Original designcode: MBT.50/GA11/MBT.70/GA12
Product description
On knurled control knobs with position indicator EN 5348, 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.
Furthermore hand knob, pointer spindle and sight glass are manufactured as one integrated unit and ultrasonically welded. They are absolutely leak tight against spray water and corrosion proof (protection to IP 67).
The gravity drive 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 arm to make the short black pointer arm complete one revolution.
Installation instructions
- Turn the shaft to the starting point (0 position)
- Move the unmounted position indicator to the 0 position before mounting it
- Install the position indicator to the shaft and secure it with the set screw
