Abstract
The temperature sensor can have a core having a length extending between two ends, the core having a cavity extending along the length, a wire extending in the cavity, along the length, the wire fixed at both ends, the core having a transversal aperture at an intermediary location between the ends, the transversal aperture leading into the cavity, and a potting filling a portion of the cavity and supporting the wire at the intermediary location of the transversal aperture.
Claims19
A temperature sensor comprising a core having a length extending between a first end and a second end, the core having a cavity extending along the length, a wire extending in the cavity, along the length, the wire fixed at the first end and at the second end, the core having a transversal aperture at an intermediary location between the ends, the transversal aperture leading into the cavity, and a potting filling a portion of the cavity and supporting the wire at the intermediary location of the transversal aperture.
A method of making a temperature sensor, the method comprising:
- introducing material into a gap between a wire of the sensor and an inner wall of a core of the sensor, via a transversal aperture in the core;
- said material holding a portion of the wire relative to the core thereafter;
- and
- wrapping a sensing coil around the core, and connecting one end of the sensing coil to a corresponding end of the wire.
A gas turbine engine comprising a temperature sensor, the temperature sensor comprising a core having a length extending between two ends, the core having a cavity extending along the length, a wire extending in the cavity, along the length, the wire fixed at both ends, the core having a transversal aperture at an intermediary location between the ends, the transversal aperture leading into the cavity, and a potting filling a portion of the cavity and supporting the wire at the intermediary location of the transversal aperture.
