Sensors for the Washdown Area

The sensors for the washdown area are ideal for use in spraying applications in the food, beverage and packaging industries. The high-quality stainless steel 316L housing makes them robust and corrosion-resistant.
Thanks to the high IP69K degree of protection, the sensors can be integrated into and on systems where they can withstand high-pressure cleaning at up to 100 bar and water temperatures of up to 80 °C. The sensors are also ECOLAB certified and therefore resistant to aggressive cleaning agents.

Photoelectronic sensors use light to detect or count objects contactlessly and to measure distances using light. The high-quality 2K miniature design in stainless steel 316L (1.4404/V4A) is available as a reflex sensor with background suppression, energetic reflex sensor, through-beam sensor, universal retro-reflex sensor and retro-reflex sensor for transparent objects. Depending on the intended use, different types of light, such as blue light, red light or red laser light, are available.

The photoelectronic sensors in 2K format are part of the PNG//smart family. They have an aligned optical axis and offer smart communication via IO-Link and condition monitoring.

Detection of Biscuit Cookies

In the production of cookies, the objects must be transported and gripped between different processes on multi-lane conveyor belts. After baking in the oven, they are individually conveyed on rails and prepared for the packaging process. They must be counted before gripping and moving. For this purpose, a reflex sensor with background suppression is installed above each lane on the conveyor line, which detects the cookies from the front edge. Thanks to the stainless steel 316L housing, the sensors are ideal for hygienically demanding cleaning at high temperatures.

Leading Edge Detection of Soft Cheese

In the production of soft cheese, the wedge-shaped pieces of cheese are transported to the packing station on conveyor belts. In order to trigger the packaging process on a special bagging machine, to monitor the distance between the objects and to prevent jamming, the front edges of the cheese pieces must be reliably detected. For this purpose, a through-beam sensor is installed on the side in the stainless steel 316L housing with opposite receiver. Thanks to the cleaning agent-resistant and robust stainless steel housing with IP69K degree of protection, even high-pressure cleaning at up to 80 °C is possible.

Laser distance sensors Time-of-Flight with wintec are powerful transit time sensors that work with a red laser. This means that they cover large working ranges and detect objects safely and reliably even from a large distance. 

The latest wintec generation with DS technology delivers precise results up to 10 meters and sets itself apart in particular by the fact that it reliably detects objects regardless of their color or surface condition, such as gloss – even in extreme inclined positions.

Detection of Food

In the further processing and packaging of food, these are recognized and counted in machines and systems that are subject to strict cleaning and disinfection regulations. Thanks to their high chemical resistance and IP69K degree of protection, the sensors are ideally suited for use in systems like these.

Cheese Block Reject Check

When producing hard cheese, it is important to ensure the exact positioning of the cheese on the conveyor belt. The sensors are able to detect the blocks of cheese in fresh, glossy condition regardless of inclined angles – and also meet the high requirements of the food industry thanks to the cleaning agent-resistant housing.

Fork Sensors P1HJ



 
  • Corrosion-free stainless steel 316L housing in washdown design with ECOLAB
  • Collimated laser beam (0.35 mm diameter over the entire fork width) for detecting even the smallest parts (40 µm)
  • Detection of transparent objects
  • High switching frequency (10 kHz)
  • Teach-in key and external teach-in

The photoelectronic fork sensors work with a fine laser beam according to the emitter-receiver principle and thus enable reliable detection of objects – even of transparent or very small parts. During installation, the visible red laser light enables easy alignment of the sensor to the object, the emitter and receiver are permanently installed and do not have to be aligned with each other. The flexible fork widths between 50 and 220 mm enable versatile use of the fork sensors.

Fork Sensors in Use – Special Design for Special Challenges

Position Monitoring of Crown Corks

After closing the filled bottles, it must be checked on the running belt whether the crown corks or screw caps have been correctly attached. The fork sensors enable precise detection of transparent objects even at high speeds. Thanks to their IP69K degree of protection and corrosion-resistant stainless steel 316L housing, they are ideal for use in wet areas.

Full-Metal Ultrasonic Sensors in Use – Ultra-Robust

Fill-Level Measurement of Spices in Frozen Pizza Production

Frozen pizzas are produced and the toppings added in highly automated production facilities. Spices such as oregano are sprinkled on top of the pizzas after the toppings have been added. The spice mixture is located in an open container directly above the conveyor belt. An ultrasonic distance sensor in a stainless steel housing monitors the container to detect the exact fill level at all times so the container can be refilled in good time.
