An existing industrial sensor is used to monitor the production of synthetic polymer fiber, by measuring changes as fiber passes through an electromagnetic field. Dedicated analog circuitry performs low-level processing to detect specific physical structures in the fiber. Measurement of a given fiber requires fine-tuning of the analog circuitry, so the sensor cannot be configured to optimally measure multiple fiber types.
It is proposed that the analog circuitry be replaced by a digital equivalent, using digital signal processing techniques where applicable. This will facilitate a less complex calibration procedure and allow real-time sensor parameterization. Effectiveness will be evaluated against the existing analog sensor, in terms of speed, accuracy, cost, and power consumption.
