Hence they are good value for money. In addition they impress by their good design. Furthermore hand knob, pointer spindle and sight glass are manufactu- red as one integrated unit and ultrasonically welded. They are absolute- ly leak tight against spray water and corrosion proof (protection to IP67). The pendulum system is fitted with ball bearings to give a precise reading and it can be used in temperatures of up to 60° with suitable spindles. The reduction gear ratio shows the number of revolutions that are requi- red by the long red pointer to make the small black pointer complete one resolution. see also... • More Information to Position Indicators GN 000.8 → Page 366 • Clamping Elements GN 826 (for Adjustable Spindles) → Page 346 Installation sequence 1. Turn the spindle to the starting point (0-position). 2. Move the unmounted hand knob to the 0-position. 3. Install the position indicator to the spindle and fix it with the screw.
