TESTING & DEVELOPMENT

TEST & MEASUREMENT PRODUCTS - Motion Tree

Motion Tree is a sensor cluster designed to measure vehicular motion in either four or six degrees of freedom. Utilizing three linear accelerometers and up to three angular rate transducers, Motion Tree acquires an array of motion data to complete your analysis package. Motion Tree sensors are mounted at the base of a single tree-like stand that easily mounts in your test vehicle.

The Platform includes:
- Extension pole with left/right screws to form a rigidly mounted sensor cluster
- Universal mounting typically center in the vehicle
- The sensor platform employs a bubble level and jacks to create a level platform.
