Abstract
An ultrasonic transducer having a unique design that can withstand changes in temperature and pressure and will operate in corrosive environments. The transducer is used to detect the distance to an object being measured. The device includes a diaphragm capsule from which is emitted a focused ultrasonic wave. The diaphragm capsule is machined from a single piece of metal and does not use adhesives or welded joints. The capsule is also filled with silicone oil and provided with a flexible annular ridge, both of which enhance its operation and improve signal transfer.
