Tramp Metal Detector Oretronic III

Theory Of Operation

103

Detector de Metal

El Detector de Metal Activa un Rele de alarma ,el cual tipicamente es usado para detener la Correa y remover el Contaminante

Se usa antes de un proceso de Clasificacin con Arneros, Chancado o cualquier otro lugar donde un contaminante Metalico, puede producir un Dao

104

Principio: El campo

electromagnetico estcontinuamenteoscilando.Cuando un contaminanteconductivo pasa sobrela Bobina ,la oscilacin cambia esta es detectada porrla electrnica y unaalarma es activada.

Sistema Tipo Inductancia

105

Sistema Tipo Inductancia

Ventajas:

1. El sistema Inductivo es mas sensible que el Sistema Eddy Current.

Desventajas:

1. El Contaminante debe ser mas conductivo que el Material Transportdo.

2. Si el material es conductivo ,produce falsas paradas.

3. El Agua es un conductor y produce falsas paradas.

4. La sensibilidad variar de acuerdo a la separacin de las Bobinas

5. Minerales no conductivos como el manganeso no serandetectados.

106

Sistema Tipo Eddy Current

Principio:La Bobina Transmisora ,enva un pulso de energia.Esta energia es absorbida por el Material.

Despues que el pulso para, el material iradia la energiaabsorvida como una corriente Eddy.

El volumen de energia y su razon de decrecimiento es la firma de el material , su huella digital, siendo estemineral o contaminante. La electronica puede dicernirentre Mineral y Contaminante..

Eddy Current Type System

Advantages: Completely ignores water. Can find non-ferrous metals such as manganese. Dual coil arrangement is not sensitive to the tramp metal

location in the material burden.

112

Eddy Current Type System

Disadvantages:

Dual coil arrangement is subject to material hitting the upper coil on high tonnage applications.

The frame assembly is constructed of fiberglass and plastic to eliminate problems associated with wood

The swing arm is cantilevered to better assist the transmitter coil to swing out of the way

Spring loaded shock absorbers provide a positive cushion against shock

Ramsey Oretronic III

The coil assemblies are constructed of PVC plastic and use a potting compound to eliminate moisture problems

The single coil unit has both the transmitter and receiver coils contained in one coil assembly

Ramsey Oretronic IIIFeatures and Benefits

Ramsey Oretronic III is available in both a single and dual coil configuration. New and improved frame assembly and coil bonding procedure greatly reduce

moisture problems. Cantilevered swing arm allows easy swing-out. The Oretronic control unit has been upgraded from an 8 bit to a 16 bit

processor for greater sensitivity. All adjustments and calibration are performed from the front panel, allowing the

enclosure to remain closed. Password protection prevents unwanted entry. Adjustable frequency allows you to select an operating frequency that is not

affected by RF noise. Two or more units can be synchronized to eliminate crosstalk. RS-485 is standard with each unit. This allows Modbus communications with a

remote front panel terminal that is located outside a hazardous area.

Ramsey Oretronic IIIFeatures and Benefits

Speed pick-up input is available. This will allow the display to show the distance to the tramp in tenths of feet.

A light stack is available which has red, green and amber lights stacked one on top of another to indicate control status.

All other options previously available are still offered. Clip Detector High Pile Detector Custom Contoured Coils Spray Marker System Mechanical Flag Drop Alarm Horn Rotating Beacon Light Stack (New)
