Overview
The B05BG2 is a uniaxial IEPE accelerometer built on a piezoelectric ceramic shear sensing element with a wide-bandwidth frequency response. With 50 mV/g sensitivity and a ±100 g range it is a high-sensitivity model in the BXXBG2 family for low-level vibration where signal-to-noise matters more than g range. Typical uses include structural and modal testing, vehicle body and cabin NVH, rotating machinery monitoring and low-amplitude R&D measurements.
An integrated base-isolated design fully isolates the signal ground from the mounting surface, breaking ground loops on conductive structures. The built-in low-impedance IEPE circuit provides low output noise and an excellent sensitivity temperature response, and the compact HEX 12.7 mm titanium-alloy housing is laser welded to IP68. Available with M5 or 10-32 connector and mounting thread.
Why engineers choose the B05BG2
Base-isolated design
An integrated isolation base gives full signal-ground-to-housing isolation (≥ 10⁸ Ω), so the sensor can be stud mounted on conductive structures without ground loops or noise pickup.
Built-in IEPE electronics
Low-impedance IEPE circuit with 2–20 mA constant-current excitation. Spectral noise of 8 µg/√Hz at 100 Hz, 0.0002 g rms broadband resolution and an excellent sensitivity temperature response.
Compact titanium housing
Laser-welded HEX 12.7 × 16 mm titanium housing sealed to IP68, weighing just 7.5 g and rated to 800 g rms vibration and 2,000 g pk shock. Side connector with M5 or 10-32 options.
Typical applications
Modal and structural analysis
General-purpose vibration monitoring
Measurements on electrically live or conductive structures
Automotive and machinery NVH
Multi-channel tests where ground loops must be avoided
General uniaxial vibration measurement
