MODEL 1021B

The VIP Sensors Model 1021B is a miniature piezoelectric
accelerometer designed for shock and vibration
measurements on small structures and objects. Its mass of
only 1.4 grams 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 1021B 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 caseof the unit, but can be electrically
isolated from ground when used with an isolated mounting
bolt. The accelerometer features an integral cable with a 10-
32 plug for connecting to signal conditioning electronics.
VIP Sensors Signal Conditioner Models 5002 and 5005 are
recommended for use with this high impedance
accelerometer.
