Sentinel 5000 Multiscan

The Thermo Scientific™ Sentinel™ family of metal detectors provide high sensitivity detection performance to increase the probability of finding ferrous, non-ferrous, and stainless steel metal contaminants in food, beverage and other products. Utilizing innovative technologies such as Multiscan™ and Selectscan™, Sentinel metal detectors help manufacturers increase customer safety, improve product quality and drive production efficiency. Discover how the Sentinel product family can meet your application needs.

Sentinel 5000 Multiscan Metal Detector

The Sentinel 5000 model is the first multiscan metal detection platform to scan a combination of up to five user-selectable frequencies to find all random sizes, shapes and types of metal foreign objects. Sentinel 5000 identifies contaminants that are up to 50% smaller in volume than the Thermo Scientific™ APEX 500 metal detector, and has the same dimensions and conveyor mounting for easy upgrade. The Sentinel 5000 can be used in a metal detection-checkweighing combination system, but due to its size must be mounted on a standalone infeed conveyor.

Sentinel 3000 Multiscan Metal Detector

Choose the more compact Sentinel 3000 model for metal detection-checkweighing combination systems. Sentinel 3000 can be integrated into Thermo Scientific™ VersaWeigh™ and Versa GP checkweigher, reducing the total footprint while combining important functions like program changes, alarms and rejection statistics. Sentinel 3000 detects contaminants up to 35% smaller in volume than the Thermo Scientific™ APEX 300.

Sentinel 1000 Selectscan Metal Detector

Selectscan technology enables food processors to have an easy way to rapidly identify the single best frequency for an application. It tunes out product effect and adapts results to account for temperature changes and electromagnetic interference. At the same time it provides documentation of results from each production run. It is a completely new and holistic approach.

All models offer the following features to achieve the highest level of food safety:

Remote control panel mounting available
Frequency Range 50 to 1000 kHz, multiscan runs up to five frequencies
Easy-to-use touchscreen with new Autolearn function to quickly optimize set-up
Detailed graphical displays for phase, rejects, quality test, and detection thresholds to enable easy fine tuning and troubleshooting
IP69K for severe washdown and dust, eliminating repair costs
All electronics are integral, so mounting is easy and flexible
All balance functions are implemented in software, so no need for manual, hardware rebalance in the field
Wide ambient temperature range assuring reliability
Fe, non-Fe and 316 SS test pieces included to fit specific application
In combos the user interface is available on the metal detector AND the checkweigher screens

Frequently asked questions (FAQs)

What is the best food inspection technology to reduce the escape rate with metal detection?

Every detection system has a probability of an escape.The type of metal, its shape, position, product effect, etc., all are factors in detecting a metal contaminant. Multiscan technology (https://www.thermofisher.com/order/catalog/product/SENTINEL5000?SID=srch-srp-SENTINEL5000) provides unmatched sensitivity and the highest probability of finding ferrous, non-ferrous, and stainless steel metal contaminants in challenging applications such as dairy, meat, poultry, bread, and other applications with high product effect. Multiscan technology reduces the number of escapes significantly, because it's like having five metal detectors back to back running the same package at different frequencies.

Are there environmental factors that can interfere with finding metal contaminants using Multiscan food metal detectors?

Small metal foreign objects have very small signals, and the food metal detector is operating in a factory that has many possible noise sources that can confuse the metal detector electronics and software. Make sure you address some of these sources that can interfere with your testing:

- Large motors turning on and off
- Electronics boxes broadcasting wide spectrums of radiated noise
- Production equipment vibrating and causing the antenna in the metal detector to move ever so slightly
- Electrical power surging and dropping
- Temperatures going from freezing to boiling and back again

Can Multiscan technology reduce the escape rate?

Every detection system has a probability of an escape. The type of metal, its shape, position, product effect, etc., all are factors in detecting a metal contaminant. Assume that in the past, you have found that 1 out of 1 million packs (1 ppm) incurs an escape. At the rate of a pack/second, 16 hours a day, 5 days a week, that is an escape about every 3-4 weeks. That escape could cost thousands to millions of dollars. Multiscan technology reduces that number significantly, because it's like having five metal detectors back to back running the same package at different frequencies.

What is the easiest metal to detect with Multiscan food metal detectors?

It is widely understood that ferrous metals are the easiest to detect due to their magnetic properties. An electromagnetic field reacts most to ferrous metal, and the lower the frequency, the greater the reaction. Conversely, stainless steel, which contains only a small amount of ferrous metal, has little or no magnetic property. Metal detectors must run at a high frequency to find stainless steel because the high frequency field induces a current in the stainless steel which creates a new field that interacts with the original field in the metal detector to create a signal.

With Multiscan food metal detectors, do more frequencies mean more false rejects?

Using up to five frequencies does not mean that Multiscan technology will create five times the number of false rejects. If you discover that any of rejects were false, you can quickly jump to the controls that need adjustment.
