Monitoring with magnetic ball prisms
Precise - universal - inexpensive
Our modular system of ball prisms was especially developed for monitoring applications. The major advantage of this system is its very high centring accuracy of ± 0.1mm and an opportunity of targeting the same prism from various viewing angles without any loss in accuracy. These prisms are also very inexpensive.
The prisms consist of a galvanised steel ball manufactured to a tolerance of ± 0.05mm and a triple prism inserted exactly in its centre.
The system is completed by a ball base and centring plates, which are adapted to the specific mounting situation and may be reliably fixed on almost any surface by adhesive bonding or screwing/dowelling.
The ball bases have integrated permanent magnets with various holding forces ensuring a reliable connection to the ball prism and the centring plate. This sophisticated design allows swivelling the prism in all directions over a range of 200 gon.
When the points to be monitored are easily accessible and when measuring intervals are long, the prisms may be mounted shortly before the measurement. As a consequence, they can be used for other projects during the interval.
In such case, only the ball base or the centring plates will remain at the object to be monitored. The base is protected against dirt and adverse weather conditions by a cover plate which is included with the product.
Note:
When using the prism on vibrating components (such as rail tracks, crane rails etc.), a base with a powerful magnet (4 or 20kg holding force) should be used in all cases, and the centring plate should be fixed by adhesive bonding.

Glass mini prisms manufactured with a high level of precision and mounted in a ball housing made of galvanised steel.
This ball base made of hard anodised aluminium features an integrated permanent magnet and is suitable for very fast and reliable mounting on all magnetic surfaces.
It is rarely possible to detach ball bases with magnetic forces of 15 and 20kg from their installation surface without using a tool.
When you want to use ball prisms with M8 wall plugs, prism rods or similar devices, our ball bases (Ø 33mm) with thread connection are the right choice.
When the magnetic ball base is not intended for permanent mounting on the object or when the installation surface is not magnetic, we recommend the use of our galvanised steel centring plates.
For the transport of your ball prisms we recommend our special cases made of shockproof
ABS plastic with foam insert.
