Breaking detector for shear pin

A system for detecting breaking of shear pins that include respective central bores, comprising:

• a number of detectors, wherein the detectors include:
• an electrically conductive element forming an elongated loop extending on a length of the bore of the shear pin and having upper ends defining contact surfaces adjacent each other;
• an electrically insulating element extending in the loop;
• power supply cables connected respectively to the contact surfaces and provided with connectors;
• and
• an electrically insulating means for removably supporting the elements of the detector in the bore of the shear pin, and
• an identification circuit including a light indicator connected between the contact surfaces, the light indicator projecting at an upper end of the means for supporting, wherein the detectors are connected in series with one another by their connectors, the detectors being respectively inserted in the bores of the shear pins;
• a power supply source connected in series with the detectors;
• and
• a warning element connected between the source and the detectors, responsive to a breakage of the conductive element of one of the detectors caused by a breaking of a corresponding one of the shear pins.

Breaking detector for a shear pin having a central bore, comprising:

• an electrically conductive element forming an elongated loop extending on a length of the bore of the shear pin and having upper ends defining contact surfaces adjacent each other;
• an electrically insulating element extending in the loop;
• power supply cables connected respectively to the contact surfaces and provided with connectors;
• and
• an electrically insulating means for removably supporting the elements of the detector in the bore of the shear pin,
• wherein the means for supporting comprises a tube insertable in the bore of the shear pin, the elements of the detector extending in the tube, wherein an insulating material is injected in the tube.
