Oil level sensor tank for turbine engine
An oil tank of a turbine engine, particularly of an aircraft turbojet includes an external wall forming a generally curved main cavity. This cavity includes an arched sensor for electrically measuring the oil level, for example in a capacitive manner. Said arched sensor matches the curvature of the main cavity in order to be integrated therein. Sensor supporting arms distributed along the curvature of the arched sensor and/or an arched sleeve with an arched cavity receive the arched sensor. A turbine engine is provided with an oil tank, as well as a method for mounting a sensor in an oil tank.
1. An oil tank assembly for a turbine engine, comprising:
an external wall forming a generally curved main cavity;
an arched sensor for electrically measuring an oil level within the main cavity, said arched sensor matching the curvature of the main cavity; and
an arched sleeve within which the arched sensor is disposed, wherein the sleeve is hinged through pivot connections.
2. Assembly according to claim 1 , wherein the sleeve is directly connected to the external wall.
3. An oil tank assembly for a turbine engine, comprising:
an external wall forming a generally curved main cavity;
an arched sensor for electrically measuring an oil level within the main cavity, said arched sensor matching the curvature of the main cavity; and
an arched sleeve within which the arched sensor is disposed, wherein the sleeve comprises:
cut-outs, wherein the cut-outs divide the sleeve into several segments that are mobile with respect to one another.
4. Assembly according to claim 3 , wherein the sleeve is directly connected to the external wall.
5. Method for mounting a liquid level sensor in a tank of a turbine engine, the method comprising:
(a) providing a tank with an external wall forming a generally curved main cavity;
(b) providing an electrical, level measuring sensor that is arched along a radius of curvature, and disposing sensor supporting arms or an arched sleeve inside the main cavity;
(c) inserting the sensor into the cavity while contacting the sensor supporting arms and/or with the arched sleeve such as to match the curvature of the cavity,
wherein during the insertion step (c), the sensor retains its radius of curvature.
6. Method according to claim 5 , wherein the tank comprises an opening, particularly a filling upper opening, and during the insertion step (c), the arched sensor is inserted via said opening.
