Omron has announced a transparent object sensor specifically designed for the food and beverage industry – offering superior detection of objects such as glass bottles, PET bottles, transparent trays and packaging film
Further expanding Omron’s sensing solutions, the E3S-DB represents a new benchmark in industrial sensors for transparent object detection. A high sensing stability makes this new sensor well suited for detecting all kinds of transparent objects found in today’s food and beverage packaging processes.
To enable high precision detection and positioning on conveyors where the smallest of gaps between products exists, the E3S-DB is also available in narrow beam models with a convergent beam that has a focused spot size of just 2mm.
Advanced features
To meet the trend towards the use of thin PET bottles in the beverage industry, the E3S-DB applies a technique known as P-Opaquing, which offers increased detection stability through special polarising filters for PET objects. A further advanced feature automatically compensates for light level changes caused by ambient conditions or contamination.
Performance
Developed in close conjunction with customers who produce some of the world’s leading branded food and beverage products, the E3S-DB features an optical system that enables sensing with low hysteresis and high dynamic range. This results in an increase in performance. For instance, the E3S-DB is capable of detecting just three percent light intensity attenuation at a distance of up to four metres.
The advanced optical system of the E3S-DB increases stability performance by completely cutting off even the smallest amounts of stray light that might interfere with glass bottle detection. Known as the ‘bottle-lens-effect’, this unwanted magnification of light intensity commonly causes disruption of glass bottle detection on packaging lines with traditional sensing technology.
User friendly
Thanks to Omron’s newly developed ‘Smart Teach’ function, setting up the E3S-DB can be achieved both quickly and with the minimum of effort. Smart Teach simultaneously provides setting of the light intensity threshold and fast teaching all in one action. To achieve the maximum operating stability, all an operator has to do is manually pre-select (using a trimmer switch) the ideal operational threshold level for the given sensing objects. Then, by simply pushing the ‘teach’ button, the sensor automatically adjusts light emission power and sensitivity according to sensing distance and selected threshold. The sensor is taught to the reflector and not the object, thus ensuring once the sensor is configured it will detect any object with high stability, without the need for readjustment.
Information about the operational threshold of the sensor is always clearly visible and the operator can easily copy the setting from one sensor to another. This saves considerable time when setting up multiple sensors on the same production line, or in the case of maintenance.
The E3S-DB’s user friendliness is further enhanced by a handy, time saving PC monitoring tool. The tool can be used to verify the optimum setting for any application and is an ideal support tool for maintenance engineers with respect to fault diagnostics. The PC tool provides instantaneous operation feedback and light attenuation levels, to show clearly the status of the application.
