"The ToughSonic 3 is an all-purpose ultrasonic sensor with a maximum range of 3 feet (91 centimeters). This short range sensor has the same 30 millimeter stainless steel housing as the ToughSonic 14. It features a short 1.75 inch (4.5 centimeter) minimum range and a narrow ultrasonic beam width for measuring in tight spaces. And, like all ToughSonic sensors, it’s built for durability and ease of use in tough industrial environment s. It’s fully submersible, corrosion resistant, shock resistant and all around tough. It’s also fully configurable with our SenixVIEW software or with our famous Teach feature for push button configuration.","This sensor was designed for applications where the ToughSonic 14’s larger minimum range and\/or wider ultrasonic beam prevents its usage. If your application can accept the ToughSonic 14’s operating parameters, we recommend that you use it. If you need a smaller minimum range or smaller ultrasonic beam size, then the ToughSonic 3 is an excellent alternative."
