The Series 4B also offers an excellent choice of unit size depending on the particular application. The product can be passed through the aperture via conveyor belt, inclined chute, or non-metallic pipe. Each model in the range operates with a Digital Pulse Phase Modulation and Phase Discrimination Signal Demodulation Network coupled to a Dual Gated detection system.

This system aloows Product Compensation and minimises the amount of good
product reject. The detector can be adapted to high or low conveyor speeds, and features Fault Monitoring which helps reduce errors to an absolute minimum.

Ultimately, it is the sensitivity of the Detec Series 4B that puts it in a high performance class.
