| description | The sensor apparatus includes a sensor device having a control current (IH) flowing through it, a sensitivity and a temperature dependence of the control current characterized by a temperature coefficient, and a temperature compensating circuit for compensating temperature changes adversely effecting the sensitivity of the sensor device. The temperature compensating circuit includes a circuit portion which sets or adjusts the temperature coefficient of the control current(IH) according to changes in the temperature dependent internal resistance of the sensor device so that changes in negative temperature coefficients of other physical quantities determining the sensor sensitivity are compensated. |
