[China Instrument Network Instrument R&D] A few days ago, the “PDS High-precision (0.04) Smart Pressure Transmitter†project undertaken by Chongqing Silian Measurement & Control Technology Co., Ltd. passed the review and acceptance by experts from the Chongqing Economic and Credit Commission.
At the review meeting, the project leader Nie Shaozhong gave a report and demonstration on the project's working ideas, organization and implementation, and major achievements. It introduced in detail the innovative R&D of 0.04 class intelligent pressure transmitters in sensors, circuits, and structures. The sensor has been completely redesigned from principles, materials, and structures. The circuit part also draws lessons from early products, and realizes new design ideas such as circuit universalization, communication modularization, and compensation specialization. At the same time, it has developed new ones. Process equipment and manufacturing technology.
After the report was completed, members of the review team visited the manufacturing site and product display area. They highly evaluated the successful implementation of the project and the results achieved. The evaluation team members stated that: The quadruple measurement and control accuracy of this high-precision pressure transmitter The technical indicators such as grade and stability meet or exceed the world-class pressure transmitter research and development companies, and have completed the assessment indicators specified in the contract, unanimously agreed to pass the acceptance.
It is reported that PDS high-precision (0.04) smart pressure transmitter as a newly launched product, all aspects of performance have reached the international advanced level, the current test is basically completed and formed a full range of products. The successful acceptance of this project has further improved the technical indicators of the product and will further increase the competitiveness and popularity of Sichuan Instrument in the industry.

Cold Drawn Steel Bar
Cold drawn steel bar is produced by Hot Rolled Steel Bar or wire rod to get smooth surface, more precision size, higher mechanical properties, which improves machining characteristics. It can also get various sections and sizes. So cold drawn steel bar is a better choice for machining users.
For high carbon steel or alloy steel bars, to avoid the cracks in inner or surface, the bars are usually required to be annealed before cold drawing.
To get different mechanical properties or hardness depending on final usage, the cold drawn bars will also be heat treated such as annealed, normalized or quenched and tempered(Q&T).
For CNC machines usage, to get much more precision sizes or much more better surface roughness for chrome plating, the cold drawn steel bars can also be centerless ground or polished.
We have more advantages on producing cold drawn steel bars:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Wide range of cold drawn steel bar sizes: from 10mm to 150mm
3) Different cold drawing medias powder or oil to get different surface
4) Straightening machines to get better straightness up to 0.5mm/m
5) Grinding and polishing machines to get better roughness upto 0.4um
6) Heat treating furnaces to adjust the mechanical properties
7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
8) Multiple packages to avoid broken packages and anti-rusty
