Low-frequency ultrasonic transducer S3740

piezoelectriclongitudinal wave

Low-frequency ultrasonic transducer for transmitting and receiving the longitudinal ultrasonic waves A general-purpose ultrasonic transducer S3740 can be applied for ultrasonic testing of various materials and products to detect material flaws using transmitting and receiving ultrasonic longitudinal waves. The transducer can be used as a part of ultrasonic low frequency flaw detectors in pulse-echo mode or ultrasonic pulse velocity testers in through-transmission mode. The transducer can be driven by following ACS instruments: • A1220 MONOLITH Type of transducer - Piezoelectric, single crystal Type of generated wave mode - Longitudinal Nominal frequency - 250 kHz Effective aperture - 30 mm Delay time in transducer protector - 0.1 ms Piezo-element electric capacity - 12600 ± 2500 pF Maximum excitation pulse voltage, V - ± 200 V Operating temperature range - –20...+50°C Connector type - LEMO00.250 Overall dimensions - 36.5 х d40 mm Weight - 220 g
