Abstract
A rail-monitoring element includes a carrier on which a strain sensor is attached. The strain sensor may be an optical fiber having a fiber Bragg grating. The carrier has an adhesive layer for adhesive attachment to a rail having a thermally activatable or thermally curable adhesive. The adhesive layer has a heating element having contacts for receiving electrical energy. The rail-monitoring element can be installed more easily and in a manner which saves more energy.
Claims20
A rail-monitoring element comprising:
- a carrier on which a strain sensor is attached;
- the strain sensor comprising an optical fiber having a fiber Bragg grating;
- the carrier having an adhesive layer for adhesive attachment to a rail having a thermally activatable or thermally curable adhesive;
- wherein the adhesive layer comprises a heating element having contacts that can be supplied with electrical energy;
- wherein the adhesive layer is located on the side of the carrier opposite the strain sensor.
The method for manufacturing a rail-monitoring element comprising the following steps:
- attaching a strain sensor on a first side of a flat carrier;
- applying an adhesive layer on the side of the carrier opposite the strain sensor;
- wherein a heating element having contacts for receiving electrical energy is arranged in or on the adhesive layer.
