Sensor assembly, sensor controller and current-measuring circuit
First Claim
1. A sensor assembly for a current-measuring circuit and operatively connected to a power supply disconnection apparatus of a motor vehicle on-board circuit, the sensor assembly comprising:
- a first sensor apparatus arranged on a common circuit carrier to measure an intensity of an electrical current and output the measurements to a sensor controller via a first connection;
a second sensor apparatus arranged on the common circuit carrier to measure an intensity of the electrical current and output the measurements in analog form to the sensor controller via a second connection, the second sensor apparatus not including an analog-digital converter; and
a first analog-digital converter arranged on the common circuit carrier to convert analog measured values of the first sensor apparatus to digitized measured values,wherein the sensor controller has a microcontroller to evaluate the measured values from the first sensor apparatus and the second sensor apparatus and thereby control a power supply based upon the evaluated measured values.

Abstract
A sensor assembly for measuring an intensity of a current includes a first sensor apparatus configured to record an intensity of the electrical current with contact, a second sensor apparatus configured to record an intensity of the electrical current, the second sensor apparatus having a common measurement range with the first sensor apparatus, and a first analog-digital converter configured to convert analog measured values into digitized measured values. The first sensor apparatus, the second sensor apparatus and the first analog-digital converter are arranged on a common circuit carrier.
