Intelligent remote differential pressure transmitter in order to adapt to different needs, SC3051DP remote pressure transmitter has a variety of forms of remote transmission device mode, the main structure is the same as the differential pressure transmitter, widely used in petroleum, chemical, electric power, food, paper, municipal engineering and other industries. When the differential pressure transmitter and the measured equipment with a capillary connection between the differential pressure transmitter with remote transmission, that is to become a differential pressure transmitter, is a kind of installed in the pipeline or container on the remote transmission device to feel the measured pressure, the pressure by the capillary tube filled with silicone oil (or other liquids) to the transmitter body, and then by the transmitter body of the δ room and amplification circuit boards, will be the pressure or differential pressure converted to 4-20mA.DC signal output, and the operator in line with the HART protocol, the transmitter can be used to control the pressure, the pressure, the pressure and the pressure, and the pressure. DC signal output, and with the HART protocol hand manipulator, can communicate with each other for setting and monitoring.
Intelligent remote differential pressure transmitter applicable occasions:
1, high temperature viscous media
2, easy to crystallize the medium
3, with solid particles or suspended sedimentary media
4, strong corrosion or toxicity of the medium
5, can eliminate the leakage of the pressure conduit pollution of the surrounding environment occurs; can eliminate the use of isolation fluid, due to the instability of the measurement signal, the need for frequent replenishment of the isolation fluid of the cumbersome work.
6、Continuous measurement of interface and density
7、The remote transmission device can avoid the cross-mixing of different instantaneous media, so that the measurement results truly reflect the actual situation of the process changes.
8、Health and cleanliness requirements are very high occasions
9, such as food, beverage and pharmaceutical industry production, not only requires the transmitter contact media parts in line with health standards, and should be easy to flush to prevent cross-contamination of different batches of media.
Intelligent remote differential pressure transmitter features :
1, each simulation “online operation” assessment, to ensure that the transmitter in the limit of ambient temperature, medium temperature and working pressure (including positive pressure or vacuum), stable and reliable work.
2、Using “dynamic type surface” remote transmission diaphragm structure, the diaphragm will not be damaged after overloading; the accuracy will not change after long-term work.
3、The filling system adopts full welding and rigid sealing structure, which eliminates the occurrence of oil leakage.
4、Novelly designed capillary tube combined parts, so that the capillary tube is reliably protected, and is not easy to break in the field.
5, varieties, forms and sizes of telemetry devices, as well as a rich variety of filling liquid, can meet the measurement needs of different occasions.
6, can provide a variety of special needs products, including high temperature, high vacuum, fast response and unequal length capillary (difference ≤ 4.5 meters) remote differential pressure transmitter.

Note:
① The static pressure of the remote pressure transmitter also depends on the specification of the selected flange.
② The working temperature of the remote device is determined by the type of filling liquid selected.
③ The medium temperature effect of the remote differential pressure transmitter is the output change of the remote device on both sides, which is subjected to the same temperature at the same time from the room temperature.
④ Static pressure and temperature influence are measured at the maximum range.
⑤ The maximum length of capillary tube on both sides of DP type remote differential pressure transmitter is 7.5 meters, and the length difference between both sides is 4.5 meters.
