Weighing Scale

I'm glad it's Friday.

IC that it's Friday.

Hi Sandeep, to answer this question, it would help if you could provide some more information.

It would help if we knew the application. The weight range that the load cell has to operate over, and how you would like the information from the load cell to interface with the rest of the machine.

Cheers

Joe

Dear Joe,

Weight range is 6kg to 30kg. I would like to know which part is converting load cell signal to digital display signal. Which part is responsible to give load cell accuracy in digital signal.

Please guide me as I am not a electronics engg.

Thanks Joe.

what are you going to do with the output?

what level of accuracy is required?

what are the operating conditions?

what is the duty cycle?

Dear Garthh,

For retail scale output is only for display and in industrial scale it is for rejection mechanisum.

Accuracy lavel is depend on custumer request +/- 5gm.

What do u mean by operating condition

consider Duty cycle.

As I told u I am not a Electronics Engg.

May be u have many doubts

Please consider specification and give me example

For example xyz accuracy what I have to do?

zyz duty cycle what I have to do?

Thanks for your Question at least I am getting some direction.

Thank u very much.

How many products are you weighing per minute?

what size are the products?

Dear Garth,

For retail scale 20 products per min

for industrial dynamic weighing scale it is 120 per min.

But dont consider industial scale.

Platform size of retail scale is 300mm x 300mm.

Regards.

Probably more important than the load cell or the output electronics is having calibrations preformed on a regular periodic basis

to do this you would need

There may be a local agency that regulates weights & measures for retail sales, who would dictate what equipment is acceptable
