At Massa they enjoy recognized leadership in reliable electroacoustic products for underwater applications and have pioneered many state-of-the-art advances in sonar technology during the last 50 years.

Massa achievements have included ultra-precision hydrophones…the world's largest underwater sound sources generating millions of watts of acoustic power…and many of the sonar transducers presently used by navies of the U.S. and free world nations, including the TR-208A/SQS-23, TR-237, TR-238, and the TR-330/SQS-56 Transducer Arrays.

Massa Products Corporation has been producing ultrasonic transducers that operate in air for industrial applications for over fifty years. They have designed hundreds of different types of transducers having a wide variety of electroacoustic characteristics for use in many applications, including liquid and bulk level detection, counting, position location, profiling, collision avoidance, web break detection and tensioning, ultrasonic intrusion alarms, and an automatic scoring system for ten-pin bowling.  Some of these transducers have been mass produced at a rate of 40,000 per week.

If you know the type of transducer you require with regard to such characteristics as frequency of operation, radiation beam pattern, housing material, open or closed construction, bandwidth, impedance and size Massa has included data sheets on their transducers through their web site. If you are unsure as to which transducers you need, or if you have a specialized OEM application, please contact them.  Many of the transducers and systems that they supply to their OEM customers have been customized for each requirement.
