GJT Window Metal Detector

Name: GJT Window Metal Detector
Brand: COWIN MAGNET

Product role

Overview and how it fits the process

The GJT window metal detector is an inspection device installed around a defined material path. It is used to detect a metal signal under the conditions set by the actual opening size, conveyed material, product effect and line configuration. A detector is not represented as a magnetic separator or as an automatic removal device: the required alarm, stop or reject response must be specified with the conveyor line.

Selection starts with the window dimensions, the material being conveyed, expected contaminant, belt speed, product condition and required response after a signal. Where ferromagnetic contamination needs to be physically removed, a magnetic stage can be reviewed separately in the process sequence.

Selection logic

Why this configuration needs site information

01

Detection is not removal

A metal detector identifies a signal under its configured conditions. The alarm, stop or reject response is a separate line-design decision.

02

Opening and material matter

The window size, conveyed material, moisture or product effect and belt conditions should be reviewed together.

03

Integration is part of selection

The detector needs a defined conveyor or chute position, electrical interface and response procedure for the operating team.

04

Magnetic separation can be complementary

A magnetic separator may remove ferromagnetic contamination upstream, while a detector can be used for the separate detection role required by the line.

Selection checklist

What to send for an initial configuration review

Describe the actual conveyed product and operating conditions.
State whether the line requires an alarm, stop signal or a separately designed reject action.
Do not use a metal detector specification as proof that metal is automatically removed.

Important boundary

Detection capability must not be claimed without the actual material, aperture and operating condition.
The detector is not presented as an automatic metal-removal device.

Product FAQ

Questions to resolve before ordering

What does a window metal detector do?

It monitors material passing through a defined aperture and provides a response according to its configuration. The final detection capability depends on the actual product, opening and operating conditions.

Does a metal detector remove metal automatically?

Not by itself. Removal requires an appropriate reject, stop or downstream separation arrangement designed for the production line.

Can a magnetic separator and metal detector be used together?

Yes, when their separate roles are clear: magnetic equipment addresses ferromagnetic material, while a detector provides the detection function required by the line.

What is required for a detector selection review?

Provide the window size, conveyor arrangement, material, product effect, expected contaminant, belt speed, required response and available electrical interface.
