Roller transducers are used in testing metallic or non-metallic materials for bonding/segregation in CFRP/GRP including Kevlar®, rubber friction materials, and high density products such as glass, and metallic and plastic weldments. This series includes roller and contact type transducers at 0.5 MHz and 1.25 MHz. Contact units are available in 5, 10, and 15 mm diameters, while the roller transducers incorporate a 5 mm crystal giving a 10 mm footprint through the replaceable tire. Both styles are fitted with axial mounted Microdot connectors (other connectors available on request). The roller transducer can be ordered with either a single or dual yoke design.

Roller transducers are used in through transmission mode for fast linear scans of parts without the need for an immersion setup. Roller transducers are typically used in applications looking for de-laminations in multilayer materials and are available in either single or dual yoke designs feature a removable and replaceable tire.
聚合物 (PVDF)
Polymer (PVDF) Immersion Transducers
High frequency polymer (PVDF) transducers are focused immersion transducers with very broad bandb, whose element provides an excellent impedance match to water that results in a better transfer of sound energy. These transducers also eliminate the need for the fused silica delay lines typically found in high frequency immersion transducers, removing the echo multiples associated with delay lines. Note: Polymer transducer center frequencies are based on the film thickness of the polymer film element. Perbance is highly dependent on pulser and cable characteristics and effective center frequency may be 15 - 25% lower than the nominal value.

• Due to the fact that polymer transducers are inherently broadband, their center frequency may be lower than the frequency indicated on the transducer
高溫&低頻
Continuous High Temperature
Delay Line Transducer
This transducer can continuously withstand temperatures as high as 350°F (175°C) and pressures up to 85 PSIG. One typical application is to monitor the cure of materials in autoclave.
Part number is X2002, (2.25 MHz, 0.5 inch, 13 mm diameter)
Low Frequency Narrowband Transducers
Meant for use in pairs for through transmission in materials such as concrete, wood, and geological samples, these are available in frequencies of 50 kHz (X1021), 100 kHz (X1020), and 180 kHz (X1019). Recommended instruments are high voltage pulser-receivers such as the Model 5058PR or 5077PR Square Wave Pulser.
