How to Test Pipeline Metal Detection System
How to test a gravity feed metal detection system for powder and bulk product
Testing Procedure For Pipeline Metal Detectors
When using an in line metal detection system you should consider how the system will be tested. There are two basic methods for testing the model 426 pipeline system.
In line insertion
This method is the only way to confirm that the whole system is functioning correctly. During a test procedure you would insert a metal contaminate into the product flow. A second valve after the metal detection system should be installed to capture the test product in a holding vessel. If all works correctly you would divert the metal contaminate into the reject bin. If for any reason the system fails you will be able to recover the metal sample in the holding vessel.
Metal Detector Test
To determine that the system is detecting metal and operating the reject device, you can pass a metal sample between the product tube and the search head. This method however, does not confirm that metal within the product would be rejected correctly. Method 1 should be the primary testing procedure.
Optional Equipment Found On Most Metal Detectors
Reject Confirm
Most metal detectors are capable of automatically sounding an alarm if the reject device fails to operate or operates too slow.
High Temperature Or Pressure
Teflon pipe coated with F.R.P. for high temperature or pressure applications
Reporting Software
A PC software package which would monitor all critical parameters of each metal detector on-line
Automatically generates data for reports
Pipeline Metal Detection System
Pipeline metal detection systems have been developed to inspect products such as meat slurries, jams, sauces, and dairy products. Most systems are USDA approved for federally inspected meat and poultry applications.
Design Considerations
P roduct flow rate.
Increased flow rates increase the distance between the search head and the valve
Product temperature.
Typically nylon 66 pipes are standard on most systems and are rated for temperatures upto 160° F. Teflon pipes can be used for greater temperatures.
Product pressure.
Typically nylon 66 pipes are standard on most systems and are rated for upto 80 P.S.I. Teflon pipes can be used for greater pressures.
