross axis signal contribution?
The next question is how many engineers and accelerometer users know what it is?
. . . we will let you answer that yourself!
For those that want to consider it, here are a few questions to ask:
What does this mean for the user?
How do accelerometer manufacturers control cross axis signal contribution?
What happens to pre-polarisation?
What can I do to minimise errors?
Always have the cross axis checked during the annual calibration, otherwise errors can accumulate to exceed 35% of your signal!
How do DJB control Cross Axis signal contribution?
The Konic Shear™ design which is unique to DJB, has natural cross axis compensation (i.e. signal cancellation) due to the nature of its design (conical sensing material), coupled with pre-polarisation, it gives long term cross axis stability, unrivalled by any other accelerometer on the market today.
