Description
The VIP Sensors Model 1021A is a miniature piezoelectric
accelerometer designed for shock and vibration measurements
on small structures and objects. Its light weight minimizes or
eliminates any mass loading effects on the object being tested.
The accelerometer is a high-impedance, self-generating device
that requires no external power source for operation.
The Model 1021A incorporates a thru-hole mounting design
that allows for cable orientation in any direction. The unit is
sealed against external contamination. Signal ground is
connected to the outer case of the unit. The accelerometer
features a M3 connector that is used with low-noise coaxial
cable for connecting to signal conditioning electronics.
VIP Sensors Signal Conditioner Models 5002 and 5005 are
recommended for use with this high impedance accelerometer.
