How to Test a Load Cell for Basic Functionality - Engineering Tips

Показать описание
A load cell is a transducer that converts force into measurable electrical output. Although there are many varieties of force sensors, strain gauge load cells are the most commonly used type.

Each load cell installation is unique as there are several types. Consult a structural engineer when your application requires very high accuracy, long-term stability, custom specifications, or when using in a varied R&D environment.

In order to gain precise weighing results, be sure to use specified load applications for load cells. Load cells have a specified load direction; do not apply side forces, bending or torsional movements on load cells. Inappropriate loading applications will risk reducing the life of load cells, plus distortion of correct measurement results.

Loved the clip. If only all presenters had the English you have, with clear accents.

When I measure the load cell I get the reading in volts and not in millivolt/volt. Why?

Hello Sir,
Have a nice day,
How can i stability test of a load cell ?
please help me.

Thank you so much for this video. I teach engineering and have a brand new (older model) Pitsco structure tester that was not working. They claimed it was the force sensor that was not working anymore and wanted to replace the entire tester for Almost 1K. Found the data sheet for tester and your video. Force tester is working fine...found out that the cable that they had running from the sensor to the onboard output/LCD screen was actually wired incorrectly! Circuit Board has connections SSEE and the sensor schematics have it SESE...It was wired SESE in the clip that connected it to the circuit board...so it was never able to read data! Wondering how many of these models were sold this way...this was not a refurbished structure tester.

Hello, we have watched few videos, in two videos the teacher denoted out-put Red wire and white wire, and in-put by green wires and black wires.
While your videos you said red and black wires use as in-put. And green and white as output . I am little confuse. Please clear my concept thanks

Thank you so much for this explanation.
I have same this type of load cell but it doesn't work. can I fix it or just replace it?

I'm thinking about making corner weight scales for a car I'm building. Is it ok to leave the weight of the car on the load cells at each corner at all times? In other words, just build the car on the scales and whenever I add weight, turn on the scales and move the load around to try to balance things out, then turn them off when not in use, but NOT remove the load of the overall car?

Just like to ask if the normal resistance value is around 350ohm, and suddendly after using the it sometime, the scale becomes dead and upon measuring the resistance of the excitation and signal becomes double. Its reading is 850ohm on excitation and 780ohm on signal. Whats the cause of it that its value double? Is the load cell damage?

Dear Sir, I have an old model of instron 2511 Load Cell which is tension and Compression type , please help me which wire color is used for comression and which one for tension .

Hi guys, how do I calibrate the cell in its factory parameters?

Thank you. I want yo read the changes in voltage during a tensile test from our load cell. But our load cell is socketed to a (R232 i think) and is not bare wire. What should i do now?

What are those tips on your volt meter called ? Those are so cool !
