Stringent Requirements for Pressure Measurement Equipment in the Food Processing Industry

In food and beverage production lines, pressure transmitters need to remain in long-term contact with corrosive media such as acidic and alkaline solutions, high-temperature steam, while also meeting the hygienic requirements of FDA and EHEDG for food-contact materials. Traditional pressure transmitters often cause medium penetration due to insufficient sealing, or contamination risks due to substandard materials. The CS-PT700 pressure transmitter adopts an integral 316L stainless steel structure, and its surface roughness Ra≤0.8μm design effectively prevents microbial residue. Combined with an IP68 protection rating and a wide operating temperature range of -40℃~125℃, it is perfectly suited for typical process scenarios such as pasteurization and high-pressure homogenization.

Comparison of Core Technical Parameters and Industry Standards

Compared with similar products such as the SUP-P300Z pressure transmitter, the CS-PT700 has significant advantages in key indicators: measurement accuracy reaches ±0.1%FS (full scale), response time is ＜1ms, and overload capacity is up to 3 times the measuring range. Its unique diaphragm welding technology has passed ISO 15859 aerospace material standard testing, ensuring long-term stability under frequent CIP/SIP cleaning. Compared with the CS-PT800 series, this model is specially optimized for food-grade O-ring materials and complies with the requirements of 3-A Sanitary Standards 74-05. Technical evaluators can quickly understand the core differences through the table below:

Typical Application Scenarios and Customer Cases

In a sterile filling system for dairy products, the CS-PT700 pressure transmitter successfully replaced a certain imported brand, achieving a pressure control fluctuation accuracy of ±0.5kPa for fermentation tanks. A multinational beverage group adopted a combined solution of CS-PT607A and CS-PT700 in the CO2 injection process at its Asian factory, extending the production line shutdown cleaning cycle from 72 hours to 120 hours. These cases demonstrate Shenghongchuang Instrument's technical accumulation in the field of food-grade sensors—as a high-tech enterprise in Xixian New Area, we hold 12 pressure measurement-related patents, and all products undergo 48-hour aging tests and HART protocol communication verification before leaving the factory.

Selection Decision Tree for Technical Evaluators

For different process sections in food processing, it is recommended to select according to the following logic: for the sterilization stage of liquid products, priority should be given to the hygienic flange connection of the CS-PT700; for powder material conveying systems, the explosion-proof version of the CS-PT602 can be selected; for smart factories requiring remote monitoring, the CS-PT831 integrated with IO-Link functionality is recommended. It is worth noting that although traditional models such as KAP32M cost 15%-20% less, they have obvious shortcomings in cleaning resistance and long-term drift indicators. Shenghongchuang provides free sample testing services, and the technical team can assist in completing the equipment validation documents required for GMP certification.
