Sw420 vibration sensor query

Anyone know if or how the sw420 vibration sensor can detect the vibration in a particular direction.

The idea was to attach the sensor on the lower front face of a differential housing to detect drive shaft vibration, particularly when the vibration is either throwing the shaft up (or down) at right angles to the sensor module.

Looked over the spec sheet but there seems to be very little info there.
