Abstract
A fluid state detection sensor accurately detects a fluid state by suppressing the deterioration of a conductivity measurement accuracy due to its characteristics. The sensor includes an electrode section configured by a pair of electrodes arranged opposite each other, a conductivity acquisition unit detecting a resistance value from an inter-electrode voltage value acquired through the electrode section and acquiring a fluid conductivity, a controller executing entire sensor's processing according to a control program stored in ROM etc., a memory storing correction values for fluid whose conductivity is greater than a predetermined value calculated by a conductivity calculator, which calculates the fluid conductivity from the inter-electrode voltage value, a corrector correcting the conductivity calculator calculated conductivity using the correction value stored in the memory when the fluid whose conductivity calculator calculated conductivity is greater than the predetermined value, and an output section outputting corrected conductivity.
