PCB Piezotronics Expands Seismic Accelerometer Portfolio for Ultra-Low Vibration Measurement

Introducing PCB Model 354A12 Seismic Triaxial ICP® Accelerometer


February 2, 2026 - Depew, NY - PCB Piezotronics (PCB®) is pleased to announce the expansion of its seismic ICP® accelerometer portfolio for ultra-low frequency vibration measurement. The expanded offering includes the new triaxial Model 354A12, alongside updated single-axis seismic accelerometers Models 393B03 and 393C12, providing engineers with flexible options for precision vibration monitoring in sensitive environments.

Model 354A12 is PCB's first triaxial seismic ICP® accelerometer developed for long-term installation in structures and machine bases. With a sensitivity of 10 V/g and a low-frequency response down to 0.17 Hz, the 354A12 delivers clean, precise vibration data across all three axes. Its case-isolated, hermetically sealed stainless-steel housing and dual through-bolt mounting make it well suited for permanent installations.

The expanded portfolio also includes Models 393B03 and 393C12, single-axis seismic accelerometers featuring the same proven performance and package as previous designs, with refined mechanical construction to support dependable long-term availability. These models offer high sensitivity and extended low-frequency response for applications requiring micro-g-level resolution.

Applications include semiconductor processing equipment, optical systems, structural health monitoring of bridges and historic structures, smart buildings, and infrastructure exposed to low-level environmental vibration from traffic, machinery, or seismic activity.

Key Features:

  • Ultra-low frequency measurement capability for seismic applications
  • High sensitivity output with micro-g resolution
  • Single-axis and triaxial configurations available
  • Hermetically sealed stainless-steel or titanium housings
  • Designed for long-term monitoring in demanding environments
