Product Details
Description:

I. Product Overview:

ZW3051LDP series single flange long-distance differential pressure transmitter is a new type of transmitter which imports advanced technology and equipment from abroad. The key raw materials, components and components are all imported. After rigorous assembly and testing, the whole machine has the characteristics of advanced design principle, complete varieties and specifications, simple installation and use. Because the appearance of the model fully integrates the structural advantages of two kinds of transmitters (Rosemount 3051 and Yokogawa EJA), which are popular and widely used in China at present, it gives users a refreshing feeling. At the same time, it can be directly replaced with traditional series products in installation, and has strong versatility and substitution ability.

II. Working Principle:

ZW3051LDP series single flange remote differential pressure transmitter is connected with stainless steel flange by capillary tube of 3051GP intelligent pressure transmitter. It is a kind of remote transmission device installed in pipeline or container to sense the measured pressure. The pressure is transferred to the main body of the transmitter by filling silicone oil (or other liquid) in capillary tube, and then transmitted by delta chamber and amplifying circuit in the main body of the transmitter. The board, which converts pressure or differential pressure to 4-20mA.DC signal, can communicate with each other, set and monitor with the hand-operated device in accordance with HART protocol.

3. Application occasions:

ZW3051LDP series single flange remote differential pressure transmitter is a pressure sensor assembly used to prevent the medium in the pipeline from entering the transmitter directly. It is connected with the transmitter by capillary filled with fluid. It is used to measure liquid level, flow rate and pressure of liquid, gas or steam, and then convert it into 4-20 mA DC signal output. The applicable media are as follows:

1. Viscous media at high temperature;

2. Easy to crystallize medium;

3. Precipitable media with solid particles or suspended solids;

4. Strong corrosive or highly toxic media;

5. It can eliminate the leakage of the guide pipe and pollute the surrounding environment, and avoid the tedious work of supplementing the isolation fluid because of the instability of the measurement signal when using the isolation fluid.

6. Continuous and accurate measurement of interface and density;

7. The remote transmission device can avoid the mixing of different instantaneous media, so that the measured results can truly reflect the actual situation of the process change.

8. occasions with high requirements for hygiene and cleanliness;

9. For example, in the production of food, beverage and medicine industries, not only the contact media parts of transmitters should meet the hygienic standards, but also they should be easy to rinse to prevent cross-contamination of different batches of media.

Fourth, main characteristics:

1. Simulate the "on-line operation" test step by step to ensure that the transmitter works steadily and reliably under the limit ambient temperature, medium temperature and working pressure (including positive pressure or vacuum).

2. The diaphragm will not be damaged after overloading and the precision will not change after long-term operation by using the "dynamic profile" remote transmission diaphragm structure.

3. Full fusion welding and rigid sealing filling system are selected to eliminate oil leakage.

4. Designing novel capillary bonding components to ensure the reliable protection of capillary, which is not easy to break in field use.

5. Various types, forms and sizes of remote transmission devices, as well as abundant types of filling liquid, can meet the measurement needs of various occasions.

6. Various products with special needs can be provided, including high temperature, high vacuum, fast response and long-distance pressure transmitters with unequal length capillaries (length less than 3 meters).
