Strain gauge schematic

Hi, I just received a strain gauge amplifier, looks good but the schematic in the user manual is hardly legible. Can I get a better copy?

Thanks in advance,
Jim

Hi,

Could you please specify which product ? (Product code or link)

Thank you,

Hi,

A clearer Schematic has been added to the documentation of the Shield.
We hope this helps.

Regards,

The specifications from the strain gauge amplifier are good to work with, especially if you are using an Arduino UNO board – as already stated in the datasheet specifications from the website you posted. I will suggest that you work with what you have. You can measure the voltage output of the gauge – using a very sensitive voltmeter – at the rated maximum load, then adjust the amplifier’s gain with an external resistor. You can learn more about working with amplifiers and strain gauges here: https://tacunasystems.com/knowledge-base/. Ensure that whatever output you get, it should not exceed what the microcontroller/processor can handle as an input.

The links to the schematic in this post are broken. I could really use a schematic for this board so that I can figure out which pin is pin1 on the MTA connectors.

Assuming that the square pin is pin 1 when I ohm it to GND I measure 2.5K Ohms. The 4 the pin in this assumption when ohming to GND is 0.0 Ohms. So I think the square pad is pin 1.
