MassaSonic® TR-89B Ultrasonic Transducer Proximity Sensor
The MassaSonic® TR-89B Series Transducers are rugged electro-acoustic devices designed for the efficient generation of ultrasonic energy in air. They are ideally suited for a wide variety of low power, general purpose applications, such as ultrasonic intrusion alarms, proximity detection devices, remote control devices, and energy management systems.
TR-89B Transducers consist of a one piece housing with an integral diaphragm. This provides a moisture-proof unit, suitable for both indoor
and outdoor use when mounted so that the rear terminals are protected from exposure to the direct outdoor environment. The units operate at resonance on the first harmonic overtone. This affords greater efficiency (higher transmitting and receiving response) than an equivalent size device operating at its fundamental.
