Torque meter data reading by Arduino

Dear friends. I am working with a Torque Meter TQR-600NF65M3. The shaft rotation is read by the magnetic sensor which is amplified by stain gauge and converted analogue to digital and read the data in the computer. However, I want to use the Arduino to read the data. I appreciate your help in advising me how to implement my project.

Sure. What have you tried and what are the results?

Google can't find your product number. Do you have any other information?

Picture would be much more informative if you zoomed in on the torque meter's data plate, in good light and focus of course.

Actually the torque meter is bit old. The last it was used on 2008. Almost 10 years later I am using it. The torque meter has two sensor. One is for rpm and another is magnetic torque sensor. The torque model is TQR-600NF65M3. The torque magnetometer model is MP-981.The magnetometer is connected to the amplifier TYPE 312. The amplifier is connected to the A/D converter AK-V1, V00040. The other part of the A/D converter is attached the PC USB. However, the software to read data is not working. The software can not be installed in the PC. It can be used real time from the DVD. Since the software shows message for error I can not read the data.

I want to use Arduino UNO for reading the data. Please give me some suggestion regarding the hardware connection and also the coding.

Thank you very much for helping me. You people are so cooperative than I thought.

You state: "It can be used real time from the DVD. Since the software shows message for error I can not read the data. ".

But you want to read the bad data from an Arduino. Isn't the next step to find the error and correct it, so you then will not have the same error on the Arduino?

Thank you Mr. Paul, Since the software is not working I do not know how to fix the software. But I still have the hardware arrangement. In my understanding the arduino coding can be used to read the voltage and converting to Torque.

Here is my update what have I done so far:

I connect the Troque sensor output to amplifier input. Amplifier gives a reading of +- 280 mV (Max) while connected to Oscilloscope. However I rotate the shaft with a motor of 720 rpm but the oscilloscope reading makes no changes. I am afraid if the sensor is okay or not. Please let me know if you have any suggestion.

Thanks.

That tells me you are either not powering the sensor correctly or it is truly broken.

Mr. Paul, I checked the torque meter in terms of amp reading. Today I see the amp changing. Actually I force the two side open shaft in two different side and got the amp changing. It means the sensor is okay. Before I tried the motor to run the shaft but there was no load or resistance so no changing in amp.

Here is my thinking now.

I connect the torque sensor to the amplifier. amplifier output to the arduino analogue pin to measure the amp.

Is it okay.

Then I will be need of to write a program for converting amp to torque.

How does look my idea?

I think you are almost 100% with the project! However, the +_280 mv will be a problem because the Arduino cannot measure negative voltages.

Perhaps someone more experienced with the a/d part of the Arduino can suggest a solution.

Me.Paul I got the voltage reading as well. I connected the torque sensor with strain gauge and output to the arduino board. Because the arduino can read until 5 volt without a/d converter so initially I got 0.14 V reading which I also checked by multimeter found same. However the exciting fact is that for voltage conversion to torque I measured V changing with different load and measured the Torque manually. Tomorrow I will calibrate for final conversion. If you have any suggestion let me know.
