This null-balance system is usually more accurate than the direct-readout bridge . 这种调零系统通常比直读电桥更精确。
Resistance thermometer bridges may be excited from either a-c or d-c sources . 电阻温度计电桥的供电可以是交流电源,也可以是直流电源。
Ammeter, voltmeter, bridge and similar common methods are typical equipment types . 电流表、电压表、电桥以及类似的常见仪器都属于常用的设备。
The bonded-foil gage monitored with a wheatstone bridge has become a highly perfected measuring system . 用惠斯登电桥监测的粘贴箔式应变片已成为高度完善的测量系统。
It is important to keep the bridge voltage low in order to avoid a self-heating of the measuring element by the bridge current . 保持电桥低电压很重要,以避免桥路电流测量元件自热。
