Ultrasonic Sensors Solving Distance Measurement Automation Challenges

PulStar SensorMassaSonic PulStar® Series Ultrasonic Sensors are ruggedly designed transmitting modules that provide reliable continuous level or distance measurement of fluids, pastes, or solid bulk materials.  These sensors accurately operate at application ranges from 4 inches (100mm) to 20 feet (6m).

Incorporating state-of-the-art ultrasonic technology and processing algorithms, all PulStar models provide precision non-contact distance measurement for applications such as factory automation, process control, tank level monitoring, or object detection applications.   False echoes due to structure interference are not a problem because of advanced processing algorithms. The PulStar and PulStar Plus are the next generation improvements to Massa’s Legacy M-300 and M-320 product lines, and are completely backward compatible with existing M-300/M-320 installations and software. The NEW PulStar TTL Sensors are designed for easy electronic and mechanical interface to the control system of an OEM system integrator.  These rugged Sensors are RoHS compliant, IP68 rated, and available in three versions.  Contact a Massa Applications Specialist to discuss your specific sensing needs.

Applications

Here are just a few examples of our ultrasonic sensors being used in various field applications.  The possible combinations and applications are endless with a fully customizable sensor for your needs.

Roll Diameter Measuring Sensors

Accurately measuring the various distance of a roll diameter as it unwinds can enable factory automation in such applications.

Distance Detection Sensors

Scanning and measuring distances is crucial for highly automated machines to correctly place themselves in the appropriate postion.

Stacking Level Measurement Sensors

Ultrasonic sensors can target highly accurate distances of target material enabling accurate stacking and packing automation.

Fully Customizable Distance Measurement Sensor Solutions

PulStar Standard Series Sensor

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.
