Notes on the use of differential pressure transmitters
2011-8-23 10:46:04

  微差压变送器 注意 事项 有以下几点 In daily use , the matters needing attention in the differential pressure transmitter are as follows :
微差压变送器 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; 1. When measuring differential pressure transmitter with steam or other high-temperature medium, its temperature should not exceed the limit temperature when the transmitter is used. If it is higher than the limit temperature used by the transmitter, it must use heat dissipation. Device
   差压变送器 测量蒸汽或 其他高温介质时,应 使用散热管, 要促 使 微差压变送器 和管道连在一起, 同时 使用管道上的压力传至变压器。 2. When measuring differential pressure transmitters with steam or other high temperature media, heat pipes should be used. The differential pressure transmitters should be connected to the pipeline, and the pressure on the pipeline should be used to transmit the voltage to the transformer. 当被测介质为水蒸气时,散热管中要注入适量的水, 用来 防过热蒸汽直接与变送器接触,损坏传感器; If the measured medium is water vapor, an appropriate amount of water must be injected into the heat pipe to prevent the superheated steam from directly contacting the transmitter and damaging the sensor

微差压变送器 在测量时,为防止 损伤传感器元件隔离膜片,导致变送器损坏,被测介质不允许结冰, 在使用时的 必要时需对变送器进行温度保护,以防 结冰; 3. When measuring the differential pressure transmitter , in order to prevent damage to the sensor element isolation diaphragm and cause damage to the transmitter, the measured medium is not allowed to freeze. When necessary, the transmitter must be temperature protected. To prevent icing;

不要 用硬物碰触膜片, 以防止 隔离膜片损坏; 4. Do not touch the diaphragm with hard objects to prevent damage to the isolation diaphragm;
不要 用高于36V 电压加到 微差压变送器 上, 以至 导致变送器损坏。 5. Do not use a voltage higher than 36V to the differential pressure transmitter , so as to cause damage to the transmitter.
