The QDF is a high performance Metal Detector suitable for detecting
ferrous and non-ferrous metallic contamination in a wide range of food or
The QDF consists of an Aluminum constructed detecting head with full
surround triple coil system filled with a non-shrink urethane resin for
The system operates using analog main controls with digital pulse phase
modulation and phase discriminating signal demodulation 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 20
meters away from the detector head, or with flanges for special
