    摘要: A probe for use with a tank having a wall pierced by an orifice and configured to contain a fluid containing paramagnetic particles. The probe comprises a magnet, a displacement system arranged at the orifice to displace the magnet from a capturing position in which the magnet is bathed in the fluid to a checking position in which the magnet is outside of the tank, and a seal ensuring the seal-tightness of the orifice in the transition from the capturing position to the checking position and vice versa.

    摘要: A filter for filtering particulates from a fluid stream includes a filter element with a filter medium and a metallic debris sensor assembly. The metallic debris sensor assembly includes a core and a coil of electrically-conductive wire. The core has a first end, a second end, and an intermediate portion interposed between the first and second ends. The first end is disposed in spaced relationship with the second end such that a measurement area is disposed therebetween. The coil of electrically-conductive wire is wound around the intermediate portion of the core. The core is adapted to generate a magnetic field in the measurement area when an electrical current is passed through the coil. At least a portion of the filter medium of the filter element is disposed within the measurement area. The filter can be incorporated into a wear detection system and used in methods of monitoring.

    摘要: A gas turbine engine can have a magnetic chip detector system with a first conductor member and a second conductor member both exposed to a lubricant flow path of the gas turbine engine, at least a first one of the conductor members including an electromagnet including a coil wrapped around a ferromagnetic core. As part of an engine shutdown procedure, an intrinsic magnetic field strength within the ferromagnetic core can be increased by circulating electrical current in the coil, and the electrical current circulation can then be interrupted for the magnetic field to remain active during engine shutdown.

    摘要: A method to effectively utilize an oil debris monitor to provide advanced warning to mechanical system failures in a high noise system by adapting detection and annunciation algorithms to the background noise in a system that includes collecting I and Q channel data from a sensor; processing the I and Q channel data to both calculate a noise based (RMS adjusted) detection threshold and to identify a ferrous and nonferrous signal; processing the ferrous and nonferrous signals to determine signal peaks above the RMS adjusted detection threshold; adjusting a detection threshold if more signal peaks observed than allowable particles in a given time window; transmitting the detection threshold previously determined to particle detection, rate limit adjustment, detectability algorithms, and estimated mass loss accumulation.
