Abstract
A method for the automatic identification of sensor sensitivity, according to which resistance of a specific magnitude is allocated to the sensor. The resistance is used to allocate the sensor to a specific sensor group with a predetermined sensitivity range.
Claims2
A method comprising the steps:
- producing a plurality of sensors wherein each sensor has an actual sensitivity;
- comparing the actual sensitivity of each sensor to a desired sensitivity to determine any deviation from the desired sensitivity;
- forming (x) groups of sensors each having sensitivities within a predetermined range of a desired sensitivity wherein (X) is ≧1;
- forming a group of resistors having different specific resistance values within a predetermined range for each group of sensors;
- connecting the group of resistors of specific resistance values to each group of sensors having a sensitivity within a predetermined range wherein the resistance values of the resistors are selected to identify the actual sensitivity of the sensors to which the resistors are connected within the group;
- and
- connecting at least one of the sensors with resistor to a detector means wherein the detector means measures the resistance of the resistor and determines the sensitivity of the sensor from the measured resistance for setting the operating measuring ranges of a manufacturing device based on the sensor sensitivity.
