Quarter and half Wheatstone bridge extraluminal force transducers for recording of gastrointestinal motility are compared. Modification of the transducer to a quarter bridge is economical, simplifies construction, and improves longevity by eliminating the crossover wire which frequently short circuits. The quarter bridge transducer was found to be as accurate and sensitive as the half bridge transducer.
对用于记录胃肠动力的四分之一和半惠斯通电桥腔外式力传感器进行了比较。将传感器修改为四分之一电桥既经济，又简化了结构，还通过消除经常短路的交叉线提高了使用寿命。结果发现，四分之一电桥传感器与半电桥传感器一样准确和灵敏。
