On EN 5348 hand knobs with position indicator, the measuring gear is built into the knob--i.e., hand knob and indicator are one integrated unit. This makes for an esthetically pleasing design as well as a good value.
Hand knob and sight glass are all in one piece, welded ultrasonically. They are spray waterproof and corrosion proof (Protection class IP 67 according to DIN VDE 0470-1), oil and solvent proof (not suitable for alcohol).
Sight glass is resistant to shock and aging.
The pendulum system is mounted on ball bearings to give the most accurate reading, usable up to a shaft inclination angle of 60°.
The reduction gear ratio in the table shows the number of revolutions that are required by the long red pointer to make the small black pointer complete one revolution. Certain other reduction gear ratios available with minimum order quantity.

Installation Instructions:
1. Turn the shaft to the starting point (0 position).
3. Move the unmounted position indicator to the 0 position before mounting it.
4. Install the position indicator to the shaft and secure it with the set screw.
