Double flange differential pressure transmitter
First, the product introduction
The double flange remote differential pressure and pressure transmitter need to be installed on the pipeline or the container to sense the measured pressure. The pressure is transmitted to the body of the transmitter through the capillary filling silicone oil (or other liquid), and then transmitted by the transmitter. The chamber and the line amplifier board in the main body of the device convert the differential pressure and pressure into 4-20 mA·DC.
The double flange remote transmission differential pressure, pressure transmitter and intelligent amplification board can form a smart remote differential pressure and pressure transmitter, which can communicate with the handheld communicator for setting and monitoring.
In order to meet different requirements, the transmitters of this series have various forms for users to choose. The main structure of the transmitter is the same as the differential pressure and pressure transmitter.
Second, the double flange transmitter is mainly used for the following occasions measurement
1. Viscous medium at high temperature;
2. A medium that is easy to crystallize;
3. A precipitation medium with solid particles or suspended matter;
4. Strong corrosive or highly toxic medium;
5. It can eliminate the occurrence of surrounding environmental pollution caused by leakage of the pressure guiding tube; when the isolation liquid is used, the cumbersome work of replenishing the isolation liquid is often required due to the instability of the measurement signal;
6. Continuously and accurately measure the interface and density. The remote transmission device can avoid the mixing of different instantaneous media, so that the measurement results truly reflect the actual situation of the process change;
7. Occasionally, the requirements for hygienic cleaning are high;
For example, in the production of food, beverage and pharmaceutical industries, it is not only required that the transmitter contacts the medium to meet sanitary standards, but also should be easily rinsed to prevent cross-contamination of different batches of media;
Third, technical parameters and performance
Note; The static pressure of the remote pressure transmitter and the working pressure of the remote pressure transmitter also depend on the specifications of the selected flange.
The operating temperature of the remote transmission device is determined by the type of filling liquid selected.
The influence of the medium temperature of the remote transmission transmitter is that the remote transmission devices on both sides are subjected to the same temperature at the same time, and the output changes are generated. The remote transmission pressure transmitter refers to the remote transmission device on one side. The effect of temperature on the output changes produced.
The effects of static pressure and temperature are measured at the maximum range.
最大 DP type remote transmission differential pressure transmitter on both sides of the maximum length of 7.5 meters, the length difference between the two sides is 4.5 meters; GP type remote transmission pressure transmitter side capillary length is generally 1.5 meters, the longest should not exceed 3 meters (Special agreement on the situation of the Pearl)
