Abstract
A measurement system is provided that includes a probe housing, a field probe and an optical probe. The probe housing includes a sidewall, a cavity and a channel. The sidewall extends circumferentially around and axially along the cavity. The channel is radially outboard of the cavity and extends axially in the sidewall. The field probe includes a field sensor disposed in the cavity. The field sensor forms a sensor face. The optical probe is configured with an optical line of sight through the channel into a volume adjacent the sensor face.
Claims16
A measurement system, comprising:
- a probe housing including a sidewall, a cavity and a channel, the sidewall extending circumferentially around and axially along the cavity, and the channel radially outboard of the cavity and extending axially in the sidewall;
- a field probe comprising a field sensor disposed in the cavity, the field sensor forming a sensor face;
- and
- an optical probe configured with an optical line of sight through the channel into a volume adjacent the sensor face;
- the optical probe comprising an optical fiber at least partially defining the optical line of sight into the volume, the optical fiber extending axially in the channel;
- the optical probe further comprising an optical sheath, the optical sheath covering a first portion of the optical fiber and connected to the probe housing, and a second portion of the optical fiber, within the channel, projecting out from the optical sheath towards the volume.
A measurement system, comprising:
- a probe housing including a sidewall, a cavity and a channel, the sidewall extending circumferentially around and axially along the cavity, and the channel radially outboard of the cavity and extending axially in the sidewall;
- a field probe comprising a field sensor disposed in the cavity, the field sensor forming a sensor face;
- and
- an optical probe configured with an optical line of sight through the channel into a volume adjacent the sensor face;
- wherein the channel is an optical channel, and the probe housing further includes a fluid channel adjacent the optical channel within the sidewall;
- and
- wherein the fluid channel is radially outboard of the cavity and extends axially in the sidewall.
A measurement system, comprising:
- a probe housing comprising a cavity;
- a blade tip clearance measurement system comprising a first probe, the first probe comprising a first probe sensor that forms a sensor face, and the first probe sensor disposed in the cavity;
- and
- a blade time of arrival measurement system comprising a second probe, the second probe projecting through the probe housing to an end of the probe housing adjacent the sensor face, and the second probe configured discrete from the first probe.
