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.
