Series 4B-QDF Metal Detector

The QDF is a high performance Metal Detector suitable for detecting ferrous and Nor-ferrous metallic contamination in a wide rang of food or other products. The QDF consists of an Aluminum constructed detecting head with full surround triple coil system filled with a Non-shrink Urethane resin for complete sealing. The system operates using analogue main controls with digital plus phase modulation and phase discriminating signal demodulation network coupled to a dual gated signal detection system for maximum performance.

The system is designed with full automatic temperature control with AFT & AGC/AFC circuits for maximum performance on conductive products. Full reject timer facilities are also provided with the system including output relay for controlling external equipment.
The unit can also be constructed with remote mounted controls up to 15 meters away from the detector head without any operating problems.
