 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Demonstration of a Gas-Sensing Application for a Gas Switch Device Using the LabVIEW-Based Measurement System) ผู้เขียน:Thongchai Panmatarith สื่อสิ่งพิมพ์:pdf AbstractA standard ceramic method was used to prepare ZnO+0.01Sb2O3 ceramics. The measurements and processing of the data were made using: an LP connector, a data acquisition card, a computer and the LabVIEW program. The gas-response characteristics of the sample to NH3 vapor were investigated. Result showed that the resistance of the sample at room temperature decreased in the interval of 4.4 M? –3.7 MW in the presence of NH3 gas at 30?C in normal atmospheric conditions. NH3 gas responsivity (G) was -15.909%. The result indicated a potential application in a low-cost NH3 gas switch device. The application of ZnO+0.01Sb2O3 gas ceramics as an NH3 gas switch device was investigated at room temperature. The results showed that the voltage drop across the sample decreased in the presence of NH3 gas. The operation as an NH3 gas switch device used the comparison of the voltage drop across the sample with a setpoint voltage (2.03 V). This result controlled the operation of a relay, solid state relay and gas alarm, respectively. It showed that the sample could be used as an NH3 gas switch. The system has been in operation for a year and all components have functioned well. |
