Ina125 Load Cell Circuit

Hello i m hoping someone could help point us in the right direction on this issue.

Ina125 load cell circuit.

We ve gotten the circuit to perform well with one load cell but are having issues getting the expected output with the other. Demo of the ina125 with a 50kg load cell on a breadboard. It provides complete bridge excitation and precision dif ferential input amplification on a single integrated circuit. Excitation white.

The ina125 is laser trimmed for low offset. Load cell interfacing schematic. The ina125 is a 16 pin dip dual inline package ic. Pin 15 and 4 aren t connected for a start and there were a few other.

It has two stages of amplifier with reference amplifier. Demo of the ina125 with a 50kg load cell on a breadboard. The most difficult part will be connecting the load cell if a pin connector crimping kit is not available. A single external resistor sets any gain from 4 to 10 000.

The ina125 is a low power high accuracy instrumen tation amplifier with a precision voltage reference. Arduino load cell circuit with texas instruments ina125 instrumental amplifier updated 23 11 13 the circuit is simple enough to create on a breadboard as shown in the picture above.

Connect load cell pins to the instrumentation amplifier as shown in the schematic diagram.

Signal green. Signal black. The load cell output needed converting into a digital input using an aanalogue to digital converter adc which i covered in my previous post.
