BLD3351SDP/GP 远传差压/ 压力变送器
BLD3351SDP/GP 变送器带上远传密封装置后，就成为BLD3351SDP/GP 远传差压/ 压力变送器。
BLD3351SDP/GP远传差压/压力变送器，可避免被测介质直接和变送器的隔离膜片接触，它适用于下面几种情况：
1. 被测介质对变送器接头和敏感元件有腐蚀作用时；
2. 需要将高温被测介质与变送器隔离时；
3. 被测介质中有固体悬浮物或高粘度易堵塞变送器接头和压力容室时；
4. 被测介质用引压管引出易固化或结晶时；
5. 更换被测介质需要冲洗而不用交混时；
6. 必须保持卫生条件，防止污染时。
BLD3351SDP/GP型带远传密封装置的远传差压/ 压力变送器，仍具有BLD3351SDP/GP差压/ 压力变送器的各种特点。提供多种结构材料，远传装置组件焊接结构，可靠性强。充液腔低容积设计，减少温度影响，根据用户要求内充DC200系列硅油使用温度-40~+149℃；高温硅油使用温度-15~315℃。远传装置工作压力上限是用户选择远传装置的额定值；工作压力不低于3.5Kpa(绝对压力)。对腐蚀介质的选择隔离膜片材料参见附表，仅作用户选型时参考。
BLD3351SDP/GP if the transducer with Remote transmission device，it will be BLD3351SDP/GP Remote transmission Remote transmission device. BLD3351SDP/GP Remote transmission differential/pressure transducer can avoid the medium contact the diaphragm directly , it apply for the following situation：
1. if the medium is corrosive；
2. if the medium is high temperature；
3. if the medium contain float solid or viscosity；
4. if the medium easy to became solid or crystallize；
5. if need to be clean and avoid pollution;
BLD3351SDP/GP Remote transmission device，it still has feature of BLD3351SDP/GP differential/pressure transducer. We can supply variety material，Remote transmission device welding structure，with high reliability. Low volume design，reduce temperature influence. According to customer request, we can supply filling DC200silicon, working temperature is -40~+149℃；high temperature silicon is -15~315℃。
Working pressure of emote transmission device if the rating that customer chose；Working pressure will be not lower than 3.5KPA(absolute pressure), for your reference.
