Force Sensing Resistor 100-120 lbs

Hi
I'm looking for the FSR (Force Sensing Resistor) that they can work with a range of 100-120 lbs (444-520 N). I can't find them on the internet. Can anyone suggest me something about them ? Thank you

They are up to 10kg, perhaps that has to do with the way they are mechanically constructed.

Do you have to use FSR ?
Does it have to be accurate ? If not, perhaps you can build something yourself. I tried using "Scotch 13 3M electrical semi-conductive tape" between two copper layers and added about 200kg, but the results are not consistant.

A Load Cell can measure heavy things, and they are also very accurate. You do need an OpAmp for a Load Cell.

120 lbs = 54 kg
