Q.seriesGantner Instruments GmbH 674 Connecting the modules → Q.bloxx A107: Connecting sensorsTipInformation about the types of circuit and the respective advan-tages and disadvantages can be found in Section 6.3, Connectingsensors w ith sensing leads, page 143.4.14.5 ThermocoupleFor connecting thermocouples you need a special connectingplug which contains the comparative measuring point (cold pointcompensation) required for thermocouples. The plug can beobtained under the designation Q.bloxx Terminal CJC-A107 fromGantner Instruments GmbH. You can connect the following typesof thermocouple: B, E, J, K, L, N, R, S, T and U.Alternatively, you can also use two thermocouples or a referencetemperature source.TipYou will find information on the comparative measuring point andon the measurement with a reference temperature source inSection 6.6, Measuring w ith thermocouples, page 148.Fig. 4-57 A107, measurement w ith thermocouple using Q.bloxxTerminal CJC-A107.4.14.6 Full-bridge transducerWith (resistive) full bridges (strain-gauge full bridges) four con-nections are occupied. If the sensor has sense leads, you shouldconnect them to the relevant supply lines (1 and 5 or 6 and 10).The bridge excitation voltage is 2.5 V.3, 7 (–)2, 6 (+)Q.bloxx Terminal CJCCJC–CJC+
