A web guide sensor is a crucial component of web guiding systems used in industries dealing with continuous materials like paper, film, or textiles. Its primary function is to detect and monitor the position of the material, known as the “web,” as it moves through various stages of the production process.

These sensors come in various forms, including ultrasonic sensors, photoelectric sensors, or edge sensors, depending on the specific application requirements. They are typically installed inline within the machinery handling the material and are strategically positioned to detect deviations in the web’s position relative to a predetermined path or reference point.

Web guide sensors provide real-time feedback to a web guide controller, which analyzes the data and issues commands to actuators to make necessary adjustments to guiding elements such as rollers, guides, or edge sensors. This continuous monitoring and adjustment ensure that the web remains aligned and centered throughout the production process.
