TIMES247 replaceable pickup is a roughness sensor with the stylus that can be detached separately. The stylus and the sensor body are connected by magnetic attraction. When encountering unexpected situations such as impact, the stylus will fall off by itself, which avoids damage and improve the reliability of the sensor. At the same time, the split structure is adopted, and different types of stylus can be selected to install on the sensor body according to the shape and size of the workpiece to be tested, which improves the versatility of the sensor. The sensor adopts a skidless design and can work with TIME3231/TIME3233/TIME3234 roughness measuring instruments. It greatly reduces the cost for you.
