一、非电量的电测法概述 土木工程(包括路面工程)检测中,除机械式测量外,还广泛应用非电量的电测法进行各种力学参数的测定。 所谓非电量的电测法,是把需要检测的非电量(如应力、应变和位移等),通过一种器件转换成电学童(如电阻、电容、电感、电压等),然后采用各种电磁仪表进行测量,并按一定关系换算成力学参数的量测方法,简称为电测法。其中把非电量转换成电学量的器件称为传感器。
First, the non-electric measurement method Overview civil engineering (including pavement engineering) testing, in addition to mechanical measurements, but also widely used non-electric measurement method for the determination of various mechanical parameters. The so-called non-electricity measurement method is to detect non-electricity (such as stress, strain and displacement, etc.) through a device into electrical children (such as resistance, capacitance, inductance, voltage, etc.), and then use a variety of electromagnetic Instrument to measure, according to a certain relationship between the conversion of mechanical parameters measurement method, referred to as the electrical measurement method. The device that converts non-electricity to electricity is called a sensor.
