Bruel & Kjaer 4384 Piezoelectric Charge Accelerometer
The Type 4384 Piezoelectric Charge Accelerometer from Bruel and Kjaer is for general purpose vibration testing and analysis. The DeltaShear design has three piezoelectric elements with three seismic masses that arrange in a triangular configuration, centered around a triangular center post. The Bruel and Kjaer Type 4384 piezoelectric accelerometer has a design that provides a high sensitivity-to-mass ratio and high-isolation from base strains and temperature transients.
