ABSTRACT:
An encapsulated measuring system includes a follower coupled to a scanning unit which extends through a slit in a housing of the measuring system. This slit is sealed against lubricants and coolants by a pair of multipart sealing elements. Each multipart sealing element includes a sealing profile proper, along with a supporting element. The sealing profiles perform the sealing function, and the supporting elements provide the necessary permanent elasticity and stability of form. Because of this division of function, the sealing profiles themselves can be made of materials that are resistant to aggressive media such as lubricants and coolants, but themselves do not provide sufficient elasticity or stability of form to be used alone.
