称重传感器实际上是一种将质量信号转变为可测量的电信号输出的装置。也被成为测力传感器 、力传感器、重量感应器等等。用传感器应先要考虑传感器所处的实际工作环境，这点对正确选用称重传感器至关重要，它关系到传感器能否正常工作以及它的安全和使用寿命，乃至整个衡器 的可靠性和安全性。在称重传感器主要技术指标的基本概念和评价方法上，新旧国标有质的差异。主要有S型、悬臂型、轮辐式、板环式、膜盒式、桥式、柱筒式等几种样式。

称重传感器检测电路的功能是把电阻应变片的电阻变化转变为电压输出。因为惠斯登电桥具有很多优点，如可以抑制温度变化的影响，可以抑制侧向力干扰，可以比较方便的解决称重传感器的补偿问题等，所以惠斯登电桥在称重传感器中得到了广泛的应用。 因为全桥式等臂电桥的灵敏度zui高，各臂参数*，各种干扰的影响容易相互抵销，所以称重传感器均采用全桥式等臂电桥。
