Loop Control of Clear Plastic
The detection of clear plastic is always a challenge. The optical beam of traditional photoelectric sensors will burn through clear material, making sensing results unreliable.
The U-GAGE T30UX Series Ultrasonic Sensor uses pulses of ultrasonic energy, which reflect off the target and back to the sensor, to reliably detect clear materials. In this application, a T30UX with an analog output is being used to monitor the tension of the loop. By sending a continuous analog signal to a PLC, the sensor will communicate when the loop lowers or rises, indicating that the rollers need to speed up or slow down.
