Data Acquisition components for a sub-miniature load cell

[Scott J. Kramer]

Hello,

I am looking to acquire data from two sub-miniature load cells (ELFS T4-100L Measurement Specialties) simulatneously.  The FS output it 100lbs at 2.83mv/lb.   I already have LabVIEW 8.2 and have acquired data using a Analog I/0 but my signal was weak relative to the noise in the system.  I am capturing data at a high rate because the application I'm using it in involves impact.

My question is:  What amplifier/signal conditioner and DAQ combination would be the best for this aplpication? 

Thanks,

Scott Kramer

Hi Scott,

Welcome to the NI forums!  It sounds like you might be interested in the 9237 Bridge and Strain Measurement Module. The 9237 comes in a USB, Ethernet, or Wireless sleeve, or as a stand alone module for use with a cDAQ chassis.  The 9237 provides a 50ks/s/ch sample rate, as well as up to 10V of internal excitation which should reduce your system noise.  Based on what you've mentioned this is the product that I would recommend--you can find the manuals at the above links to make sure it meets all of your requirements.  Are there any additional specs that you require?

John,

Thank you for the prompt reply.  I have gotten in touch with a NI feild engineer in my area and he agreed with your suggestion for the 9237.  Thanks again.
