Abstract

A method for installing a sensor on a component is provided. The method includes attaching the sensor to a surface of the component. The method includes covering the sensor using a metal wire. The method includes applying a multilayer coating on the metal wire. Applying the multilayer coating includes applying a first coating. The first coating is capable of being machined. Applying the multilayer coating includes machining the first coating and applying a second coating over the first coating. The second coating is a ceramic oxide and the second coating is configured to serve as a thermal and dielectric barrier. Applying the multilayer coating also includes applying a third coating over the second coating. The third coating is configured to provide erosion resistance.

First claim

What is claimed is:

1. A method for installing a sensor on a component, the method comprising:
providing the component, a metal wire, and the sensor;
attaching the sensor to a surface of the component;
covering the sensor by using the metal wire; and
applying a multilayer coating on the metal wire, wherein said applying the multilayer coating includes:
applying a first coating, wherein the first coating is configured for machining after the covering the sensor by the metal wire;
machining the first coating;
applying a second coating over the first coating, wherein the second coating is a ceramic oxide, the second coating configured to serve as a thermal and dielectric barrier; and
applying a third coating over the second coating, wherein the third coating is configured to provide erosion resistance.

2. The method of claim 1 , wherein said attaching the sensor to the surface of the component further includes applying an adhesive directly on the surface of the component.

3. The method of claim 1 , wherein said attaching the sensor to the surface of the component further includes tack welding the sensor to the surface of the component.

4. The method of claim 1 , wherein said covering the sensor by using the metal wire includes wrapping the metal wire around the sensor.

5. The method of claim 1 , wherein the sensor is a strain gauge.

6. The method of claim 1 , wherein the third coating includes chromium carbide/nickel chromium.

7. The method of claim 1 , wherein the metal wire is made of tungsten.

8. The method of claim 1 , wherein the metal wire has a circular cross section.

9. The method of claim 1 , wherein the component is a cylinder liner.

10. The method of claim 9 , further comprising attaching a plurality of strain gauges on an outer circumference of the cylinder liner, and wrapping the metal wire around the outer circumference of the cylinder liner so as to cover the plurality of strain gauges.
