Abstract:
A method of assembling a sensor comprising:placing a sensing apparatus within a sensor casing, wherein the sensing apparatus includes a sensing circuit having an electrical connection extending from inside the sensor casing to outside the sensing casing so that the electrical connection has an interior portion inside the sensor casing and an exterior portion outside the sensor casing, and wherein the sensing apparatus further includes a potentiometer coupled to the interior portion of the electrical connection so that an electrical characteristic of the sensor can be set from outside the sensor casing; then setting the potentiometer so that the electrical characteristic has an initial value; then sealing the sensing apparatus within the sensor casing; measuring the electrical characteristic of the sensor by use of the electrical connection; attaching a potentiometer setting apparatus to the exterior portion of the electrical connection; then operating the potentiometer setting apparatus to change as necessary the initial value to a final pre-selected value of the electrical characteristic; and then destroying the interior portion of the electrical connection.
