Breaking a l ignment m e a s u r e m e n t barriers

tb-/iftechnik has made what it calls a b reak through in rapid a l i g n m e n t of seve re ly misa - l igned mach ines even over d i s t ances of 20 m or more, where jus t slight misa l ignment causes any laser beam to leave its sensor as the shaf ts are turned.

How about a sensor, then, of inf ini te size? Pr/ i f technik has now perfected a s imple method, known as Inf in i range, which effectively e l iminates the range l imi ta t ions tha t p lague less-so phis t ica ted laser a l ignment sen- sors: the sTstem p rompt s the user to readjus t the beam in mid-measurement .

Rosenbauer has jus t launched a new compac t p u m p unit called t h e Ot te r . " C o m p a c t , l ight , powerful, and good value" was the design brief, and the resul t fea tures an 18 hp Briggs & St ra t ton 4-stroke motor, driving a single-stage Rosenbauer cen- t r i fugal p u m p wi th 3-dimen- s i o n a l l y c u r v e d i m p e l l e r , diffusor and spiral housing.

The shaft is sealed by a zero- m a i n t e n a n c e s l iding-r ing seal tha t is res is tant to dirty water, is safe to r u n d ry a n d is p r e s s u r e - h a m m e r - p r o o f . A hand-ac tua ted l ightweight pis- ton pr iming p u m p is provided, and the p r o t e c t i v e ca r ry ing frame has 4 swing out handles, making the PFP easy to carry. Output at 3 m suct ion height is up to 1000 lpm.
