| 3. | So can amount of displacement measured comes with hall1 s component it has small inertia , respond and wait for the characteristic quickly , except that hall must move with the unit under test in succession component , there are not other activity parts , so can avoid the disadvantages , such as frictional force , mechanical breakdown , etc . , adapt to doing the on - the - spot trends to test very much 因此可以用霍尔元件来测量位移量。它具有惯性小,响应快等特点,除了霍尔元件须与被测部件连动外,无其他活动部件,因此可避免摩擦力、机械故障等弊病,很适应做现场动态测试。 |
