Ultrasonic Contact Transducers

Ultrasonic Transducer for Flaw Detection, Thickness Gauging and Fluid Level Gauging

Ultrasonic Contact Transducers for flaw detection, thickness gauging and fluid level gauging.Piezo Technologies' Ultrasonic Contact Transducers are designed for general purpose flaw detection and thickness gauging of metals, plastics, ceramics, elastomers, and composites. Contact NDT transducers can also be used for fluid level gauging from outside the tank.

Piezo Technologies' Ultrasonic Contact Transducers are available in longitudinal and normal incident shear; and low, medium, and high damping for most models. A NDT contact transducer is normally supplied with a wearface, but when specified, Piezo Technologies will acoustically optimize contact transducers for their intended application.

Contact transducers are compatible with most commercial flaw detectors and thickness gauges. A Piezo Technologies ultrasonic contact transducer is available with axial or right angle BNC, Microdot, Lemo, UHF, or TNC connectors or potted cable. Housings are stainless steel. Other frequencies and sizes that are not listed in the table may also be available.

Piezo Technologies develops and manufactures semi-custom, modular, and pure custom (no off-the-shelf) ultrasonic transducer products. Our vast database of past projects provides a base for developing many new products as semi-custom or modular devices. This reduces both cost and turnaround time, while still providing a high quality, unique product. We also specialize in developing pure custom devices. Our technical experts are available to discuss your application and recommend an ultrasonic transducer product that will satisfy your specific requirements.
