Fiber Optic Sensor Pre-settings

The pre-setting function allows fiber optic sensors to establish reference values and optimize sensitivity for accurate detection under varying conditions.

Overview of Pre-setting Function

The pre-setting function in fiber optic sensors is designed to calibrate the sensor to a reference condition, ensuring reliable detection even when environmental factors like dust, dirt, or light intensity fluctuations are present. This function can be used to set the sensor's current value to a baseline (0. 0) and a slightly higher reference (100.

0), which is particularly useful for reflective models or when using the background as a reference.

How It Works

Manual Initialization: Press and hold the and buttons simultaneously for three seconds. Select "rSt" and then "init" to initialize the sensor. After initialization, the display returns to the current value.

Automatic Sensitivity Adjustment: The sensor can automatically adjust sensitivity while a workpiece passes through, allowing calibration without stopping line operations. Reference Value Setting: The pre-setting function allows the current value to be corrected to 0. 0, and an arbitrary second point can be set to 100.

0. This two-point calibration reduces variation in detected contents and accounts for individual sensor differences. Disabling the Function: Press and hold to disable the pre-setting function.

Note that it cannot be used simultaneously with the zero-shift function.

Practical Benefits

Compensation for Environmental Changes: Adjusts for decreased light intensity due to dust or dirt, maintaining detection accuracy. Predictive Maintenance: By standardizing reference values, the sensor can help predict when maintenance is needed. Operational Efficiency: Enables calibration during ongoing operations without stopping production lines.

Enhanced Detection Accuracy: Reduces variation caused by individual sensor differences or inconsistent workpiece positioning.

Applications

The pre-setting function is widely used in industrial automation, assembly lines, and quality control systems, where precise detection of objects or materials is critical. It ensures that fiber optic sensors maintain consistent performance in environments with variable lighting or reflective surfaces. In summary, the pre-setting function is a key feature for optimizing fiber optic sensor performance, providing both manual and automatic calibration options to maintain accuracy, reduce variability, and support continuous operation.
