Alliance Sensors Group introduces the SS-7 series Linear Variable Inductive Transducer (LVIT) designed for subsea environments and the demands of oil and gas exploration. The sensor is designed to be embedded into a hydraulic cylinder and utilizes the gun-drilled piston rod as a target, sensing it’s position with-out 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.
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. Features include:
- The use of a piston rod as target
- 316 Stainless Steel 25mm diameter housing
- Measurement ranges from 1 to 24 inches (25 to 600 mm)
- Operates to 5200 psi or 12,000 feet (3000 m) depth
- Contactless; no wear-out
- DC voltage or current analog output
- SenSet Field Adjustable Scaling
