New ultrasonic transducers and transceivers support high volume applications

New Products |
By eeNews Europe

The high quality components are suitable for use in a wide range of applications and environments, including externally, underwater and in dusty, contaminated conditions. The products include aluminum housed open type transducers available at various diameters and centre frequencies, from 25 to 40 kHz, featuring piezoelectric ceramic discs mounted at the point of their resonant frequency. The free vibrating nature of the open type design makes these transducers ideal for applications involving continual wave driving, such as Doppler motion detectors, remote control devices, robotics, security alarms and energy saving requirements.

The closed versions consist of an aluminum housing with an integral diaphragm, with the transducers resonating at the first harmonic. Their completely sealed resin housings mean that these transducers are ideal for outdoor use, and have applications as components in paper feeding detectors, presence detectors, counting device and flow measurement sensors.

The range also includes 40 kHz open pulse ultrasonic transceivers with ceramic resonators, available in both aluminum and plastic housings which require a shorter ringing characteristic compared to standard type transducers.  One of the key products in the new ProWave range is an underwater ultrasonic transceiver, which features a submerged impedance of 200 Ω, capacitance of 2000 pF and a receiving sensitivity of – 180 dB.
