- 摘要:
- 差压式流速传感器因工作稳定可靠、成本低而广泛应用于各类矿山、巷道的气体流速监测，该文通过分析传统S型皮托管测量气体流速的原理及使用局限性，详细介绍了一种基于自导流S型皮托管的新型差压流速传感器的结构特点及传感器软、硬件设计，将差压式流速传感器测量下限提高到0.15 m/s，满足了《煤矿安全规程》对煤矿巷道最低风速监测的规定。在实验室完成了性能测试，试验结果表明传感器在-20～50 ℃范围内和煤泥附着的情况下基本误差均满足行业标准要求。
- Abstract:
- Differential pressure flow velocity sensors are widely used in various mines and roadways due to their stable and reliable operation and low cost. This article analyzes the principle and limitations of traditional S-type pitot tubes for measuring gas flow velocity, and introduces in detail the structural characteristics and sensor software and hardware design of a new type of differential pressure flow velocity sensor based on self guided S-type pitot tubes. The lower measurement limit of the differential pressure flow velocity sensor is increased to 0.15 m/s, It meets the requirements of "Coal Mine Safety Regulations" for monitoring the minimum wind speed in coal mine tunnels. Performance testing has been completed in the laboratory, and the test results show that the sensor’s basic error meets the requirements of industry standards within the range of - 20 to 50 ℃ and with coal slime adhesion.
