Notes on using the transmitter
2011-9-15 17:29:24

    使用过程中的要点 变送器 在工艺管道上正确的安装位置与被测介质有关,为 获得最佳的测量 果,应注意考虑 以下 情况: The main points of the transmitter in use and the correct installation position of the transmitter on the process pipeline are related to the measured medium. In order to obtain the best measurement results , the following conditions should be considered :
1 . 过热的介质接触; Prevent the transmitter from coming into contact with corrosive or hot media;
2 . Prevent dross from depositing in the duct;
3 安装在温度波动小的地方; The impulse pipe should be installed in a place with small temperature fluctuations;

4 . 开在流程管道侧面, 这样可以 避免沉淀积渣。 When measuring the liquid pressure, the pressure tap should be opened on the side of the process pipeline to avoid sedimentation. 安装位置应 避免液体的冲击,以免传感器过压损坏。 The installation location of the transmitter should be protected from the impact of liquid to avoid damage to the sensor due to overpressure.

5 . 变送器 安装在流程管道 上部,以便积累的液体容易注入流程管道中。 When measuring the gas pressure, the pressure tap should be opened at the top of the process pipeline, and the transmitter should also be installed at the top of the process pipeline so that the accumulated liquid can be easily injected into the process pipeline.
    
6 . 其它高温介质时,需 接加缓冲管等冷凝器,不应 使变送器的工作温度超过极限。 When measuring steam or other high-temperature media, a condenser such as a buffer tube needs to be connected, and the operating temperature of the transmitter should not be exceeded.
7 . 装在室外的变送器必需 采取 相应的 防冻措施,避免引压口内的液体因结冰体积膨胀, 导致 传感器损坏。 When freezing occurs in winter, the transmitter installed outdoors must take corresponding anti-freezing measures to prevent the liquid in the pressure port from expanding due to the freezing volume, which will cause damage to the sensor.
 
8 . 绕性管并拧紧密封螺帽,以防雨水等通过电缆渗漏进变送器壳体内。 When wiring, pass the cable through the waterproof joint or flexible pipe and tighten the sealing nut to prevent rainwater and other leakage into the transmitter housing through the cable.
