Product brief: The sanitary pressure transmitter is a type of pressure transmitter whose zero and full-scale outputs can be accurately adjusted. It is available in two versions: conventional intelligent and standard intelligent. Its circuit conversion module is housed in the attractive and popular 3351 series enclosure. It is widely used for pressure measurement and control in industrial processes across industries such as food, pharmaceuticals, brewing, and fermentation. Thanks to its excellent reliability, wide adaptability, as well as the flexibility and diversity of its products, its pressure connection interfaces can be implemented via imperial threads or clamps and sanitary pipes; these clamps and sanitary pipes form part of the system, and other pressure connection options are available depending on specific requirements. Main uses: 1. Measurement in hygiene-related fields such as food, beverages, and pharmaceuticals, as well as in the fine chemical industry ； 2. Pressure measurement in various pipes and containers ； 3. Measurement of thermal media, corrosive media, high-temperature viscous media, or crystalline media ； 4. Thermoelectric, metallurgy, machinery, light industry, hydraulics, shipbuilding, and diesel engine industries. Key features: 1. The sanitary pressure transmitter is designed to meet the requirements of the sanitary industry, featuring high precision and a long service life. Its high level of protection, fully sealed welding, and compact design ensure that it can be used in high-temperature environments during cleaning processes. It boasts excellent temperature compensation capabilities, which guarantee the reliability of its pressure measurements. 2. The sanitary pressure transmitter is formed by incorporating a welded-sealed sanitary diaphragm structure. Its welded-sealed, hygienic diaphragm device comes in various process connection configurations, and is particularly suitable for pressure measurement in high-temperature, high-viscosity, crystalline media, as well as in situations prone to clogging. It is also appropriate for pressure measurement in hygienic and pharmaceutical applications. 3. The transmitter is designed in a fully hygienic stainless steel format; all connections are sealed with stainless steel, eliminating any potential hygiene hazards, and the enclosure features a laser-etched nameplate. 4. The sensitive element of the transmitter is a high-sensitivity silicon piezoresistive diaphragm. The sanitary-type pressure transmitter features imported high-precision integrated amplification circuits, offering good stability and strong interference resistance. The entire unit is assembled using standard processes and undergoes rigorous testing, thus meeting the technical specifications of similar imported products. It boasts stability, reliability, and compatibility in industrial control applications. 5. The sanitary pressure transmitter features a compact and delicate design, with various materials available for the parts that come into contact with the medium. It features reliable performance and high measurement accuracy; moreover, thanks to the use of intelligent electronic components, it comes equipped with HART or FF communication protocols, enabling easy calibration or configuration. 6. The product features a standard modular design with a consistent structure, enabling easy replacement or upgrading. The sensors are available in a variety of optional materials to meet different on-site requirements. 7. The measuring section is located on the front-end corrugated diaphragm, which is in full contact with the medium to be measured. To prevent the deposition of particles and other substances present in the medium, its surface roughness Ra must be less than 0.38 μm. Additionally, the circumferential diameter of the circular diaphragm should not be too small, and the surface of the diaphragm, with its ridges and valleys, must be smooth to avoid deposition. 8. No scaling; if deposits turn into scale, it is difficult to remove them completely using CIP online cleaning and SIP online sterilization, and inspections are also difficult to carry out without disassembly. 9. Preventing contamination: The quality of welding the diaphragm on the side of the transmitter, as well as potential issues related to the process connections, are receiving increasing attention. For example, pores formed during welding can serve as habitats for microorganisms; even sterilization using steam at 121°C for 30 minutes cannot eliminate them completely. Moreover, the use of inappropriate process connection methods can cause the rubber seals between metals to age and deteriorate after multiple CIP/SIP cycles, thus becoming breeding grounds for microorganisms and affecting all subsequent batches of products. 10. Non-corrosive: For CIP online cleaning, acidic cleaning solutions, alkaline cleaning solutions, disinfectants, and hot water are used. The measuring diaphragm of sanitary pressure transmitters as well as the metal parts used for process connections are made of 316L stainless steel or a material of even higher quality; seals also need to be made from materials that are resistant to acids and alkalis as well as high temperatures. 11. It does not release harmful substances; pressure measurement is achieved by transmitting the pressure of the process medium to the sensitive element through a diaphragm and an internal filling fluid, with the filling fluid being a hygienic liquid that meets FDA standards.
