Research on Metrological Characteristic of Micro-Differential Pressure Sensor in Draw Resistance Device

Abstract:

Micro-differential pressure sensor is one of the core components in the draw resistance device. Its metrological characteristic directly affects the accuracy of cigarettes’ draw resistance. Because different principles of micro-differential pressure sensors are used by each equipment manufacturer, the influences are not consistent on measuring the draw resistance. In order to study the influences of micro-differential pressure sensor on the draw resistance measurement, we will analyze its metrological characteristic through the acquisition of the output voltages under the different standard pressures. The experimental results show that the precision level of micro-differential pressure sensor using is higher, and it has little effect on the draw resistance measurement.
