Position: Monitoring container load weight is challenging and needs to be accurate to help transportation companies manage costs and ensure & regulatory compliance. Retrofitting weighing systems is an expensive and time consuming job. Now there is an easily installed wireless solution
The Weighing Problem:
Industrial Weighing companies facing new legislative and environmental issues have to look at spreading the costs associated with such change. This has meant a tighter control on the total filled weight of containers. Any excess weight in the container has to be accounted for and charged accordingly.Modifications to existing container vehicles can be a costly and lengthy process. Vehicles can be out of service for several days and have to undergo expensive, labour intensive, welding.
The Wireless Weighing Solution:
A container loader truck is fitted with two miniature T24-SA wireless strain gauge acquisition weighing modules contained in shackles which are connected to standard chains. A T24-HA wireless handheld display is used to sleep and wake the T24-SA devices and provide a summed display from the two acquisition devices. The handheld offers Gross/Zero toggling of the display so it can be zeroed just before each customer's refuse is added to the skip. In this weighing system a printed paper-ticket is required on the spot for the customer. A T24-SO serial output module triggered from a key-press on the handheld and connected to a thermal printer, prints a ticket containing company information and the net weight of the refuse along with a log number. The printer and T24-SO are neatly housed in the truck cab. An optional module for the T24-SO would allow the ticket to contain time and date. Using a single 3.6V Lithium battery (Saft LSH20) per T24-SA, a life of three years can be achieved when the system is used for twenty pick-ups per day where each pick-up involves the industrial weighing system being active for ten minutes.
