Can food hygiene sensors use an inverted core for measurement?


No, the sensors used for food hygiene often require regular disinfection and cleaning. There is still a 0.1mm assembly gap between the inverted sensor and the housing, which can retain deteriorated media, causing secondary contamination. At the same time, inverted sensors cannot withstand high-temperature disinfection, often causing temperature hysteresis errors during normal operation. In negative pressure operation, it can even lead to the sensor being sucked out of the housing. Therefore, it is necessary to use a truly fully welded hygienic pressure sensor, such as SMP2200, SMP2300I, SMP2300II.
