Load cell connection diagram and its pinout.
Load cell connection.
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.
This method has the highest measurement accuracy among all load cell connection methods.
It converts a force such as tension compression pressure or torque into an electrical signal that can be measured and standardized.
The most common types of load cell used are hydraulic pneumatic and strain gauge.
Most load cell have four wires red black green and white.
On hx711 board you will find e e a a and b b connections.
Available with 0 03 linearity in capacities from 100 to 30 000 lbf.
The lc501 series of stainless steel compression load cells can withstand harsh industrial environments.
A load cell is a force transducer.
It converts the mv signal of load cell in specific load cell module of plc.
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.
On the opposite side you can see the connection for the load cell.
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.
A load cell used to measure tension will not reflect negative reading if installed upside down and will result in an erroneous reading.
Black wire to e green wire to a white wire to a.
Red wire to e.
When connecting a 4 wire load cell to a junction box and then the junction box to a weight indictor it is best to use a 6 wire load cell cable for the junction box to weight indicator connection this will help to compensate any voltage drops during the length of the cable between them.
Stainless steel beam load cell with overload stops lc501.
