if we applied different weight on load cell (strain gauge) how many voltage produce in load cell? please give me formula or other methods
@imran The output voltage will depend on the rated output of the load cell you are using. The load cell output is rated in millivolts per volt (mV/V) of the difference voltage at full rated load/weight. For example a 1mV/V load cell will provide 5 millivolt signal at full load when excited with 5V.
@Payam You are welcome. You can use a load cell to test the linearity of the Load Cell Amplifier Shield. For example, this 5Kg Micro Load Cell has a capacity of 5Kg and a rated output of 1mV/V(±0.15mV/V). This means that, when the load cell is excited with 3.3V and with a 5Kg load, it should output 3.3mV. You can use this to test the output of the Shield. You can connect this load cell to the shield and measure the voltage on the A0 analog pin. With a gain of 495, you should measure 1.633V on the analog pin A0 with a 5Kg load on the load cell.
hi, where is the header file located? I need the .measureforce() function for a project. thank you!
@Meaghan you can find the âWheatstoneBridge.hâ header file in the Arduino library of the Load Cell Shield here.
Will this work with the RB-Phi-203 100g Micro Load Cell. Iâd like to use this in a small low speed wind tunnel.
Hello. I am trying to connect the amplifier to Arduino mega 2560 and when I load the code it comes up with the message saying âerror compiling for board Arduino mega or mega 2560â. Does this mean that the code cannot be used for my board?
Are there any instructions how to do the calibrating with the load?
@Gabriele The Wheatstone Shield Library should work on Arduino Mega 2560 without issues. Please verify that the selected board on the Arduino IDE is âArduino Mega or Mega 2560â. Also, verify if you have correctly installed the library : Installing Arduino Library.
@Gabriele You can find instructions for the calibration + Arduino code with comments in the User Manual of the Wheatstone Shield.
am final year student of electrical engineering,My project is to design CNG and petrol indecator for fuel monetering i am use loadcell for petrol (resistive strain gauge ) and also load cell use for CNG ) with the help of Arduino and LCD display value in the form of digital ,Sir simulate this project by Proteus softweare or other softweare⊠i am wating
@imran We unfortunately donât offer consult/design services. You can show-off your project and post your questions to the robotics community in the RobotShopâs 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 canât 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 â 409 in RAW ADC. 3V at the output of the amplifier would be 3Vx1023/5V â 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
