Abstract[English]
Provided is a foreign matter deposition amount estimation device capable of estimating a deposition amount of foreign matter. Provided are a conductive casing 212 having an inlet 225A and an outlet 225B, a conductor member 214 disposed at an inner side of the casing 212 with a gap t from the casing 212, a measurement device 216 that measures electrostatic capacitance between the casing 212 and the conductor member 214, and an arithmetic device 218 that estimates, from a change in electrostatic capacitance, a foreign matter deposition amount in the casing 212. The conductor member 214 includes a communication port 236.[French]
La présente invention concerne un dispositif d'estimation de quantité de dépôt de matière étrangère capable d'estimer une quantité de dépôt de matière étrangère. L'invention comprend un boîtier conducteur (212) pourvu d'une entrée (225A) et d'une sortie (225B), un élément conducteur (214) disposé d'un côté interne du boîtier (212) avec un espace (t) par rapport au boîtier (212), un dispositif de mesure (216) qui mesure la capacité électrostatique entre le boîtier (212) et l'élément conducteur (214), et un dispositif arithmétique (218) qui estime, à partir d'un changement de capacité électrostatique, une quantité de dépôt de matière étrangère dans le boîtier (212). L'élément conducteur (214) comprend un orifice de communication (236).
