What is a Contact displacement sensor?

A contact displacement sensor is a machine that can read the position of an object with a sensor. There are roughly two types of methods. LVDT method (differential transformer method) Scale method There is a similar machine called a micrometer, This is a machine operated by human hands. Since it is operated manually, the measured value may have a slight error depending on the force applied. In that respect, the contact type displacement sensor measures by the force of the internal spring, so the force is constant. One of the features is that there is no measurement error.
