Overview
The NCAP pedestrian impact test sensor is a critically fluid damped accelerometer designed specifically for ATD pedestrian impact and head form testing.

The accelerometer has been certified by Euro NCAP for dummy impact and head form test applications and is available in ranges from ±50g to ±2000g. It features silicon semiconductor strain gages in a half-bridge configuration with a nominal 1500Ω impedance. The design also incorporates integral mechanical over-range stops for high-g protection. The model EGAS-S398C accelerometer is temperature compensated for low drift performance. The thermal compensation circuit is installed in an in-line cable module.
