Sanitary pressure transmitters are used in food or pharmaceutical production equipment to direct contact with raw materials to achieve pressure or liquid level measurement. LEEG's sanitary pressure transmitters truly meet the requirements of sterility and avoiding contamination to ensure the safety of food and drug production. The following features ensure the pressure transmitters are hygienic and sterile.
◼ No deposition, no scaling
The measuring part of the sanitary pressure transmitter is located at the front end of the corrugated diaphragm, which is in full contact with the measured medium. To avoid the deposition of particles in the measured medium, the surface roughness of the diaphragm is Ra＜0.4. In addition, the circumferential diameter of the circular diaphragm cannot be too small. The wave-shaped diaphragm with peaks and valleys of the diaphragm is smooth.
◼ No dirt
The quality of the diaphragm welding on the side of the sanitary pressure transmitter and the process connection are particularly important. For example, the pores caused by improper welding will become a hiding place for microorganisms. Improper process connection methods will cause the metal-to-metal rubber seals to age and fall off after multiple CIP/SIP processes.
◼ No corrosion
The CIP online cleaning of sanitary pressure transmitters uses acid cleaning liquid, alkaline cleaning liquid, disinfectant and hot water. Therefore, the measuring diaphragm and process connection metal parts are made of 316L stainless steel or better materials. The seals also need to be made of materials that are resistant to acid, alkali, and high temperatures.
◼ No leakage of harmful substances
The pressure measurement of hygienic pressure transmitters is that the pressure of the process medium is transmitted to the sensitive element through the corrugated diaphragm and the internal filling liquid. The filling liquid is a sanitary liquid that meets FDA standards. In the event of an unexpected rupture of the corrugated diaphragm, no harmful substances will be leaked.
