The Series HZD-RMC high performance metal detectors are suitable for detecting ferrous and non-ferrous metallic contamination in a wide range of non-metallic products in a hazardous areas. These units consists of an inspection head, with optional remote mounted Controls fitted with a signal strength LED display module, Power Supply and Relay mechanism. The product to be examined falls through the aperture via a non-metallic tube, or conveying system etc. A penetrating electromagnetic field is generated within the aperture, and metal; no matter how deeply embedded in the product, it can be detected. The TRIP relay contacts may be used to actuate a visual or audible alarm, stop conveyor motors or actuate automatic reject mechanisms etc.
The metal detector head is fitted with an FJB211 certified enclosure & glands housing the electronic controls, and powered by a low voltage 20v AC passed through a rectifier/regulator & filter system, to provide clean DC power to the detector head operating components.
Mains power passes through a Toroidal Transformer via Dual safety fuses to provide low safe working voltages to the complete system.
