Continuous Non-Contact Distance measurement for any application

Pulstar 150 Sensor - Massa

MassaSonic PulStar® Series Ultrasonic Sensors are ruggedly designed transmitting modules, providing reliable continuous level or distance measurement at ranges from 4 inches (100mm) to 20 feet (6m). The PulStar® series products are a direct result of improvements made upon the M-300 and M-320 sensors and serve as a drop-in replacement for those legacy products. These durable Sensors are RoHS compliant, IP68 rated, and available in three versions. All models provide precision measurement for applications such as factory automation, process control, tank level monitoring, object detection, and more. With the inclusion of state-of-the-art processing algorithms, false echoes due to object interference are a thing of the past.

Pulstar 150 Sensor - Massa

The lower cost standard models in the PulStar Series are accurate, rugged, and particularly ideal if false echoes from sound reflecting structures between the sensor and the surface being measured are not encountered and extended detection ranges not required.
