Title:
SENSOR
Document Type and Number:
WIPO Patent Application WO/2017/187770
Kind Code:
A1
Abstract:
Provided is a sensor that determines the state of a fluid in more detail. This sensor (1) for determining the state of a fluid inside a device comprises a characteristic amount acquisition unit (10), a timekeeping unit (20), and a state determination unit (30). The characteristic amount acquisition unit (10) finds the permittivity and the electrical conductivity of the fluid. The timekeeping unit (20) measures the time from when the fluid was introduced into the device. The state determination unit (30) determines the state of the fluid on the basis of the permittivity and the electrical conductivity found by the characteristic amount acquisition unit (10) and the time measured by the timekeeping unit (20).
