The HPM720 sanitary pressure transmitter utilizes a flat membrane to directly detect pressure signals, employing a silicon pressure core as the sensitive component and standard silicone oil or olive oil as the pressure transmission medium. Constructed with 316L stainless steel at the measuring end, it boasts a compact design, corrosion resistance, vibration resistance, and extensive temperature compensation capabilities. This transmitter detects pressure directly through an exposed diaphragm on the chuck's end face, eliminating issues such as scaling, unhygienic blockages, and sticky pressure obstructions. It is particularly well-suited for use in the medical and food industries, offering solutions for hygienic requirements, viscous fluid pressure, and level measurements to address challenges like scaling, blockages, cleaning, and hygiene concerns.
