How to Identify Genuine Original FG-FG500 Pressure Transmitters? A Comprehensive Anti-Counterfeiting Analysis of Diffused Silicon Sensors

When purchasing an FG-FG500 pressure transmitter, how can you ensure that you are buying a genuine original diffused silicon sensor? As a professional flow control equipment manufacturer, Xi'an Shenghongchuang Instrumentation Co., Ltd. reveals anti-counterfeiting tips for diffused silicon sensors to help you identify the authenticity of products in the PT-A, SWT131 and other series, and avoid procurement risks.

I. Key Identification Features of Genuine Original Products

The genuine FG-FG500 pressure transmitter uses a high-precision diffused silicon sensor, and its core identification features include:

• Laser-engraved markings: Original products use laser engraving technology on both the sensor housing and the circuit board, with clear lettering and no burrs, while counterfeit and inferior products mostly use inkjet coding or screen printing
• Unique serial number: Each genuine sensor has an independent identity code, which can be verified through the manufacturer's official website or 400 hotline
• Process details: Original factory solder joints are even and full, and the seals are made of fluororubber material, while imitations often have issues such as rough solder joints and poor-quality sealing materials

It is worth noting that these identification standards also apply to PT-A pressure transmitters and the SWT131 series. When verifying the measurement range, the range error of a genuine CYB-28 pressure transmitter should be ≤±0.1%FS.

II. Professional Testing Methods and Tools

For industrial users, we recommend the following professional verification methods:

For scenarios requiring the measurement of highly corrosive media, it is recommended to use it together with the Domestic Electromagnetic Flowmeter CGRD Pipeline Intelligent Electromagnetic Flowmeter, whose fully digital processing technology and corrosion resistance can form a complete monitoring solution together with the pressure transmitter.

III. Inspection of Supporting Equipment and Certification Documents

A complete original factory package should include:

1. Factory inspection report for QYB101 supporting equipment (including metrology certification number)
2. List of dedicated accessories for SNYB810 and anti-counterfeiting labels
3. Communication protocol instructions for PLS series supporting instruments (HART/MODBUS)
4. Product warranty card and after-sales service commitment letter

Special reminder: The wiring diagram of the genuine CYB-23 pressure transmitter is printed on anti-counterfeiting watermark paper, and there is a color-shifting anti-counterfeiting mark in the lower right corner of the drawing. In contrast, imitations often use ordinary copy paper, and the circuit markings are blurred and unclear.

IV. Verification of Manufacturer Direct Sales Channels

To avoid the risk of repackaging by intermediaries, it is recommended to purchase through the following methods:

• Directly contact the official sales department of Xi'an Shenghongchuang Instrumentation Co., Ltd.
• Check the supplier's manufacturer authorization certificate (within the validity period)
• Request the original factory inspection records from the most recent 3 months
• Verify the consistency between the logistics code on the product outer packaging and the delivery note

For precision instruments such as FG-FG500, direct supply from the original factory ensures complete after-sales support, including free calibration services and lifetime technical consulting.

Professional Purchasing Recommendations and Industry Applications

Based on our 15 years of industry experience, different operating conditions should be matched with suitable sensor types:

• Petrochemical industry: It is recommended to select the PLS series with anti-corrosion coating, combined with the intelligent electromagnetic flowmeter to achieve dual-parameter monitoring of acid and alkali media
• Water conservancy engineering: The SNYB810 series with IP68 protection rating is recommended, suitable for long-term operation at 10 meters underwater
• Food and pharmaceuticals: The TS-802 stainless steel sealed model certified by FDA must be selected

When verifying the accuracy of the PT-A pressure transmitter, operation must be carried out in accordance with the JJG 882-2019 verification regulation, using a 0.05-grade standard pressure generator for full-range testing.
