PROBLEM TO BE SOLVED: To provide a sensor circuit that can discriminate the output values of sensors when disconnection or short circuits occurs or input is made to the sensors beyond the allowable values of the sensors or the minimum values and maximum values of the sensors when the sensors normally operate, and to provide a bearing with sensor provided with the sensor circuit. SOLUTION: The sensor circuit is provided with at least one sensor 4 and 5 supplied with electric power from a constant-voltage circuit Vdd and output limiting circuits 10 and 15 which respectively limit the outputs of the sensors 4 and 5. The circuits 10 and 15 controls absolute values in the output ranges of the sensors 4 and 5, when the sensors 4 and 5 are operated between a first voltage higher than zero (0) and a second voltage lower than the absolute value of the output voltage of the constant-voltage circuit Vdd. When the outputs of the sensors 4 and 5 become zero (0), the circuit Vdd discriminates that disconnection occurs and, when the outputs become higher than the second voltage, the circuit discriminates that the outputs of the sensors 4 and 5 are abnormal.
