DG1300-BZ-A-2-210 Pressure Transmitter：How to Identify Genuine and Counterfeit Products？

In the field of industrial automation，the authenticity identification of the DG1300-BZ-A-2-210 pressure transmitter is directly related to production safety and measurement accuracy。Faced with price differences among many brands of diffused silicon pressure sensors on the market，such as AST-E1117，PT500，etc.，how can you ensure that you purchase genuine products？This article will reveal key identification techniques for operators，helping you avoid the trap of inferior products。

I、Core Parameter Comparison：Differences Between Genuine Products and Imitations

A genuine DG1300-BZ-A-2-210 pressure transmitter uses a military-grade diffused silicon core，with range error controlled within ±0.1%FS，while imitations often use low-cost ceramic sensors，and the error may be as high as ±1.5%。The following comparison table can help quickly identify key differences：

II、Four-Step Physical Identification Method

Step 1: check the housing material：genuine products are integrally cast from 316L stainless steel，weighing 15%-20% more than imitations，and the surface has a laser-engraved unique serial number。Step 2: observe the cable interface：the waterproof connector supplied by the original manufacturer usually has an embossed brand LOGO，while counterfeit products mostly use generic connectors。Step 3: test the button feel：the adjustment buttons of genuine products have a clear tactile step feel，while the buttons of imitations are loose and prone to jamming。Step 4: verify the protection rating：genuine IP68 protection can operate continuously at 2 meters underwater，while imitations usually show abnormal display after being immersed for 30 minutes。

III、Factory Traceability and Qualification Verification

Regular manufacturers，such as AST-C1000 pressure transmitter manufacturers，all provide verifiable ISO 9001 quality management system certificates。Operators are advised to：1) request the original factory inspection report（including pressure cycle test curves）；2) check whether the anti-counterfeiting QR code links to the official website database；3) require the supplier to provide at least 3 similar project cases（such as PT500-50M application cases in the petrochemical industry）。Special note：special models such as DG1300-BZ-A-2-210/CJ/GZ should have corresponding explosion-proof certification documents（Ex d IIC T6）。

IV、Analysis of Typical Application Scenarios

In hydraulic system monitoring，genuine DG1300 series products can achieve 2 million pressure cycles without failure，while imitations show zero drift after only 200,000 cycles。A certain oilfield case shows that the use of counterfeit KYB-G pressure transmitters led to false alarms of water injection pressure，causing more than one million yuan in maintenance losses each year。By comparison，choosing products certified to API 6A，such as ZY800-V1-B1-C1-J1P1，can ensure reliable operation in high-pressure wellhead environments。

V、Procurement Pitfall Avoidance Guide

1. Price warning：when the quotation for the MYR-22 pressure transmitter is 30% lower than the market average price，high vigilance is required；2. Channel verification：the list of authorized distributors should be published on the official website；3. Testing requirements：conduct a 5-point calibration test immediately after receipt（0%，25%，50%，75%，100% of range）；4. Warranty terms：genuine products usually provide a 36-month warranty，while imitations often provide only 6-12 months。For popular models such as JX-004，it is recommended to test samples for HART communication protocol compatibility before bulk purchasing。

VI、Industry Trends and Technological Evolution

With the popularization of IIoT technology，new-generation pressure transmitters such as YM-YM300 have begun to integrate wireless transmission modules（supporting the LoRaWAN protocol）。However，it is worth noting that 60% of the "smart" imitations on the market actually use the 2.4GHz non-standard frequency band，posing a serious risk of interference。It is recommended to choose products certified by WirelessHART to ensure seamless integration with existing DCS systems。
