Sea Data Corporation Introduces Deep Sea Instrumentation Cable

—Literature Available A new instrumentation cable, specifically designed to meet the needs of submersible instrumentation systems has been introduced by Sea Data Corporation of Newton, Mass.

The company announced the availability of the cable with strain and waterproof molded connectors to meet individual requirements.

The new cable is built around a Kevlar core strength member manufactured by Philadelphia Resins, which is symetrically braided to minimize stretching and twisting. Break strength is 6,000 pounds with a working tension of 1,200 pounds. A dacron jacket and extruded polyurethane layer separate the core from 21 color coded No. 20 FEP insulated conductors. The conductor layer is covered with a foil shield and mylar wrap after which a heavy polyurethane jacket is applied.

The finished cable is flexible, lightweight, 565 inches in diameter and can be supplied in lengths up to 2,000 m. Temperature, conductivity and similar sensors can be readily spliced into the polyurethane jacket, affording the opportunity for easily achieved leak-proof molded joints, with smooth contours to minimize snagging.

The Sea Data Thermistor Chain is a typical application. In addition to the thermistor chain, and finished cable with custom terminations, with or without sensors molded in at the factory, raw lengths of the cable can also be purchased.
