To minimize the risk of cable breakage, lightning damage and electrolyses ARGUS developed a novel DATA-POWER-SWIVEL (DPS) which can handle tensions above 4 ( 10) tons. The rotary joint contains a wireless optical data port at a transfer rate of 115.2 kb/s half duplex. The serial data in- and output is a RS485, RS 422 and RS232. With RS 422 and RS485 the cable can be as long as 1,300 m depending on the cable quality (twisted pair).
Another interesting feature is the possibility of powering up instruments or charging batteries mounted on a submerged frame. The swivel contain a DC/DC converter which inducts power through an air gap (water gap). Thus the swivel galvanically isolates the floating system from the submerged part.


All moving parts utilize water-lubricated ceramic balls and plain radial bearings made of teflon and delrin. These parts can be easily replaced if worn down. Therefore the unit contain no o-ring or grease sealed bearings.


The unit can be coupled with CTERM and ADD components found on our product list.
