A half bridge composed of a working resistor and a compensation resistor is connected to the measuring circuit with a connecting wire. When the stress is close to the fracture stress of the sample, the ultrasonic signal begins to weaken obviously due to the structural change of the sample. The above sensor composed of triode group can send discontinuous signals. It is suitable for equipping various measuring and inspection instruments. The instruments and sensors are produced by talinsky test instrument factory. The hydrometer method is based on akilaide principle and uses floating buoy or immersion buoy as sensor. It is understood that some types of automatic densitometers work according to the principle of pyknometer method. In the abrasive industry, it is necessary to inspect and measure the humidity when manufacturing organic bond abrasive tools.
