For cultivating animal cells in bioreactors the maintenance of a fixed pH-value is of elementary importance. In a perfused cell culture system the pH-value is measured by electrochemical flow rate sensors. For the acceptance of a technical solution the integration in complex workplaces is necessary, thereby small size and low costs are the main features. For that a special measurement module was developed, consisting of measuring amplifier and microcontroller component with CAN-Bus-interface.
对于在生物反应器中培养动物细胞而言，维持固定的pH值至关重要。在灌注细胞培养系统中，pH值由电化学流速传感器测量。为了使技术解决方案被接受，必须将其集成到复杂的工作场所中，因此小尺寸和低成本是主要特点。为此，开发了一种特殊的测量模块，它由测量放大器和带有CAN总线接口的微控制器组件组成。
