Type 4533-B is a general-purpose CCLD accelerometer with a low-noise preamplifier with built-in TEDS functionality. The accelerometer is part of the Type 4533-B and 4534-B accelerometers, based Brüel & Kjær’s patented ThetaShear® design. 

Both accelerometer types feature a wide frequency range, and have variants with sensitivities from 1 mV/ms–2 to 50 mV/ms–2.
