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 sensors measure roll diameter regardless of the roll material type, color, or hardness and provide fast, accurate and reliable diameter measurements whenever the target is within range. With their high reliability, these easy-to-use sensors are an excellent solution for many roll measurement applications.

Roll Diameter Measurement

Senix ToughSonic® ultrasonic sensors use “non-contact” technology to measure the roll diameter of materials without touching or damaging the target as they are wound and unwound for various applications.

Roll Full Detection

Roll full detection is used to measure the diameters of rolls as material winds onto them. When a roll is full, the sensor sends a notification to the system and any other connected devices, so the necessary equipment or employees know to remove it.

Roll Empty Detection

Roll empty detection is used to measure the diameters of rolls as material winds off them. When a roll is empty, the sensor sends a notification to the system and any other connected devices, so the necessary equipment or employees know to replace it.

Roll Slack Monitoring (or Tension Control)

Roll slack monitoring is used to monitor rolls as material winds onto them or off them. If the amount of slack in the material exceeds a set limit, the sensor sends a notification to the system and any other connected devices, so the necessary equipment or employees know to tighten or loosen the material.

Senix ToughSonic sensors have a variety of outputs. Senix Sensors include both 0-10 VDC and 4-20 mA analog outputs, and choice of RS-232 or RS-485 serial communication, and built-in switches to signal motor drives, brakes, clutches, or controllers to manage web motion in production. ToughSonic sensors include synchronization features to prevent crosstalk from multiple sensors in close proximity.
