Technical Examples
  1. A breath alcohol measuring device is provided with a pressure sensor (2) for detecting a signal representative of the breathing air flow and with an electrochemical sensor (1) for detecting a signal representative of the alcohol content in the breathing air and with evaluating means for processing the signals and for determining the breath alcohol concentration. Such a breath alcohol measuring device has a simple design and high measuring accuracy. The pressure sensor (1) and the electrochemical sensor (2) are connected for this purpose with a delta-sigma analog-digital converter (8), which converts the sensor signals directly into digital measured values for determining the alcohol concentration. The pre-amplifiers needed hitherto become unnecessary as a result, which has a number of advantages.
