Sensors Promise Safety, Better Quality for Food Processors and Consumers

Sensor technology is one of the technologies that will play a major role in the future. It can be used in all sectors of industry to give products added value that make them more competitive. Sensor technology is a rapidly growing area of research. Many products incorporating sensor technology are already on the market and it promises to continue to play a critical role in technologies of the future. 

Sensors and sensor systems perform a wide range of sensing functions. They enable products and systems to capture process and communicate information about the status of the system in which it is placed. Sensors are able to capturing information on the chemical composition, texture and morphology, large-scale structure, position and motion of systems in which they are applied. It is a characteristic feature of a sensor that the device is tailored to the environment in which it is to operate. 

Technical change-agents affecting sensor markets today include developments in smart sensors, sensor buses for distributed networks, semiconductor technology, and sensor miniaturization, in general, because industrial sectors are constantly looking for cutting-edge high performance at a lower cost, smart sensors using microcontrollers are adding intelligence and functionality to various sensor technologies and providing simpler, more intuitive set-up. Innovation will move industrial sensor markets into adopting new technologies including smart sensor capabilities, wireless communications, microelectromechanical systems (MEMS)-based components, plug-and-play sensors, and increased precision. Many of these advanced technologies are available now. All over the world, food processors are always searching for ways to meet changing consumer demands while delivering products that meet expanding markets for healthy, convenient foods. The food industry thrives on process techniques that take environmental constraints into account, meet food safety requirements and produce high quality products for consumers.

Process efficiency in the food industry can be achieved by incorporating advanced technologies that lower unit costs and improve overall product quality, contributing to higher profits. Finding ways to reduce the number of unskilled human links in automatic material handling systems could be an important breakthrough in reducing workplace injuries resulting from highly repetitive activities. Developing better methods of producing food and enhancing the nutritional value of foods are important, as well.
The sensors are designed to ensure hygienic operation, as well as to withstand the effects of the aggressive cleaning solutions and rapid temperature changes. With inductive and capacitive proximity sensors; flow, temperature and pressure monitors; and photosensors, this product range serves virtually every sensing requirement of food industry. A wide range of accessories, including time- and cost-saving adjustable mounting systems, complements the sensors. manufactured from stainless-steel.

Sensors Flush For Food

Flush-mountable inductive proximity sensors which are specifically designed to withstand the rigours of food-industry applications, are available in the market. Some models which are available in both flush-mounting and non-flush-mounting versions.

All of the new sensors have corrosion-resistant stainless-steel bodies, with food-friendly PEEK sensing faces. They offer an IP69K protection rating, and they can operate continuously in ambient temperatures of up to 100ºC without compromising performance or reliability. Full compatibility with CIP operations is assured. The new sensors offer the full benefits like ultra-stable operation, exceptional reliability and extended sensing ranges. New range of flush mounting pressure sensors offer a very attractive choice for applications in the food, beverage and pharmaceutical industries.  All sensors in the new range use innovative ceramic cell pressure sensing technology which provides stable, accurate operation with freedom from ageing effects, and which ensures outstanding resistance to over-pressure damage.

Photosensors Enjoy A Good Wash

Photosensors with their IP68 protection ratings and stainless-steel bodies are an ideal choice for food-industry and other demanding applications where they may be subject to pressure washing or exposure to aggressive cleaning chemicals. 

It offers extended sensing ranges, combined with total operating ability over a temperature range of –20ºC to +80ºC. The sensors are manufactured from food-grade materials, and feature smooth, shatterproof lens covers, which resist the build-up of contaminants.  For ease of adjustment, OG Wet-Line sensors incorporate Touch-to-Teach setting technology. Users simply press a button once with the target in place, then again with no target, and the sensor automatically adjusts itself for optimum performance.
