Pitch-Catch Ultrasonic Transducer
An ultrasonic probe with separate transducers to optimize near-field testing.
Physical-Chemical Mechanism of Action
A transmit-receive ultrasonic probe uses separate transducer systems for transmitting and receiving ultrasonic waves. This allows more precise control of sound direction and amplitude, which increases the resolution and accuracy of the inspection.
Metallurgical Relevance & Risks in Welding
Using a transmit-receive probe minimizes noise and improves the detection rate of flaws or inhomogeneities in the material. Without this special setup, inaccurate results can occur, posing risks to safety and component life.
Workshop Practice & Instructions
Use the transmit-receive probe for near-field inspections. Ensure the transducer systems are correctly calibrated and the ultrasonic wave direction is optimally set. Precise adjustment of frequency (typically 5 MHz) and the distance between transmitter and receiver (approx. 1 cm) is crucial for reliable inspection.
