不要在 变送器 上用高于36V 电压, 否则容易 导致变送器损坏; 1. Do not use a voltage higher than 36V on the transmitter , otherwise the transmitter may be easily damaged;
膜片 不要让 硬物碰触, 否则容易 导致隔离膜片损坏; 2. Do not let hard objects touch the diaphragm , otherwise it will easily cause damage to the isolation diaphragm;
被测介质不 可以 结冰, 要不然 将损 传感器元件隔离膜片, 容易 导致变送器损坏 ;因此在 必要 对变送器进行温度保护,以防 结冰; 3 , the measured medium must not be frozen, otherwise the sensor element isolation diaphragm will be damaged , which will easily cause the transmitter to be damaged ; therefore, when necessary , the transmitter needs to be temperature protected to prevent freezing;
在测量蒸汽或 其他高温介质时, 它的 温度不应 超过变送器使用时的极限温度, 如果 高于变送器使用的极限温度 那么就 必须使用散热装置; 4. When measuring steam or other high-temperature media, its temperature should not exceed the limit temperature of the transmitter . If it is higher than the limit temperature of the transmitter, then a heat sink must be used;
测量蒸汽或 其他高温介质时,应 使用散热管,使 变送器 和管道连在一起,并 可以 使用管道上的压力传至变压器。 5. When measuring steam or other high-temperature media, a heat pipe should be used so that the transmitter and the pipe are connected together, and the pressure on the pipe can be used to transmit to the transformer. 被测介质为水蒸气时, 那么 散热管中 必须 要注入适量的水, 以防 过热蒸汽与变送器直接接触, 从而 损坏传感器; If the measured medium is water vapor, the heat pipe must be filled with an appropriate amount of water to prevent direct contact between the superheated steam and the transmitter, thereby damaging the sensor;
在压力传输过程中,应注意以下 6. In the process of pressure transmission, the following three points should be noted :
   1 变送器 与散热管 连接处, 不应该有 漏气 现象 ( 1 ) There should be no air leakage at the connection between the transmitter and the heat pipe ;
   2 如果在开始 使用前,阀门是关闭的, 那么在 使用时,应该 非常小心缓慢地打开阀门,以 防止 被测介质直接冲击传感器膜片,从而损坏传感器膜片; ( 2 ) If the valve is closed before use, the valve should be opened very carefully and slowly during use to prevent the measured medium from directly impacting the sensor diaphragm, thereby damaging the sensor diaphragm;
   3 、必须保持管路畅通, 如果 管道中的沉积物弹出, 损坏传感器膜片。 ( 3 ) The pipeline must be kept clear. If the sediment in the pipeline is ejected, the sensor diaphragm will be damaged.
