该气压计是冶金部安全技术研究所在WFQ—1型防爆数字式气压计的基础上经改进研制而成的。它适用于煤矿及金属矿快速测定井巷通风阻力,既能测量气压差,又能测量大气压力。现场使用表明,它具有灵敏度与测量精度高、携带方便、操作简单、比 WFQ—1型使用范围宽、 适用于深井、降低电源电压和简化电路与结构等优点。文中介绍了该气压计的结构原理、技术性能和使用效果。
The barometer is the Ministry of Metallurgical Safety Institute developed in the WFQ-1 explosion-proof digital barometer developed from improved. It is suitable for rapid determination of mine roadway ventilation resistance in coal mines and metal mines, both to measure the pressure difference, but also to measure atmospheric pressure. Field use shows that it has the advantages of high sensitivity and measurement accuracy, easy to carry, easy to operate, wider range of applications than WFQ-1, suitable for deep wells, power supply voltage reduction and simplification of circuits and structures. The paper introduces the structure of the barometer principle, technical performance and the use of results.
