　　Food quality and safety have always been people's attention. It has become increasingly prominent in food safety issues. my country has paid more and more attention to food safety, so it puts forward refined requirements for food testing technology. The long -term widely used physical, chemical, instruments and other methods can no longer meet the analysis of modern food. In food testing technology, sensors play an important role, which will help the data collection of food temperature and location. The application of sensors not only improves the output of food, but also guarantees the safety of food.

　　Food -grade temperature sensor refers to the temperature sensor that is generally used in the food processing industry and the pharmaceutical processing industry. Also called sanitary temperature sensor.

　　Food -grade temperature sensor structure features:

　　Due to high hygiene requirements, the surface of the product should be left as little as possible, and the structure that is not convenient for cleaning and cleaning, and complies with the installation method of food or drug processing equipment systems, such as DN25, DN50 card holes, and spherical pads. , Or a full -closed waterproof and anti -corrosion structure, some special occasions reach the IP68 protection level.

　　Food -grade temperature sensor material requirements:

　　General food -grade temperature sensors, use stainless steel in all stainless steel or in connecting liquids, contacting products and measurement medium. The material is 316 or 316L or above. On the wiring box and attachment materials (referring to the subsidiary accessories of non -contact products), at least 304 or 304 stainless steel is used, and a small amount of low -end products use aluminum alloy attachments. In some special occasions and sealing materials, medical or food -grade non -metal materials can also be used, such as medical silicone, medical PTFE and food lubricants. These structures are convenient for CIP cleaning (pickling) and can reach the relevant corrosion level.

　　Most of the food -grade temperature sensors use platinum resistors, such as PT100, PT1000. But in some special occasions, such as some checked meat processing products, using pierced thermocouples, bending armor thermocouples are still used on Food and pharmaceutical industry. Most of the sanitary temperature sensors use PT100. The accuracy level is generally A or AA. It requires higher occasions and uses a double -branch platinum resistor with redundant design.
