known as sandwich or trumpet type transducer, commonly known as
“planar transducer” as shown in Figure 2.2) is a kind of simple
radiator utilizing thickness vibration of piezoelectric ceramics. Planar
transducer, with interchangeable radiation and receiving functions, is
used to test concrete strength and internal defect, etc.
Planar transducer is optional part. User needs two planar
transducers and signal wire for testing strength or defect of concrete
structural members.
2.1.2.2 Radial transducer
Radial transducer, also known as tubular transducer, as a kind of
columnar transducer with good symmetric properties, is particularly
suitable for penetration test of cross-hole sound wave. Radius
transducer is the sensor for transmitting and receiving ultrasonic as
shown in Figure 2.3. All special transducers with same and
interchangeable ports for multichannel pile integrity tester may be
used for transmitting and receiving. According to different number of
channels, radial transducers in different numbers may be equipped.
The length of transducer signal wire depends on the length of
foundation pile to be tested. The radial transducer for ultrasonic pile
integrity tester is special transducer which cannot be matched with or
connected to other ultrasonic instrument.
