The DJB piezo-electric accelerometers

• DJB is patentor of the “konic” accelerometer, based on a piezo-electric element in the form of a truncated hollow cone. This method offers advantages such as a better reliability, and gives a higher sensitivity in a smaller unit when compared with a compressive type.

• Piezo-ceramic shear plate technology is also now used since offering even higher miniaturisation advantages, and sensitivity enhancement by virtue of parallel plate construction.

• Piezo-tronic accelerometers integrate charge/voltage converter and are energised from a constant current source, they generate a low impedance, noise immune voltage output.

• Industrial, high temperature, pressure tested and Intrinsically safe accelerometers are available.

• These transducers can be periodically checked by a DJB recalibration service
