How Can Senix Non-Contact Ultrasonic Sensors Measure & Control Roll Diameter?

Senix ToughSonic General Purpose ultrasonic distance and levels sensors are designed for use in some of the harshest industrial environments and are suitable for use with a variety of materials, ranging in type, color, translucence, and reflectivity, from aluminum to steel and paper to plastic.  Unlike other techniques such as optical or photoelectric sensors, Ultrasonic […]


How Do Ultrasonic Sensors Work?

Ultrasonics refers to signals that are above the human hearing span (>20 kHz).  There are several types of Ultrasonic transducers. Industrial Ultrasonic sensors that measure through air generally transmit between 30 KHz and 500 KHz. As the ultrasonic frequency increases, the rate of attenuation increases. Thus, low-frequency sensors (30–80 kHz) are more effective for long […]


Ultrasonic Sensor Selection Guide

Ultrasonic sensors are engineered to measure the distance to a remote object through the air without physically touching it. They determine this value by emitting high-frequency (ultrasonic) soundwaves toward the object being measured, receiving the reflected wave, and calculating the time between emission and reception. Due to their unique operational characteristics, these distance measurement sensors […]
