Shear wave ultrasonic transducer M2502

direct-contactcontactlow-frequency

Low-frequency dual ultrasonic transducer array for pulse-echo ultrasonic testing of concrete structures by means of shear-horizontal ultrasonic waves. A general-purpose low-frequency ultrasonic transducer array with the nominal frequency of 50 KHz for the dry-point-contact (DPC) pulse-echo transmitting and receiving ultrasonic waves in highly scattering materials (concrete, wood, stones etc.) by means of dual-aperture arrangement. Two independent groups of 3 x 4 elements perform transmitting and receiving of shear-horizontal ultrasonic waves and allow deep penetration and reduced dead zone of ultrasonic testing. The transducer can be driven by following ACS instruments: • A1560 Sonic-LF • A1220 MONOLITH Transducer type - Dry Point Contact transducer array Generated wave - mode Shear-horizontal Nominal frequency - 50 KHz Band width - 10 to 100 KHz Capacity - 3.500 pF ± 100 pF Maximal pulse voltage (bipolar) - 400 V (peak-to-peak) Connector type - Lemo00 Temperature range - -20 to +50ºC Dimensions - 139,5 х 105,5 х 83,5 mm Weight - 1.1 kg
