Hygienic Pressure Transmitter, often known as hygienic Pressure Sensor, English name Hygienic Pressure Transmitter /Sanitary Pressure Sensor, is to ensure the health and safety of food and drugs, Ensure that food and drugs will not contact and mix with toxic, harmful, contaminated material components or substances not suitable for confusion through the contact pressure transmitter, and the material, structure, performance, processing (such as welding, polishing, etc.), and clean treatment of the pressure transmitter in direct contact with food and drugs have a series of health requirements. To meet these special requirements is the sanitary pressure transmitter/sanitary pressure sensor. HWPB3 sanitary monocrystal silicon pressure transmitter meets the following series of health requirements: In terms of non-toxic and harmless material requirements, including: according to different conditions, different grades of stainless steel materials (304L, 316L, 410, 409, 329) are selected; All kinds of polymer materials, all kinds of rubber elastomer materials, adhesives, lubricants, measuring conductive fluid materials, thermal isolation materials, plating materials, etc. shall not contain toxic and harmful components, and shall not have toxic and harmful components oozing or infiltrating; The structure requires smooth surface, no dead corners, not easy to accumulate residue, not easy to pollute, easy to wash (often using fast opening clamp interface) and easy sterilization and disinfection; Anti-contamination requires strict sealing isolation, anti-virus, harmful and pollutant entry and discharge, high temperature disinfection and sterilization; Processing requires a certain degree of finish and weldability; Maintenance requires suitable cleaning agents, easy cleaning of the internal and external surfaces, convenient in-place cleaning (CIP) and in-place sterilization (SIP), etc.
