Problem with using a single point load cell

[arslankhalid]

we want information about using a single point LOAD CELL
it is a load sensor. No matter how much load we apply the change in the reading remains negligable, the maker is TEDEA HUNTLEIGH model 1022. READING ALSO GOES NEGATIVE.

Re: LOAD CELL

More info is needed to help you. Please answer the following:

What excitation are you applying to it?

What type of circuitry are you measuring it with?

How is it wired to the measurement circuit?

How are you loading it?

LOAD CELL

Check out this specifications might help you

check that you have connected the wires correctly
if still there is problem post your circuit here

Re: LOAD CELL

Bear in mind that the output of load cells is relatively small ..
In practice, most load cells output less than 10 mV/V, that is 10 mV of output per volt of excitation voltage ..
For example, with a 10 V excitation voltage, the maximum output signal is 100 mV ..
Therefore, load cell signal conditioners include amplifiers to boost the signal level and gain amplifiers with gains of 1000 and more are not unusual ..
