Miniature shock sensor
PCB Piezotronics

Series 3501 and 3503 MEMS high amplitude shock accelerometers from PCB Piezotronics (PCB®) represent state-of-the-art industry technology for miniature, high-amplitude, DC response acceleration sensors, capable of measuring long duration transient motion, as well as responding to and surviving extremely fast rise times typical of a high-G shock event. Both a packaged and a OEM configuration are offered to fulfill a variety of installation requirements.

The air-damped acceleration sensing element, which is micro-machined from silicon, is manufactured with the latest advances in etching techniques and equipment. This tiny element measures just 2.5 x 1.7 x 0.9 mm (l x w x h) and incorporates a seismic mass, protective overrange stops, and a full-active, piezoresistive Wheatstone bridge.

Series 3501 and 3503 are intended to fulfill the most demanding aerospace, industrial and commercial application requirements. Their design concepts were born from more than 20 years of PCB® expertise in very high G shock (> 20,000 G) measurement applications and sensor development. Our design team has the most experience in the world for these applications. Our process engineers utilized the latest and most sophisticated techniques and equipment to achieve the desired performance levels that previously have not been attainable.
