A transducer is a device that converts one type of energy to another, or responds to a physical parameter. A transducer is in its fundamental form a passive component. If the component is electrical then it generally has two electrical terminals.
thermistor (includes PTC resistor and NTC resistor)

Geiger-Müller tube used for measuring radioactivity.
Electronic. These components change one electrical parameter in response to another. By some definitions these are electronic components, not transducers.

Transducers with a wide beam width of up to 50° will "see" around their location at a wide section of the bottom.
Using a transducer from a 100-watt unit on a 1,000-watt unit is also not a good idea as the excessive energy from the more powerful fishfinder will soon destroy the crystals within the small transducer.
Transducers may be installed through the hull, in water- or oil-filled boxes inside certain hulls, attached to the inside of some fiberglass boats, or mounted on the transom.
As we continue our journey through the transducer we come to the other side of the diaphragm where one side of the sensor element is. The actual element is a strain gauge; that is, a resistive element whose resistance changes with the amount of strain placed on it.
One of the better ways is to suspend the submersible transducer in a perforated 1 1/2" or 2" PVC pipe or attach the transducer (using a optional 1/2" M NPT fitting) to a rigid conduit.
When mounting the transducer in a well casing, the cable hanger can be secured to a eyebolt attached to the well plate or the side of the well casing.
