Each sensor assembly comprises a housing assembly and a shaft disposed therein. The sensor assembly comprises a sensor housing, a cylinder housing and a cylinder. A load cell sensor is generally disposed within the sensor housing and is operatively disposed adjacent to the shaft such that it may engage the sensor and cause an upward deflection that generates a stress indicative of the weight of the unit of luggage being transferred to the particular, corresponding wheel. The cylinder housing is disposed below the sensor housing and encloses the cylinder, which itself encloses the shaft. A frictional resistance between the shaft and the cylinder permits a controlled movement of the shaft therein and permits a processing unit to ascertain a corresponding weight reading.
