PCB Piezotronics supports design, research, and development efforts with precision accelerometers* for the measurement of vibration, shock, acceleration, and motion. In addition to our miniature precision units, our rugged accelerometers are used for industrial machinery health monitoring for the evaluation of equipment and structural performance. Such applications usually require proof of calibration of the entire measurement system, from sensors to final output.

PCB provides ICP® (IEPE), PE, MEMS, and capacitance sensing technologies to satisfy these various measurement requirements.

*Accelerometers are sometimes referred to as "accels," "vibe sensors," or "vibe probes."

Key features of PCB accelerometers

PCB’s accelerometers are trusted by experts for their high-quality components, and feature:

  • High stiffness, ruggedness and durability
  • Wide dynamic ranges
  • Fast rise times
  • Versatile frequency ranges
  • Consistent, repeatable results

Our calibration centers are accredited to ISO 17025, and each sensor shipped includes a calibration certificate traceable to NIST. A lifetime warranty and same-day shipping are standard with our platinum stock sensors program.

Accelerometer technology

The most commonly used technology is ICP® (IEPE) accelerometers, which require ICP® power. (ICP® sensors can be referred to as IEPE or voltage mode output sensors, while PE sensors can be referred to as charge mode output sensors.) Most modern data acquisition, digital control, and portable data systems provide ICP® sensor power. Each directional axis measured requires one channel of the data system or signal conditioner.

Single-axis and three-axis (triaxial) accelerometer configurations include specifications on sensitivity, temperature, frequency response, amplitude response, form factor, and lead wire grounding.
