Available with 0 03 linearity in capacities from 100 to 30 000 lbf.
Load cell connection.
Black wire to e green wire to a white wire to a.
Most load cell have four wires red black green and white.
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.
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.
A load cell is a force transducer.
This method has the highest measurement accuracy among all load cell connection methods.
On hx711 board you will find e e a a and b b connections.
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.
As the force applied to the load cell increases the electrical signal changes proportionally.
Load cell connection diagram and its pinout.
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.
The lc501 series of stainless steel compression load cells can withstand harsh industrial environments.
It converts the mv signal of load cell in specific load cell module of plc.
Red wire to e.
It converts a force such as tension compression pressure or torque into an electrical signal that can be measured and standardized.
When we apply load the strain gauge resistance will change and hence the output.
Stainless steel beam load cell with overload stops lc501.
The most common types of load cell used are hydraulic pneumatic and strain gauge.
