Description
The PhidgetBridge 4-Input is a load cell interface. It amplifies the signal from a load cell and provides a clean, stable digital value.
After connecting the interface to a computer through USB, you will be able to measure the output of up to four load cells. Applying calibration parameters will allow you to convert the raw load cell measurement into an accurate weight or force measurement.
Need a simple weight scale? Connect this interface to the Weighing Scale Kit and get started!
Features
- Maximum data rate of 1200Hz
- High-resolution 24-bit ADC (analog-to-digital converter)
- Configurable gain (1x, 8x, 16x, 32x, 64x, 128x)
- Four load cell inputs
