Load cell connection.
Stainless steel beam load cell with overload stops lc501.
It converts a force such as tension compression pressure or torque into an electrical signal that can be measured and standardized.
Most load cell have four wires red black green and white.
The lc501 series of stainless steel compression load cells can withstand harsh industrial environments.
On hx711 board you will find e e a a and b b connections.
This method has the highest measurement accuracy among all load cell connection methods.
A load cell used to measure tension will not reflect negative reading if installed upside down and will result in an erroneous reading.
As the force applied to the load cell increases the electrical signal changes proportionally.
We will be using a simple arduino library to communicate with the hx711 that provides a calibration and tare reset feature to easily determine the weight of an object.
Electronic weighing machine uses load cell to measure the load or pressure produced by the load here most load cells are follows the method of strain gauge which converts the pressure force into an electrical signal these load cells have four strain gauges that are hooked up in a wheatstone bridge formation.
In this way it can not only retain the accuracy of load cell but also realize high resolution long distance transmission and quick response due to the specific extension module.
When we apply load the strain gauge resistance will change and hence the output.
Black wire to e green wire to a white wire to a.
However if the load cell is installed correctly and the readings are still negative verify the wire connection according to the color code specified by the manufacturer.
Available with 0 03 linearity in capacities from 100 to 30 000 lbf.
The most common types of load cell used are hydraulic pneumatic and strain gauge.
On the opposite side you can see the connection for the load cell.
A load cell is a force transducer.
