Industrial Applications

1. Liquid Level Monitoring in Small Tanks

Continuously monitors the fluid level inside small tanks or reservoirs used in bottling or chemical processing applications.

Problem Solved

Traditional floats can jam or corrode. The ultrasonic time-of-flight technology measures liquid levels accurately without contact, providing a scalable 4-20mA signal direct to the PLC.

2. Web Tension and Loop Control

Measures the slack loop of materials such as paper, wire, or film continuously to adjust the unwinding or rewinding motor speed.

Problem Solved

Ensures that the material loop remains within the ideal 30-300mm range to prevent web tearing or excessive slack, utilizing the fast 2.5 ms response time for rapid dynamic adjustments.

3. Roll Diameter Measurement

Measures the decreasing diameter of a supply roll or increasing diameter of a take-up roll on a machine.

Problem Solved

Provides continuous real-time roll size feedback independent of material color or optical reflectivity, allowing the machine drive to dynamically adjust mechanical tension as the roll changes size.
