휘트스톤 브릿지 모듈 -VINT용
(Wheatstone Bridge Phidget)
개요
- Bridge 기반의 센서는 매우 흔한 타입의 저항식 센서입니다.
- 로드셀, strain gauge, 압력센서, 피에조 센서들이 보통 bridge 기반의 센서인데, 이런 센서의 작은 전압 변화를 측정하려면 Wheatstone bridge 입력이 필요합니다.
- 본 제품은 고분해능의 ADC를 사용한 제품으로 2개의 wheatstone bridge 입력을 받을 수 있습니다.
Accurate and Adjustable
This board is equipped with a 24-bit analog to digital converter, resulting in accurate measurements at resolutions as high as 59.6 µV/V. The bridge gain can be changed in software to 1, 2, 64, or 128, allowing you to get the best resolution for the range of the sensor you use. An error event will be launched whenever the measurement value saturates, so your program can dynamically change the gain when necessary.
