A leak detection sensor includes a transducer, the transducer including a base, a piezoelectric layer, and a conductive layer and at least two leads connected to the transducer. A method of making a leak detection sensor includes obtaining a transducer, the transducer including a base, a piezoelectric layer, and a conductive layer; and effecting a mounting hole such that the mounting hole is defined in the transducer. A jig includes a support and a punch. 1. A leak detection sensor comprising: a base;', 'a piezoelectric layer; and', 'a conductive layer, and, 'a transducer, the transducer defining a mounting hole, the transducer including'}at least two leads connected to the transducer;wherein the mounting hole is defined in the base, the piezoelectric layer, and the conductive layer.2. The leak detection sensor of claim 1 , wherein the base is brass.3. The leak detection sensor of claim 1 , wherein the transducer is dampened.4.
