Delphi High g Three Axis Accelerometers
;)
The Delphi High g Three Axis Accelerometers provide users with a small yet robust mechanically packaged accelerometer set for measuring dynamic forces in all three axes. They are available in a variety of ranges including the following:
- 35 g
- 50 g
- 70 g
- 120 g
- 250 g
Benefits
- Precisely measure dynamic forces
- Highly rugged design for motorsports applications
- Variety of ranges available for application flexibility
Typical Applications
Delphi High g Three Axis Accelerometers can be used for race car suspension measurements, racing accident measurements and industrial use. The 250 g part is currently being used by FORMULA 1™ as a crash sensor and also by National Hot Rod Association (NHRA®). The 35 g part is currently being used by IndyCar© as a hub sensor.
