English Abstract
Strain gauge sensors are used extensively in industrial machines, testing equipments, and weighing indicators.
The output signal of these sensors is basically an analog voltage in the millivoltage range, and it needs to be monitored, measured, or analyzed. It is not suitable for direct input to popular analog to digital converters because of its low level, so it needs to be amplified using a suitable signal conditioner which is characterized by its precision, reliability, low power consumption, low price, and noise reduction.
Interfacing these sensors to a computer system is a challenging problem.
There are many popular solution strategies; therefore, designers must always deal with trade off among cost, accuracy, and reliability.
In this research, a real design problem is presented.
It is a rehabilitation of a Materials Testing Machine that was partially destroyed during the last war on Gaza.
Many possible solution strategies are described and the most suitable one to the case study is adopted.
We amplify the output signal from a strain gauge sensor using a precise signal conditioner designed circuit.
This amplified signal is filtered and input to a microcontroller and the value of the load is then monitored using liquid crystal display .The proposed design has been successfully implemented and the machine is returned back to work properly.
