1021A

Quality Innovations Customer Satisfaction PIEZOELECTRIC ACCELEROMETER • Miniature Design • Ideal for High g Shock Measurements • Frequency Response to 12 kHz • Thru-Hole Bolt or Adhesive Mounting • 360° Cable Orientation • Replaceable Cable 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.
