Electroacoustics, Ultrasonics, and Sonar Sensor Manufacturing for Air and Fluid Applications
For over 80 years and counting, Massa has set the standard in the electro-acoustic industry by offering a wide variety of sensing solutions for various applications. We offer standard, OEM, and customized configurations to meet our customers’ specific needs and use-cases.
Ultrasonic Sensors
Massa specializes in designing and manufacturing the highest quality level sensors ideal for non-contact distance measurement in the harshest environments. Massa produces several different series of level sensors and monitoring transmitter modules that provide reliable continuous level or distance measurements of fluids, pastes, solid bulk materials, or mechanical structures for application ranges from 1 inch (25 mm) to 20 feet (6 m). For more information about sensor manufacturing, please visit our Ultrasonic sensors page.
Ultrasonic Air Transducers
Massa has developed many different ultrasonic transducer designs for an extremely wide range of applications for use in air. We created the first standard microphones for accurately measuring sound fields in the ultrasonic range and the first standard accelometers to measure vibrations and shock pulses at frequencies up to 100 kHz. Hundreds of different transducers have been designed that operate at different frequency ranges of 20-500 kHz, and millions of transducers have been manufactured.
