Disclosed is a pressure detection device configured to detect pressure intensity in a sealed cavity of a cooking appliance, comprising: a pressure sensing assembly comprising a fixed part and a movable part, in which the movable part moves relative to the fixed part when a pressure change in the sealed cavity is sensed, so as to cause a sensing parameter of the pressure sensing assembly to change; and a detecting unit connecting with the pressure sensing assembly and can acquire the pressure intensity in the sealed cavity according to a current sensing parameter of the pressure sensing assembly. The pressure sensing assembly further comprises a flexible sealing sheet disposed at an open end of the body portion to seal the open end, and configured to be deformed towards the pressure chamber when an air pressure in the sealed cavity is greater than an air pressure in the pressure chamber.

Disclosed is a pressure gauge comprising a pressure sensor and a pressure transmitter connected upstream of the pressure sensor and having an isolation diaphragm enclosing a pressure receiving chamber. A hydraulic pressure transmission path is connected to the pressure receiving chamber and is filled with a pressure transmitting fluid that transmits the pressure acting on the outer side of the isolation diaphragm to the pressure sensor The pressure gauge allows functional impairments of the pressure gauge to be detected early without having to change the pressure acting on the outer side of the isolation diaphragm. The pressure transmitter comprises an electronically activatable deflection device which is designed in such a way that, when activated, it exerts a constant force deflecting the isolation diaphragm, on the isolation diaphragm, or on an element connected to the isolation diaphragm.

A first differential pressure that is a differential pressure as a pressure difference between a high pressure side and a low pressure side in a filtration device is detected at a first time as a time while the filtration device filters a liquid. A remaining life that indicates how long the filtration member is usable from the first time is obtained based on the first differential pressure and differential pressure characteristics.
