Model PL – Flat Belt Conveyors
For flat belt conveyor applications, Eriez recommends a Model PL MetAlarm. The Model PL is supplied with 6600, 3500 or 3500/QM2 Control.
The unit is easy to install and the Model PL is especially effective for picking up metal contaminants where the search coil is surrounded by metal conveyor frames or moving metal like mobile crusher applications.
Model PL2 – Plastics Industry
Eriez’ Model PL2 MetAlarm Metal detector has been specifically developed for direct attachment to lightweight conveyors used to feed granulators with tops and tails, sprues, etc., from molding machines of all types. It will prevent the majority of small metal pieces of all types from entering granulators, damaging blades and contaminating the granules produces.
Model VC – Vibratory Conveyors
The Eriez MetAlarm Model VC Metal Detector offers an all-in-one unit including search coil and metal-free section. It is supplied with a Model 3500 control connected to the search coil that is integrated into the tray’s trough section. When metal is detected, the conveyor and material flow is stopped to allow manual removal of the metal. Audible and visual alarms are available as optional extras.
Model TR – Troughed Conveyors
For use with angled trough conveyors. Eriez’ Model TR MetAlarm is ideal for detecting large tramp metal. The Model TR is used in a variety of different industries such as wood, plastics, aggregate and mining. The Metalarm’s lightweight design proves easy maneuverability and quick installation. In most cases, it can be installed with little or no adjustment to idler spacing. Units can be supplied for belt widths from 20 inches (500 mm) up to 80 inches (2000 mm).
Model BR – Troughed Conveyors
Similar to the Model TR MetAlarm, the Model BR MetAlarm (bridge design) is excellent for detecting tramp metal in burden depths greater than 14 inches (356 mm).
The The transmitter/receiver coil combination is excellent for mineralized materials and also for use when nothing smaller than a certain size metal should be detected. This removes the risk of “nuisance trips” for small metal that will not damage machinery, thereby reducing costly downtime.
Its lightweight design makes it cost efficient to install on most trough belt conveyors.
Metalarm HH-10 Handheld
Eriez’ MetAlarm Model HH-10 Handheld Metal Detector is designed to locate the exact position of small pieces of unwanted tramp metal. The detector activates audio and visual alarms whenever metal is present.
This durable, lightweight and sensitive device can be used in a variety of industries that currently employ an existing in-line metal detector. The HH-10 should be used after a detection has occurred and the product flow has stopped.
For example, when used in the aggregate industry, the HH-10 will scan shallow burdens on non-metallic surfaces, detect tramp metal and allow for quick recovery.
The HH-10 is also ideal for use in companies that manufacture thin, webbed products such as textiles, garment, particle board and pulp and paper products. This highly sensitive instrument will detect minute pieces of meal as small as 1mm.
No batteries required! The plug-in-and-go design ensures consistent voltages, which optimizes sensitivities unlike batter-operated unites which lose sensitivity.
Metalarm Control Units
Eriez MetAlarm control units employ ‘Pulse Induction’ technology circuitry, which has a proven track record of being reliable and rugged in tough conditions.
The MetAlarm controls are available in both mild steel painted (known as MA) and stainless steel (known as Quarrymaster or QM) versions. The QM models are also fitted with heater modules for use in cold conditions and have an optional belt clip detection facility for installations where belts have been repaired with metal clips.
Both MA and QM models are also available in Hi Power versions that offer enhanced detection sensitivity whilst still maintaining ease of use and minimal on-site adjustments. These features ensure that all Eriez MetAlarm detectors are extremely practical for users in any industrial environment.
