Alliance Sensors group has introduced its new product, the SS-7 series LVIT (Linear Variable Inductive Transducer), which is specifically designed for subsea environments and the harsh demands of the oil and gas industry.
The SS-7 is designed to be embedded into a hydraulic cylinder and utilizes the gun-drilled piston rod as a target, sensing its position without the need for a magnet. The SS-7 series can be submerged to a depth of 12,000 ft or installed in a PBOF (pressure balanced oil filled) chamber to provide position feedback on Blow Out preventers, ROVs and relief valves.
The new LVIT has uses 316 stainless steel for its 25mm diameter housing and has measurement ranges from 1 to 24 inches (25 to 600mm). SS-7 sensors use a simple coil design rather than “time-of-flight” technology or resistive film. They are based on contactless LVIT inductive sensing technology that employs a solid probe construction style, which requires only a simple conductive tubular target or a small diameter gun drilled hole in the cylinder rod for operation rather than needing a permanent magnet ring or some other type of special target.
