I have to design the weigh in motion system.I need to take weight of vehicle moving at the speed of 40-60kmph which can have the weight of 20 to 30 ton.Can anyone suggest ADC suitable for this application
For weight measurement of an object that is not moving , it usually recommended to use Sigma Delta ADCs because of its high resolution 24bits to 32 bits. In your case, the object is moving and measure its weight while in motion. A high resolution and fast ADC must be use. For precision measurement there is SAR ADCs which are faster and far as I know the highest resolution in the market is 20bit. Newer Sigma Delta ADCs are 24 bit and has high bandwidth. You can refer to this link and do a parametric search. I am attaching a short list of some ADC that you may want to look at. By the way what sensor are you using with the application? The voltage output range of the sensor can help also determine the suitable ADC for the application.
Thanks for reply. I am using the load cell sensor with sensitivity 2mV/V with excitation voltage of 5 V.
