3 Technical Description3 Technical Description3.1 The SensorThe CarboSen1000 is a sensor system for the detection of flammable gases such as CO, H 2or C x H y . In this manual, these gases are also referred to as CO equivalent (CO e ).The sensor system consists of the sensor and the sensor electronics. The unit, comprising thesensor element, sensor housing and sensor signal cable, forms the sensor, which is used todetect the measured variable. The sensor electronics enable temperature compensation duringoperation, flexible control of the sensor and the acquisition of all sensor signals.The CarboSen1000 1000 is a high-resolution measuring system for the detection of small CO econcentrations in the range of 0 - 3000 ppm (ideally up to 1000 ppm). In the ST version, theelectronics are integrated in the head of the sensor.The CarboSen1000 functions on the principle of solid-state electrolysis. The technology usedfor this method is well known and widely used in the form of the lambda sensor. However, unlikethe lambda sensor, which measures oxygen on the basis of the Nernst principle, theCarboSen1000 functions according to the Non-Nernst principle. By varying the geometry, materialand electrical wiring, sensors working according to the Non-Nernst principle can also detectother gases such as CO, H 2 , and HC.To operate the sensor, it first has to be heated to operating temperature. This is achieved bymeans of a heating structure, which is affixed to the back of the sensor element. The resistanceof the platinum heating spiral has a defined temperature dependence. This enables theoperating temperature of the sensor to be set. This temperature is 630°C and is set automaticallyby the electronics and kept constant during operation. To this aim, the electronics automaticallydetermine a cold resistance of 20°C when the sensor system is commissioned.The sensor temperature can be varied for special applications. For this purpose, the relevantparameters have to be reprogrammed. Upon customers’ request, this can be carried out eitherat LAMTEC or on site (with the appropriate programming unit). If the operating temperature ischanged, so is the sensor characteristic. Increasing the temperature of the sensor results inreduced sensitivity, i.e. the sensor is less sensitive to CO e and the curve is flatter. The sensordynamics become faster, i.e. the response and decay times are accelerated.Fig. 3-1 Principle of the Non-Nernst sensor9
