@imran We unfortunately don’t offer consult/design services. You can show-off your project and post your questions to the robotics community in the RobotShop’s forum.
sir i am final year eng student my project on( load cell and pressure sensor and arduino), sir please suggest best simulation softweare for this project and recommended notes for this(load cell, pressure sensor both are resistive tranducer ) also explain calculation of load cell?
@imran All the information/calculations you need can be found in the Load Cell Amplifer Shield documentations
is it possible to house this sensor 2/4 feet beneath surface?
sir,
i want ask a question, 2v or 3v across the amplifier what is value in 10bit ADC in LCD in gram or kg please write for formula?
@Timothy We can’t guarantee that the load cell will function properly when buried 2/4 feet beneath surface. There is no IP ratings on the load cells we offer, therefore burying the load cell might damage it.
@imran 2V at the output of the amplifier would be 2Vx1023/5V ≈ 409 in RAW ADC. 3V at the output of the amplifier would be 3Vx1023/5V ≈ 614 in RAW ADC.
HI,
my need is to measure very minute level of strain, using strain gauge. i would like to measure strain as low as one or two micro strain. is it possible to use this board for such procession task? Is there any temperature sensor, where we can compensate temperature effect? my other option would be to use temperature sensor and connect directly to ardunio.
thanks
Can the load cell shield with compatible(stacked) on Arduino AT Mega328p?
how to convert 614 in RAW ADC to gram or kg to show LCD display?
@Raj Please take a look at our Temperature Sensors section. The Load Cell Shield doesn’t have a built-in temperature sensor/compensation.
You are correct, The temperature sensor would be connected on your Arduino board. It can be connected through the Load Cell Shield when it’s stacked on the Arduino Board. And please remember that the Load Cell Shield uses A0 and A1 pins on the Arduino, therefore if you are planning to use an analog temperature sensor, you might need to connect it to a different analog pin than A0 and A1.
To connect a Strain Gauge to the Load Cell Shield, you might need to create a Wheatstone bridge configuration (Quarter, Half or Full bridge depending on your application).
@Arjun Yes the Load Cell Shield can be stacked on an Arduino UNO (based on the ATMega328P) as explained in the tutorial.
Hello! Can I use other load cells with load cell shield? Other cells include 200kg button load cell and 500kg s-type load cell in your company and other companies’ product
@Seunghoo Yes S-Type Load Cells can also be used with the Load Cell Shield, same as Micro Load Cells. In our Force Sensors section, you can find 100 Kg Type S Load Cell, 200 Kg Button Load Cell and 500Kg S Type Load Cell.
I’m trying to build a miniature force sensor that will have a capture rate of 5-10 Hz and deliver a graphical output, or at least multiple data points that can be later manipulated. Is this something that I can do in programming and still have a basic strain gauge or mini load cell? Looking to keep the size of the sensor to the diameter of a quarter(ish).
I have a 3-wire(black,red,white) load cell each having a capacity of 50 kg can you send me the connection diagram and the code?
@KJ You can use the Load Cell Shield interfaced with an Arduino UNO board and with the appropriate load cell. Then, you can plot the output data from the Arduino using the Processing software. This link might help you getting started.
I have a load cell that is being used by some equipment and would like to make an independent measurement of this load cell while it is being used in real time. The load cell is powered by 5 volts. I have spliced ground, signal + and signal - wires from the load cell and have them going to the RB-Onl-38. I have not connected the 5 volt load cell power to the RB-Onl-38 Vcc header pin. The nominal voltage from the load cell is 2.5 volts, well within the measurement range of the RB-Onl-38. However, the RB-Onl-38’s reading doesn’t change with the change in load pin loading. If I disconnect the load pin ground from the RB-Onl-38, then the RB-Onl-38 works - but the signal is noisy…probably from the fact that the RB-Onl-38 and load pin do not share a common ground. Could you shed some light on why the RB-Onl-38 wouldn’t work with the common ground? Much thanks.
