This company's model SP1 string pot features a free release design that retracts the wire safely into the housing if the front connection comes unmoored, a condition Celesco terms a "cable free release." Stainless steel cable winds up along a precision machined spool which can be sized to measure lengths out to 4.75, 12.5, 25, or 50 inches. The cable can be out of line from the housing entry by as much as 45 degrees without diminishing performance. According to Celesco product marketing engineer, Jeffrey Rowe, the SP1 is of particular interest to OEMs as the transducer is good for high frequency use over many cycles. It's compact, affordable, and always in stock. More information on Celesco's OEM solutions program, visit http://rbi.ims.ca/4922-520.
NASA and Boeing developed a huge, carbon composite cryogenic fuel tank for deep space missions, and started testing it last month. The 18-ft cryotank will enable heavy-lift launch vehicles to send both humans and robots into deep space.
