Abstract
Official abstract text for this publication.
A liquid state detection sensor includes: an electrode part, the electrode part having a pair of electrodes provided so as to be opposed to each other; a voltage value acquisition time period setting unit configured to set a voltage value acquisition time period, the voltage value acquisition time period being a length of a time period during which an inter-electrode voltage value of the pair of electrodes of the electrode part is acquired; a voltage value acquisition unit configured to acquire the inter-electrode voltage value in the voltage value acquisition time period; and an electrical conductivity calculation unit configured to calculate an electrical conductivity of the liquid on the basis of, among the inter-electrode voltage value acquired by the voltage value acquisition unit, the inter-electrode voltage value acquired after a predetermined time period has elapsed since a start of the voltage value acquisition time period.
First claim
Opening claim text (preview).
1 . A liquid state detection sensor configured to detect a state of a liquid, the liquid state detection sensor comprising: an electrode part arranged in a flow passage of the liquid, the electrode part having a pair of electrodes provided so as to be opposed to each other; a voltage value acquisition time period setting unit configured to set a voltage value acquisition time period, the voltage value acquisition time period being a length of a time period during which an inter-electrode voltage value of the pair of electrodes of the electrode part is acquired; a voltage value acquisition unit configured to acquire the inter-electrode voltage value in the voltage value acquisition time period; and an electrical conductivity calculation unit configured to calculate an electrical conductivity of the liquid based on, among the inter-electrode voltage value acquired by the voltage value acquisition unit, the inter-electrode voltage value acquired after a predetermined time period has elapsed since a start of the voltage value acquisition time period. 2 . The liquid state detection sensor according to claim 1 , wherein the predetermined time period is a time period from the start of the voltage value acquisition time period until the inter-electrode voltage value is stabilized. 3 . The liquid state detection sensor according to claim 1 , wherein the electrical conductivity calculation unit is configured to calculate the electrical conductivity of the liquid based on an average value of the inter-electrode voltage value acquired after the predetermined time period has elapsed in the voltage value acquisition time period.
