VINT Wheatstone Bridge Bridge-based Sensor High-resolution ADC Analog to Digital Converter

The Phidget VINT-Wheatstone bridge sensor interface is a common type of resistive sensor that produces a very low voltage drop. Wäge cells, strain gages, pressure sensors and piezoelectric sensors are examples of sensors that normally operate in this way.

- Übliche type of resistive sensor
- Generates a very small voltage drop
- Equipped with a 24-bit analog-to-digital converter
- Uses a high-resolution ADC to read up to two signals and connect them to each VINT port

This card is equipped with a 24-bit analog-to-digital converter, which results in accurate measurements at resolutions up to 59.6mu;V / V. The bridge amplification can be changed in the software to 1, 2, 64 or 128 so that you get the best resolution for the range of sensor used. An error event is always triggered when the reading is positive so that your program can dynamically change the gain as needed.
