单杠杆的气动靶式流量变送器主要用来连续测量工业生产过程中的液体的流量.它不需要孔板之类的节流装置,直接安装在通过流体的管道之间.因此,其结构简单、造价低,可以连续测量粘度较大,有微小颗粒、易结晶、易沉淀的介质液体. 1.检查 (1)查压力表.在调板变送器以前,首先检查显示输出压力值的标准压力表是否泄漏.挤压洗耳球,加压于压力表(0～1.6 kgf/cm~2),如图所示,使压力上升到1kgf/cm~2,然后用血管钳卡住橡胶管,观察十分
Single lever pneumatic target flow transmitter is mainly used to continuously measure the flow of liquid in industrial production process.It does not require orifice devices such as throttling device, directly installed in the pipeline through the fluid.Therefore, the structure Simple, low cost, continuous measurement of the viscosity of the larger, small particles, easy to crystallize, easy to sediment medium liquid 1. Check (1) Check the pressure gauge In the modulation transmitter, first check the output pressure Pressure gauge (0 ~ 1.6 kgf / cm ~ 2), as shown in the figure, make the pressure rise to 1kgf / cm ~ 2, and then use a forceps to clamp the rubber Tube, observe very
