The sanitary pressure transmitter, also known as the sanitary pressure sensor (Hygienic Pressure Transmitter /Sanitary Pressure Sensor), is to ensure the sanitation and safety of food, drugs and to ensure that food and drugs will not pass through the contact pressure transmitter with toxic, harmful, The material, structure, performance, processing (such as welding, polishing, etc.), clean treatment, etc. of the pressure transmitter that has contaminated substances or substances that are not suitable for confusion, and which are in direct contact with food and drugs. Series of hygiene requirements. To meet these special requirements is a sanitary pressure transmitter.
