Overview
The B02A94 is a high-temperature uniaxial IEPE accelerometer built on a piezoelectric ceramic shear structure with an internal high-temperature, low-impedance circuit rated to +160 °C. With 10 mV/g sensitivity and a ±500 g range it is the highest-range model in the family, built for high-level vibration and moderate shock at elevated temperatures. Typical uses include engine, exhaust and turbocharger NVH, HALT/HASS and thermal-cycling chambers, and durability testing on hot assemblies.
High-quality piezoelectric material gives low temperature drift and a low thermal transient response, with wide bandwidth and low transverse sensitivity. The HEX 11 × 20.7 mm laser-welded stainless-steel housing provides exceptional sealing (IP68) and strength, with a top connector and an M5 mounting thread on the base, and 10-32 connector and thread versions available.
Why engineers choose the B02A94
Rated to +160 °C
A built-in high-temperature circuit and low-drift piezoelectric material keep the output stable from −50 °C right up to +160 °C, with a low thermal transient response, so readings stay clean through thermal cycling and on hot surfaces.
Built-in IEPE electronics
Integrated microminiature low-impedance circuit with 2–20 mA constant-current excitation and 8–14 V bias. Spectral noise of 24 µg/√Hz at 100 Hz drives long cables into any IEPE-compatible DAQ without extra conditioning.
Rugged stainless housing
Laser-welded HEX 11 × 20.7 mm stainless-steel housing sealed to IP68, weighing 9 g and rated to 2,200 g rms vibration and 5,500 g pk shock. Top connector with M5 or 10-32 options.
