Anyone experiment with Omega load cell LCMFL?

Hi,

I would like to ask if any have experiment with Omega load cell LCMFL series? By some reasons, I cannot get any response from the load cell. So I need help.

In my project I have a load cell LCMFL 20N connect with NI 9237 card. I set it up with full bridge (verify with customer service), internal, 5 V excitation. The scale is 10N 1mV/V. I cannot get any response from it.

Then I tried to connect it with a 5VDC power supply and use multimeter to measure but the response signal is not changed either. So I wonder if I do anything wrong with the wiring or not.

 

Regards,

Thang Nguyen

Hello Thang,

 

The documentation found here: http://www.omega.com/Pressure/pdf/LCMFL.pdf seems to indicate that these load cells require exitation voltage on the Red and Black wires.  This is typical of most load cells.

 

I can't say for sure why your app is not working.  Have a look at the following documentation and check your wiring.

      Hi all, I new on forum and on LabView.
      I have some problem when send the sms to modem over rs232.
      In my condition, send sms is weight greater then (box) ex. 50kg and mesured value is 60kg. I received sms that is 50,11kg , every time receive the value greater of condition is, this is only when put some weight on load cell.
      Second case when the weight is present on load cell, then start the program the sms is around the final value.
      I just want to receive sms, only the final value.
      The problem is because the measured output iserted avtomatic in sms (format into string) no wait to stabilize the value.
      I apologize for my bad English
      Please help
