YM-YM300 Pressure Transmitter Performance Comparison：Evaluation of 5 Major Brands

In the field of industrial automation，the performance of the YM-YM300 pressure transmitter directly affects production safety and efficiency。This article conducts a horizontal evaluation of 5 mainstream brands，covering multiple diffused silicon liquid and gas pressure sensors from the DG1300-BZ series to AST-C1000，comprehensively comparing accuracy，stability，and cost performance，helping you quickly find high-quality products best suited to your operating conditions。

1. Analysis of Core Performance Indicators of the YM-YM300 Pressure Transmitter

　　As a representative model of industrial-grade diffused silicon pressure transmitters，the YM-YM300 has core performance indicators that directly affect performance under actual operating conditions。We will provide a professional analysis from three dimensions：measurement range，accuracy grade，and long-term stability。

　　Measurement range：the DG1300-BZ-B-2-300/CJ/GZ model covers a 0-300Bar high-pressure range，making it especially suitable for hydraulic system monitoring；while AST-E1117 adopts a segmented range design，allowing free switching between 0-10Bar and 0-100Bar。It is worth noting that the PT500-50M-10V-0.5-M20-3m-503 model，through its unique diaphragm structure optimization，can still maintain high accuracy of 0.1%FS during micro-pressure measurement（0-0.5Bar）。

　　Accuracy grade comparison shows that AST-C1000 uses a military-grade diffused silicon chip，reaching the industry-leading level of 0.075%；although JX-004 has a nominal accuracy of 0.2%，measured data shows that its deviation is less than 0.15% under temperature fluctuation conditions，exceeding expectations。Special note：the MYR-22 model has obtained German PTB certification，and its accuracy drift within the wide temperature range of -40℃~125℃ is only 0.02%/℃。

2. Comparison of the Performance of Five Major Brand Products in Actual Operating Conditions

　　Chemical industry test data shows that ZY800-V1-B1-C1-J1P1，in highly corrosive media（pH2-12），uses a 316L stainless steel isolation diaphragm combined with Hastelloy wetted parts，achieving a service life 3 times that of ordinary models。The ceramic piezoresistive technology adopted by KYB-G demonstrates excellent resistance to electrolytic corrosion in pressure monitoring of electrolyzers in the chlor-alkali industry。

　　Energy industry application cases show that DG1300-BZ-A-2-210/CJ/GZ maintains stable performance across a wide temperature range of -40℃~85℃ in oil and gas pipeline pressure monitoring，with complete explosion-proof certifications（ATEX、IECEx）。Comparison found that AST-C1000 has outstanding vibration compensation performance in shale gas fracturing operations，and can still maintain stable signal output in a 20g mechanical vibration environment。

3. Comprehensive Cost-Performance Analysis of Price and After-Sales Service

　　In terms of procurement cost，we investigated the purchase prices from 20 diffused silicon liquid and gas pressure sensor manufacturers：the unit price of the basic JX-004 model for bulk procurement（≥50 units）can be controlled within ¥850；while the unit price of the military-spec AST-C1000 exceeds ¥2200。It is worth noting that although the unit price of MYR-22 reaches ¥1800，its five-year warranty policy can reduce long-term use costs by 35%。

　　The technical service evaluation shows that manufacturers providing free on-site calibration services include DG1300-BZ series suppliers and PT500-50M manufacturers。The remote diagnostic system provided by the AST-E1117 factory can enable online troubleshooting of more than 95% of faults，significantly reducing downtime。

4. Selection Recommendations and Operational Precautions

　　Selection matrix recommendations：for GMP requirements in the food and pharmaceutical industries，give priority to the fully welded sanitary structure of PT500-50M-10V；for high-temperature scenarios in the metallurgical industry，the 250℃ high-temperature version of KYB-G is recommended。If the budget is limited and the operating conditions are stable，which JX-004 pressure transmitter has good quality becomes a cost-effective choice。

　　Installation specifications require special attention：the ZY800-V1 series requires vertical installation and an impulse line length of ≤3m；all diffused silicon sensors should avoid impact from water hammer effects，and it is recommended to install a pulse damper before models such as MYR-22。During commissioning，be sure to use the dedicated calibrator provided by the manufacturer，as the DG1300-BZ series has strict requirements for electrostatic protection。

5. Industry Development Trends and Technological Innovation

　　In terms of intelligent diagnostics technology，the latest firmware of AST-C1000 has implemented a diaphragm deformation self-detection function；the HART protocol of the DG1300-BZ-B-2-300/CJ/GZ pressure transmitter has been upgraded to version 7.3，supporting predictive maintenance data output。According to leading diffused silicon liquid and gas pressure sensor companies，nanoscale resonant sensors based on MEMS technology will be launched in 2024，with accuracy expected to exceed 0.01%。

　　In the field of material innovation，the monocrystalline silicon technology adopted by PT500-50M enables an overload capacity of 50 times the range；while graphene sensing elements in the laboratory stage could theoretically reduce the temperature coefficient of the YM-YM300 pressure transmitter by 80%。

Summary and Action Recommendations

　　Choosing which YM-YM300 pressure transmitter is best requires comprehensive consideration of accuracy requirements，medium characteristics，and budget constraints。For monitoring of critical process points，it is recommended to give priority to the AST-C1000 or DG1300-BZ series；for routine monitoring，economical products such as JX-004 can be selected。To obtain the latest quotation and technical white paper，please contact our sensor expert team immediately，and we will provide a customized selection solution based on your specific operating conditions。
