Measure & Control Roll Diameter with Senix Non-Contact Sensors

Senix's general-purpose ToughSonic® ultrasonic level and distance sensors are designed for use in some of the harshest industrial environments. They 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 used by optical or photoelectric sensors, ultrasonic sensors measure roll diameter regardless of the roll material type, color, or hardness—they simply 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

ToughSonic ultrasonic sensors use non-contact technology to measure the roll diameter of materials without touching or damaging the target as it is wound and unwound for various applications.

Roll Full Detection

This practice measures 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

Diameters of rolls are measured 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.

Industries Served

ToughSonics serve converting, foil and film, metals, printing, and pulp and paper industries with quality, precise measurements.

Senix ToughSonic sensors have a variety of outputs, including both 0-10 VDC and 4-20 mA analog outputs, a 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 also include synchronization features to prevent crosstalk from multiple sensors in close proximity.

In addition to roll diameter measurement, learn more about other distance ranging applications such as:
