Sensors for the Food & Beverage Industries sensors Sensor Solutions Production, Packaging & Quality Control with Optical Sensors A cooperation with the market leader for beverage filling systems, Krones AG, Neutraubling, triggered our Food & Beverage business field in the late 1990’s. PreSens supplies sensors for checking the air-tightness of packaging and a special system for determining the penetrability of oxygen in PET bottles at companies such as Nestlé, Heineken or Danisco. Reliable results can be obtained in an easy, time-saving way and can help to ensure the filling quality and long-term...

SENSOR SOLUTIONS Packaging Development: Material Research: Contactless & Non-Destructive Determi­ nation of Oxygen Ingress in Food Packaging Oxygen Transmission Rate of Synthetic Materials Oxygen inside packaging can lead to oxidative deterioration of foods or beverages. The amount of tolerable oxygen inside packaging can differ greatly according to the packed product. PreSens oxygen sensors help finding the right packaging material for your product. Materials with different oxygen permeability or the tightness of closures can easily be determined in contactless measurements with oxygen sensor...

Sensors for the Food & Beverage Industries Featured Systems Fibox 4 trace + POF + Permeation Cell Microx 4 + Needle-type Oxygen Microsensor NFSG The Fibox 4 trace can be used with sensors covering a measurement range from 1 ppb up to 100 % oxygen. These sensors can be integrated in the permeation cell and are read out through an optical window via polymer optical fiber (POF). With this system the oxygen transmission rate through low- and high-barrier material films can be determined. This portable oxygen meter combined with a needle-type microsensor offers easy assessment of the oxygen content...

FEATURED SYSTEMS Fibox 3 LCD trace + Oxygen Probe for In-line Measurement OIM Fibox 3 LCD trace + Varivent Valve OIM-Var The Fibox 3 LCD trace oxygen meter can be combined with the Oxygen Probe for In-line Measurement OIM. The probe is available for measurements in different oxygen ranges, stands autoclaving, SIP & CIP. The probe can be inserted into ports or openings. The system is ideally suited for trace oxygen measurements in glove boxes. The solution for oxygen measurements in breweries: The Oxygen Probe integrated in a Varivent Valve OIM-Var can be installed in steel pipes. They are read...

Sensors for the Food & Beverage Industries Featured Applications Oxygen Transmission Rate Measurements in Material Research C. Huber, S. Sängerlaub & K. Müller, Cooperation: PreSens,Fraunhofer Institute for Process Engineering and Packaging, and TU Munich, DE In cooperation with the Fraunhofer Institute PreSens developed a new measurement system for testing synthetic materials on oxygen permeability. Unlike the currently used systems with electrochemical or barometrical sensors it is designed for optical measurement. The Fibox 4 trace together with chemical optical sensors for different measurement...

Oxygen Ingress Measurements in Different PET Bottles Oxygen causes chemical processes decreasing the shelf life and flavor quality of beverages. In order to improve the oxygen barrier properties of PET bottles tests were conducted using the Fibox 3 LCD trace oxygen meter and PreSens trace oxygen sensors. As can be seen in the figure, coated PET bottles (B) already have less oxygen ingress than untreated bottles (A). If the bottle material additionally contains oxygen scavengers (C + D), oxygen ingress can be reduced significantly. The shelf life of a product filled in this bottle will be prolonged...
