High-precision non-contact displacement sensors

The Measuring Division of Kaman Precision Products, Inc.’s Advanced Magnetic Sensing (AMS) family of high-precision non-contact displacement sensors are specifically designed for the oil, gas, and subsea condition monitoring markets. These sensors are engineered to operate reliably in high-pressure environments ranging from 500psi to 40,000psi, making them ideal for critical applications in subsea and oil and gas operations.

Kaman’s AMS sensors significantly enhance condition monitoring systems by accurately measuring and monitoring runout, speed, and changes in machine vibration profiles. This capability is crucial for reducing risk, minimizing damage, and preventing unplanned downtime due to unexpected failures in oil, gas, and subsea environments. The sensors are also well-suited for non-contact speed sensing, shaft runout, and gear tooth condition monitoring, as well as surface finish thickness inspection and crack and defect detection.

A key advantage of Kaman’s AMS sensors is their non-contact measurement capability, which reduces wear and tear, thereby increasing sensor longevity in harsh environments. Additionally, these sensors operate without the need for special magnets, simplifying installation and reducing costs in complex subsea systems. The sensors detect target positions through non-magnetic, conductive, and non-conductive barriers, enabling leak-proof, penetrator-free equipment instrumentation installations.

Designed to withstand the demanding conditions of subsea applications, the AMS sensors are IP-67 rated and available with a variety of hermetic options, providing essential protection against water ingress. They come in standard configurations, including threaded, flanged, AS4320 pressure port compatible, and bolt head styles, and can be easily customised to meet specific OEM integration requirements.
