CHAPTER 4Using the Gateway186“Sensor Tables” for conversion/linearization; if you intend touse a linear sensor, select “none”;Figure 200. Sensor type - Conversion settings - Sensor table - CounterNote: If a sensor table is entered for a non-linear sensor, the fol-lowing entries for Linear input value refer to the output val-ues of the linearization table and not to the voltagemeasured on the analog pin!• Linear input value - entry of the minimum and maximum valueof the range within which the sensor delivers measurements;Note: Due to its linear characteristic, a linear sensor is by defaultexactly defined by only two input values, the minimum andthe maximum. The resolution of the pulse counter is 16 bits.• Linear output value - entry of the minimum and maximumvalue of the linear output range which has to correspond tothe linear input value range, in the engineering units whichhave been selected;• Verifier - entry of the minimum and maximum value withinwhich valid sensor measurement results can be expected. Ifthe values are outside the preset thresholds, an invalid sensorvalue will be notified;• Display scale - enter the minimum and maximum value forscaling which should to be displayed on the trend graph“Sensor data graphic”.Digital sensor typesThe “Sensor type” window provides the following window areasfor digital sensor types:• Common settings - for entering the common definitions of thesensor type, especially determining its technology;• Digital sensor settings - for determining if the “digital sensor”is really a sensor or, instead, an actuator;
