Abstract
The need for miniaturised sensors in a production environment is rising due to the pressure for on-line quality control. Efficient monitoring of the production process reduces raw material waste, increases productivity and lowers operating costs. Currently, mechanical contact sensors and magneto/electro non-contact sensors are employed. Optoelectronic sensors can provide an attractive alternative, as the optical signal probe is non-contacting, is immune to electric and magnetic fields, and can deliver a more accurate measurement. However, in order for optical sensors to be a viable alternative, accuracy and cost effectiveness is an issue, especially as compared to the savings obtained as a result of the increased accuracy.
