Seamless 'Detect and Reject' of Contaminated Products
Our Gravity Fall metal detector systems are designed to inspect bulk, free falling fine powdered and granular products in food production and non-food applications. High volume products are able to free-fall, or drop through a small metal detector aperture delivering very high sensitivity. The combination of maximum detection capability, efficient rejection systems and new technology to optimize performance testing leads to increased operational efficiency, maximized profitability, and easier compliance with both industry standards and regulations.
Unlock Productivity Performance
To minimize the risk of product recalls in food production due to metal contamination, the latest Profile Gravity Fall metal detector systems are equipped with eDrive™ technology. eDrive™ delivers enhanced sensitivity to all metal types, including ferrous, non-ferrous and difficult to detect grades of stainless steel, enabling smaller irregular shaped metal contaminants to be detected. Reduced Test mode can significantly reduce the frequency of performance testing, increasing production capacity.
Reduce Total Cost of Ownership
To stay competitive, it is essential to reduce manufacturing costs. Installing the latest METTLER TOLEDO Safeline Profile Gravity Fall metal detector can lower the total cost of ownership through optimized performance testing processes and seamless integration with other inline processing equipment. Emulation technology improves operator efficiency and supports enhanced quality processes to help manufacturers comply with industry standards and regulations.
Bespoke Systems to Suit your Application
Safeline Gravity Fall metal detector systems are designed with a range of high-speed reject devices to remove metal contaminated products from the production process. Choose from a Y-Valve system for powders and granular products, a Sealtite system for high value and dusty powders or an Open Diverter system for non-dusty products. Reduced height systems are available for applications where installation space is limited within the production line. If operating in a potentially explosive atmosphere, certain Gravity Fall metal detection systems can be supplied to comply with ATEX/IECEx regulations.

FAQ
How do Gravity Fall metal detector systems work?
Gravity Fall metal detector systems are suitable for the inspection of any free-flowing powder or granular products such as flour, milk powder, dried fruits and peanuts. The product flows through the production line and free-falls under gravity through a small metal detector aperture, achieving high sensitivity. On detection of metal, a fully automatic, high-speed reject device diverts the contaminated product, isolating it from the main product flow.
How do I choose the most suitable Gravity Fall metal detector system?
Gravity fall metal detection systems are designed specifically for the inspection of free-falling powders and granular products in non-pressurized applications and different reject devices depending on the inspected application. Y-Valve Gravity Fall systems are suitable for the inspection of powders and granular products. The Y-Valve's quick release and captive reject mechanism simplifies cleaning procedures, ideal when product changeovers are frequent and when regular cleaning between production batches is required.
Sealtite Gravity Fall systems feature an innovative design to provide a dust-tight seal. This virtually eliminates the escape of un-contaminated product into the reject channel, reducing product waste. Sealtite technology is ideal for inspection of high value, dusty products in explosive environments and applications where insertion space is limited.
Open Diverter Gravity Fall systems provide a cost effective solution for non-dusty products, and can be upgraded to Sealtite standards retrospectively if required. This system is best for non-dusty granular products where insertion space is limited.
How can a Gravity Fall metal detector system boost productivity?
METTLER TOLEDO Safeline's Profile technology allows manufacturers to reduce the frequency of routine performance monitoring tests through Reduced Test Mode and decrease the time taken to conduct performance monitoring tests through its Automatic Test System (ATS) – boosting productivity on the production line
Reduced Test Mode monitors the metal detector's performance to a level of certainty that the frequency of routine performance monitoring can be significantly reduced, subject to quarantine periods.
ATS decreases the time taken to conduct performance monitoring tests by >80% (from 3-5 minutes per line, to under 30 seconds per line).
In some cases, depending on the testing protocol undertaken by your business, Reduced Test Mode and ATS can lead to significant uptime advantages, improved overall equipment effectiveness (OEE) and cost savings – all highly desirable attributes in today’s demanding production environments.

Does METTLER TOLEDO Safeline supply Gravity Fall metal detectors that are ATEX/IECEx compliant for explosive atmospheres?
If operating in a potentially explosive atmosphere, certain Gravity Fall metal detection systems can be supplied to comply with ATEX/IECEx regulations. Please discuss your requirements with your local sales representative.
How can a Gravity Fall metal detector enhance worker safety?
METTLER TOLEDO Safeline Profile Gravity Fall metal detectors can contribute to safer working practices in food manufacturing environments.
By reducing the frequency of metal detector testing using new Reduced Test Mode technology, there is a corresponding reduction in the number of ladder climbs required by an operator to conduct the test, either to drop the sample through the aperture, or to access the HMI to run the test routines.
Emulation, another feature available on our Profile metal detectors, allows the metal detector HMI to be controlled from a variety of networked devices such as a tablet or mobile phone, again reducing the need to work at height if the HMI is installed in an awkward location, as is the case in many dry product inspection applications.
ATS virtually eliminates the need to work at height to conduct most routine performance monitoring tests, and removes the requirement for line operators to reach across installed equipment to drop the test samples through the aperture of the metal detector.
