New Series of MEMS Shock Accelerometers

Depew, NY, USA – June 22, 2009 – PCB Piezotronics, Inc., introduces a new series of MEMS shock accelerometers. PCB® Series 3991/3501 MEMS shock accelerometers 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 high-g shock events. Offered in packaged and OEM configurations, these sensors are able to fulfill a variety of installation requirements.

The 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. The air-damped acceleration sensing element, which is micro-machined from silicon, is manufactured with the latest advances in etching techniques and equipment. Measuring just 2.5 x 1.7 x 0.9 mm, the sensor incorporates a seismic mass, protective over range stops, and a full-active, piezoresistive Wheatstone bridge, making it the industry's smallest, most accurate and durable shock accelerometer.

The slight air-damping reduces the resonant amplification which increases measurement accuracy. The over range stops give the sensor exceptional survivability. This is the ideal sensor for applications such as: Safe & Arm; Smart Fuzes; Penetrator Tests; Weapons Data Recorders / Launch Characteristics; Metal-to Metal Impact / Armor Piercing; Blast Loading of Structures; Drop testing; Pile Driving; Jack Hammer Testing; Down Hole Drilling; Shot Counting and more.

PCB® is offering a 50% trade up discount for any competitor's shock accelerometer or a 25% trade-up discount for any PCB® shock accelerometer on select models.
