Piezoelectric ultrasonic transducer HCTG500KA

beammeasurement

Product Overview
The HCTG500KA ultrasonic transducer is engineered for integration into ultrasonic gas flow meter systems. It provides a nominal center resonant frequency of 500 kHz (±4%) and a narrow beam suitable for accurate transit-time measurements in gas applications. The element requires appropriate signal conditioning and processing when incorporated into sensor electronics.
