Improved Worker SafetySignifcant reduction in the need to work at height

No need to stretch across production line equipment to conduct performance monitoring tests

Emulation uses Virtual Network Computing (VNC) client technology to provide remote access to and control of the metal detector HMI via networked devices. This is ideal when they are installed in inaccessible locations, supporting increased efficiency, improved quality processes, and enhanced worker safety.

MINI Case StudyA typical snack food company with 10 production lines uses the Reduced Test Mode feature to reduce the frequency of its performance monitoring tests from 12/day to 2/day. Manual testing is still conducted once within the quarantine period.

As a result of reducing the testing frequency by 83%, the company benefits from increased production and improved operator efficiency. Worker safety is improved due to a significant reduction in the number of ladder climbs required to perform testing procedures.

A cereal producer has installed an ATS on each of its throat metal detectors. This has enabled the company to reduce the number of line operators required to perform monitoring tests by 50%, and reduced the time taken to perform each test by 90% (from 5 minutes to 30 seconds per line).

Worker safety is improved through a considerable reduction in the need to work at height and stretch across production equipment to conduct performance test procedures.

Mini Case Study

Results from using Reduced Test Mode:25 million more packs produced per year

4200 man hours saved annually

*Subject to quarantine periods and site-specific operating conditions

A typical snack food manufacturer has 24 weigher/bagger lines, running at an average speed of 100 bags per minute. The facility currently performs performance monitoring tests every 2 hours (12 times per day). Each test procedure takes 3 minutes, and results in the line stopping.

Production Impact

Testing Every 2 Hours*(current)

Testing every 12 hours*(running in Reduced Test mode)

Production timelost per day:

3 minutes x 12 times per day x 24 lines= 864 minutes

3 minutes x 2 times per day x 24 lines= 144 minutes

Product packslost per day:

144 minutes x 100 bags per minute= 14k bags

864 minutes x 100 bags per minute= 86k bags

The ATS - Auto Test System can be installed to complement manual test processes.

Process quality is improved through increased repeatability of test procedures for all available metal types.

Reduce actual test time to less than 30 seconds per line and improve test repeatability

Reduced Test mode monitors metal detector performance to ensure it is always working to or better than the required specification.

Increased confidence allows operators to reduce the frequency of testing, subject to quarantine periods.

Reduce the frequency of performance monitoring testing by up to 83%

TEST/day TEST/day

New eDriveTM technology delivers up to 20% improved spherical sensitivity.

This means significantly shorter irregular shaped metal contaminants such as sieve wire can now be detected, for improved brand protection.

Detect up to 50% smaller irregular shaped metal contaminants in high volume, dry product applications
