The collision force wall is a key equipment in the field of automotive collision compatibility, and the collision force wall sensor measures the collision force in the XYZ three directions. SRI's collision force wall sensors are divided into two categories: the standard version and the lightweight version. The range of the sensor covers the range of 50KN to 400KN, with a length and width of 125mm * 125mm. Lightweight MPDB collision force wall: installed on a mobile barrier vehicle, suitable for two vehicle collision MPDB testing; Standard frontal collision force wall: suitable for frontal 100% collision testing.

The standard model is divided into two types: S989C/S989A1, with a weight of 9.2kg, used for rigid frontal collision testing.

The lightweight model is S989B1, weighing only 3.9kg, making it particularly suitable for MPDB testing.
