Page 360 | 1.4 Adjusting, Positioning, Locking with and without Position Indication Position indicators are mechanical measuring devices which indicate and monitor the movement of a machine component along a linear shaft or threaded lead spindle. They are used to move and give a read out of values such as lengths [m, mm], force [N], volumes [l], revolutions [rpm] etc. Position indicators are split into the following categories: - analog (GN 000.8 / 000.9) - digital / analog (GN 000.3 / 000.13) - digital (GN 953 / 954 / 955) - digital, electronic, LCD-display (GN 9053 / GN 9054) - digital, electronic, LCD-display, with data transmission via radio frequency (GN 9153) The movement is in most cases initiated by control systems. There is an extensive range of handwheels and hand knobs available which can be used for incorporaring position indicators in their hubs.
