Columbia Research Laboratories has developed a group of piezoelectric general purpose accelerometers that are ideal for a wide range of shock and vibration applications. The 3000 Series standard size units include many with all welded construction that are hermetically sealed for use in dirty and humid environments. The unique design of the piezoelectric seismic system inherently provides complete mechanical isolation of the sensing element. This design makes the sensors insensitive to mounting torque, body strains, cable vibration, cable whip, pressure variations, and most heat transients. The signal is self generating, requiring no external power source. These units offer wide frequency ranges and are available in high temperature versions. The 5000 Series are smaller and lighter in weight than standard units. Characteristics are almost identical to standard units except that with the smaller, lighter units, higher natural frequencies and shock levels can be obtained due to their reduced mass. Sensitivities, however, are somewhat lower.
For best performance, Columbia model 4601 Charge Amplifier, Series 5684 Airborne Amplifiers, or 5421 Power Supply combined with inline charge converter model 5810 are recommended for use with these high impedance accelerometers. Additional mounting adapters and cable assemblies are also available.
