Consider using the
"sweep down" function of your calibration system when calibrating
your general purpose accelerometers. This starts the frequency sweep
at the upper frequency limit, which coincidentally is the most
common frequency where an accelerometer can fail. If there is a
problem (such as loose transducer mount, missing silicone grease,
etc) the first measurement point will immediately fail, the
calibration operator can abort the measurement and then remount
the sensor. In older calibration systems, this saves 10-15 minutes
of sweep time per failed sensor and in newer systems it still can
save a minute or so.
Structure of Accelerometers...|
accelerometers are treated as a "black box" with little regard to
the internal construction.
The wide spread integration of built-in ICP® sensor power
into most modern day dynamic data acquisition systems often places
two wire, constant current signal conditioning in this "black box"
domain as well. As a result, many users have requested more
information on the structure and performance of dynamic sensors.
