Wireless Platform Weighing With Ticket Printing

A weigh platform is used to weigh items being loaded into a truck. Items are first stacked onto the weigh platform and the displayed weight watched until a limit is reached or all items are stacked. A ticket is then printed in duplicate, giving the truck driver and the loading company a written record of load weight and time and date.dump truck

The Problem:

The weigh platform consists of four load cells and the customer wants to minimize wiring which can be damaged by trucks or the platform movement itself.

The Solution:

A T24-SA telemetry strain gauge acquisition mounted in a sealed case with internal batteries ( 2 X Duracell Alkaline DCells) is mounted near each loadcell with the device transmitting the data at a rate of one per second. This gives a battery life of one year without having to turn off or sleep the measurement modules. A T24-SO serial out device sums the weight from these four sensors and displays the result on a large easily viewed LED display.

A thermal printer module, which houses a radio telemetry printer and display driver T24-SO and a real-time clock module, also monitors the sensor data and prints two tickets containing the time, date and total weight along with company information. The printout is triggered by a push switch.
