Accelerometers - KISTLER - #9

Overload protection is incorporated in all designs with the surrounding electrodes lim­iting displacement of the seismic mass. Also, damping is achieved in some designs result­ing from the compressed cavity gas reduc­ing transient stresses. The relatively rugged construction compares well against competi­tive strain gage type accelerometers. Power requirements are simple where often a single nine-volt battery connection is all that is re­quired in addition to the output lead. The ease of installation combined with a robust, reliable sensor has guided these accelero-meters into many applications formally out­fitted with piezoresistive or expensive Servo type accelerometers.

Ride quality studies in many areas of trans­portation such as automobiles, trains, air­craft and marine vehicles have utilized the variable capacitance products where the fre­quencies of interest and ease of use make their selection obvious. The operation and refinement of wafer fabrication equipment has been extensively investigated using K-Beam accelerometers that are well adapt­ed to measure the low level, low frequency events common to the processes. Dynamic studies on large structures require great accuracy at very low frequencies and again are an ideal fit to the variable capacitance product range.
