Single Element Delay Line Pencil Transducers

Dakota's pencil transducers can be used in conjunction with the TI-PVX Ultrasonic Thickness Gauge and can be applied for the testing of aluminum, titanium, steels and thin plastics.

Pencil probes concentrate the sound beam to a 1/16” spot which is best for measurements on containers, small diameter tubes, turbine blades, etc. Using a high impedance couplant makes coupling easier. Care must be exercised to place the probe perpendicular (90°) to the test surface.

The pencil transducers are available in three different models:

T-481-5507: 3/16" Diameter, 10 MHz, 1/16" Tip with Top Entry and Microdot Connector
T-681-4507: 3/16" Diameter, 10 MHz, 90° Right Angle with Side Entry and Microdot Connector
T-581-5507: 3/16" Diameter, 15 MHz, 1/16" Tip with Side Entry and Microdot Connector

Acrylic delay tips will measure plastics if the material velocity is different from that of acrylic. If the velocities are similar, a graphite tip will need to be used. Measurement ranges in plastics will vary depending on the type of plastic measured. Delay tips X-152-0000 and X-752-0000 are applicable when using the pencil transducers. The measurement ranges will be specified in the table below.

Ranges were determined using standard 4340 steel calibration standards, and common plastic samples. These ranges may vary according to material type differences and surface conditions.
