B03B94

The B03B94 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 20 mV/g sensitivity and a ±250 g range it is a versatile mid-range member of the family, balancing range, bandwidth and noise for general vibration work in hot environments. Typical uses include environmental testing, ESS, vibration control on heated fixtures and general monitoring near engines and process equipment.

High-quality piezoelectric material gives low temperature drift and a low thermal transient response, with wide bandwidth and low transverse sensitivity. The HEX 13.1 × 18.8 mm laser-welded stainless-steel housing provides exceptional sealing (IP68) and strength, with a side connector and an M5 mounting thread on the base, and 10-32 connector and thread versions available.

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 12 µg/√Hz at 100 Hz drives long cables into any IEPE-compatible DAQ without extra conditioning.

Rugged stainless housing

Laser-welded HEX 13.1 × 18.8 mm stainless-steel housing sealed to IP68, weighing 14 g and rated to 3,000 g rms vibration and 5,000 g pk shock. Side connector with M5 or 10-32 options.
