Last week, a customer from Xi'an, Shaanxi purchased a batch of monocrystalline silicon pressure transmitters produced by the company. After the customer called to inquire, the company conducted an on-site inspection of the transmitter production workshop, exchanged product technical parameters, confirmed parameters, and signed a contract. Finally, when the customer received the goods, the company not only did not delay the customer's delivery time, but also delivered the prepared pressure transmitter products to the customer in advance through SF Express. When the customer received the goods and opened the pressure transmitter product packaging, each pressure transmitter was packaged in an independent cardboard box with pearl cotton packaging. The packaging details were very detailed, including the inner and outer packing lists, as well as the total shipping list. Each product had a barcode, which the customer traced with their phone. The relevant ordering information, the current opened pressure transmitter product code The specifications and other information can be directly seen, accurate and without error. The customer specially praised the quality of the monocrystalline silicon pressure transmitter produced by Jiangsu Runyi Instrument Co., Ltd!

The monocrystalline silicon pressure transmitter produced by the company has received high praise from customers! This is the strict quality control that the company has always maintained for its products.

The company's high-precision pressure transmitter digital workshop has intelligent AMR (AGV) mobile robot AGV, 1 set of intelligent kanban, intelligent storage cabinet (aging cabinet), mobile shelf type intelligent dense rack, left and right cycle automated control assembly production line, programmable constant temperature and humidity test box, programmable constant temperature and humidity test box, 4-axis fixed automatic screw locking machine, Vicat pressure controller, digital multimeter, fully automatic laser welding machine, fully automatic intelligent high vacuum flange oil injection intelligent equipment, etc. Using domestically produced equipment and a production execution system jointly developed with the North Jiangsu Research Institute of Shanghai Jiao Tong University, intelligent equipment is fully applied in the workshop, precise material distribution, real-time production process control, production information tracking and tracing, and internal and external linkage and collaboration in the workshop, achieving digital production.

The company's high-precision pressure transmitter adopts advanced MEMS technology to make monocrystalline silicon sensor chips. The monocrystalline silicon double beam suspension design achieves high accuracy, high overvoltage performance, excellent stability, and is embedded with intelligent signal processing modules to achieve excellent combination of static pressure and temperature compensation. It can provide measurement accuracy and long-term stability under large range of static pressure and temperature changes. It can be widely applied in various places.

At present, our company's high-precision pressure transmitter digital workshop has demonstrated and driven the level of intelligent manufacturing in 4 out of 5 production aspects, including planning and scheduling, production operations, quality control, warehousing and logistics, and equipment management, as well as in 9 out of 18 scenarios. At the same time, each of the three major supporting elements, equipment, network, and platform, covers at least one subcategory and has achieved certain construction results.

Firstly, the monocrystalline silicon pressure transmitter produced by the company has received high praise from customers! Progressiveness of intelligent storage test (aging) process:

The intelligent instrument testing system based on IoT cloud data processing applications mainly faces sensors. A qualified instrument often needs to undergo 48 hours or more of testing before leaving the factory. During this process, it is necessary to monitor the current fluctuation changes of the powered instrument and capture abnormal values of the current fluctuation. The feature of this system is that it can display real-time current fluctuation charts of multiple instruments, based on serial port reading of multiple instrument current signals. Divide this software into two functional modules: reading data and sending data, and finally classify and judge themAfter 48 hours of testing, the test level of the instrument is determined based on the current fluctuation of the instrument for 48 hours. The smaller the fluctuation, the lower the level, and the better the instrument performance.

Secondly, the monocrystalline silicon pressure transmitter produced by the company has received high praise from customers! Progressiveness of product temperature compensation process:

Set 5 temperature points in the automatic temperature compensation software system, -20 ℃, 0 ℃, 20 ℃, 40 ℃, and 70 ℃. Depending on the range range, set 9-11 pressure points to enter automatic temperature compensation. After a 15 hour cycle, download each temperature compensation data into the instrument. If the data is abnormal, this channel detection problem may occur. Conduct a precision test with both forward and reverse strokes, and maintain a temperature of 20 ℃. Give a rating judgment.

Thirdly, the monocrystalline silicon pressure transmitter produced by the company has received high praise from customers! The core film adopts advanced welding technology with a 1500 watt laser:

Our company adopts advanced fiber lasers, which represent the third-generation laser technology and have the advantages of other laser technologies. Fiber lasers have the advantages of ideal beam quality, ultra-high conversion efficiency, maintenance free, high stability, and small size. The laser is embedded in a dual swing laser welding head welding monitoring system, a red light positioning system, a welding system, a customized 6-axis linkage welding workbench, a 4-axis through-hole rotary table, a 5-axis welding fixture, etc., to ensure the welding sealing and stability of high-precision sensor membrane chips.

Fourthly, the monocrystalline silicon pressure transmitter produced by the company has received high praise from customers! Progressiveness of high precision air automatic oil injection process:

The progressiveness automatic oil injection process and the embedded control system ensure the accuracy of pressure and differential pressure transmitters and the long-term stability of 15 years.
