Single Element Delay Line Pencil Transducers

Made in the USADakota'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.
