摘要： PROBLEM TO BE SOLVED: To provide a fuel property sensor capable of lessening an error in fuel temperature detection.SOLUTION: A storage member 31 which stores a thermistor 41 for detecting fuel temperature is composed of a cylinder section 312 and a bottom section 311 blocking one end of the cylinder section 312. The storage member 31 is inserted into a continuous passage 214 of an external electrode 21 and a continuous hole 223 of an internal electrode 22, and is electrically connected to the internal electrode 22. A coating section 42 coating the thermistor 41 touches the bottom section 311 located on the side of the storage member 31 closest to the central axis φ. Thus temperature detected by the thermistor 41 is more influenced by a heat quantity transmitted to the thermistor 41 from the fuel than a heat quantity transmitted to the thermistor 41 from an outside environment. As a result, a detection error of fuel temperature detected by the thermistor 41 is made smaller.

摘要： PROBLEM TO BE SOLVED: To provide a concentration measuring instrument for a liquid capable of excluding the effect of the leak resistance between detection electrodes in measuring the concentration of the liquid.
SOLUTION: The concentration measuring instrument for the liquid includes a first oscillation part 20 and a second oscillation part 25 and switches sw1 and sw2 are changed over by the pulse wave of two different duty ratios d1 and d2. In a case that one switch sw1 is turned on and the other switch sw2 is turned off, an operational amplifier 43 is operated so as to make the potentials of a non-reversal input terminal the same as a reversal input terminal and a detection electrode 41 is charged. Contrarily, in a case that one switch sw1 is turned off and the other switch sw2 is turned on, the detection electrode 41 is grounded on the positive side thereof, so that the charged detection electrode 41 is discharged. The difference based on the output voltages V(d1) and V(d2) of the operational amplifier 43 obtained by the charge and discharge is taken.
