Measuring ring for temperature measurement of piston rod, has borehole opening out with one end in outer mantel surface, and provided for insertion of temperature measuring unit, whose spikes project in innermost of recess or borehole

摘要

The ring (1) has a borehole which opens out into a recess (8) that is attached in an inner mantel surface (7). Another borehole (9) is provided for the insertion of a temperature measuring unit (10), whose spikes project in the innermost of the borehole or the recess. The borehole (9) opens out with one end in an outer mantel surface (5) and other end in the recess, where the borehole which is open is diagonally attached in a circumferential direction in the ring.
