March 7, 2013 - With damping that reduces resonance amplification and mechanical stops for over-range protection, Model 3991A112KG 2000 G, MEMS, piezoresistive shock accelerometer offers survivability to over-range, minimum zero-shift after shock, and bridge resistance. Measurement rangesof 20,000 and 60,000 G are available, andproducts are designed as drop-in mechanical replacements for legacy sensors' 2-hole screw mounting. Unitscomestandard with 10 Vdc calibration or optional user-defined values.

2000 G Sensor Features Critical Damping and High Over-Shock Survivability

Depew, NY - PCB Piezotronics, Inc., a global leader in the design and manufacture of microphones, vibration, force, torque, load, strain, and pressure sensors, as well as the pioneer of ICP technology is pleased to announce their new 2000 G MEMS, Piezoresistive Shock Accelerometer. Model 3991A112KG piezoresistive shock accelerometers represent state of the art industry technology for miniature, high-amplitude shock 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. The units feature critical damping to reduce resonance amplification and mechanical stops for over-range protection. These rugged sensors offer superior survivability to over-range, minimum zero-shift after a shock and high bridge resistance with associated lower power consumption compared to legacy sensors on the market.

The sensors are also available in 20,000 and 60,000 G measurement ranges and are designed to be drop-in mechanical replacements for legacy sensors' two-hole screw mounting. Applications include electronics impact testing, pile drivers, down-hole mineral exploration, drop testing, shot counting for firearms, sport equipment testing and pyro-shock events.

All sensing elements are micro-machined in-house at a PCB where our vertically integrated manufacturing allows complete control of product quality. Each PCB sensor is tested to its full over-shock limit prior to calibration and is supplied with a standard 10 VDC calibration or optional user defined values. Packaged and OEM surface mount configurations are offered to fulfill a variety of installation requirements. Recommended signal conditioners include Model 482C27 four-channel and Model 483C28 eight-channel ICP and DC bridge amplifiers.
