2023 Core Guide for Purchasing Industrial Pressure Transmitters

In the field of industrial automation，the MYR-22 pressure transmitter is a critical measuring device，and its performance and price directly affect production efficiency. This article addresses the key purchasing pain points of diffused silicon liquid and gas pressure sensors，providing an in-depth analysis of the cost-performance advantages of popular models such as DG1300-BZ and AST-E1117，helping operators quickly identify high-quality suppliers. From factory direct procurement to quality comparison，the latest 2023 purchasing guide reveals which pressure transmitter truly delivers outstanding value for money.

I、Technical Analysis of Diffused Silicon Pressure Transmitters

Diffused silicon technology，thanks to its excellent stability and accuracy，has become the preferred solution for industrial pressure measurement. Taking the DG1300-BZ-B-2-300/CJ/GZ model as an example，it adopts the monocrystalline silicon piezoresistive effect principle，with a measuring range of 0-300bar and a temperature compensation range of -40℃~125℃，fully meeting the requirements of harsh environments such as petrochemical and water treatment applications. The AST-E1117 series uses laser trimming technology to control nonlinearity error within ±0.1%FS，making it particularly suitable for precision application scenarios such as medical equipment. Operators should focus on the long-term stability indicators of sensors. For high-quality products such as PT500-50M-10V-0.5-M20-3m-503，the annual drift is usually ＜0.2%/year，which can significantly reduce calibration and maintenance frequency.

III、Key Factors in Purchasing Decisions

Price is not the only factor to consider. Operators should establish a multidimensional evaluation system：First，verify whether the manufacturer has ISO9001 quality management system certification. For example，AST-C1000 pressure transmitter manufacturers usually hold SIL2 functional safety certification；Second，compare output signal types. Models such as ZY800-V1-B1-C1-J1P1 support dual outputs of 4-20mA/RS485，which cost 15%-20% more than a single signal interface but significantly improve system compatibility. For projects with limited budgets，the KYB-G series can reduce costs by 30% by simplifying the housing material，while the core sensing elements still maintain imported quality. Special reminder：Low-cost products such as JX-004 may use ordinary silicon instead of diffused silicon，which can be verified through infrared spectroscopy testing.

IV、Recommendations for Matching Industry Application Scenarios

Different operating conditions have different requirements for sensors：In the food and pharmaceutical industries，the YM-YM300 pressure transmitter has become the preferred choice due to its 316L fully welded structure and EC1935/2004 food-grade certification；while the construction machinery sector places more emphasis on the vibration resistance of DG1300-BZ-A-2-210/CJ/GZ（up to 50g impact acceleration）. For high-temperature steam measurement，the PT500 series with heat sinks should be selected，as its internally integrated temperature compensation algorithm can effectively suppress thermal zero drift. Experience shows that proper model selection can extend sensor service life by 3-5 times. After a chemical plant replaced a standard model with AST-E1117，annual maintenance costs were reduced by 42%.

V、Clarification of Common Purchasing Misconceptions

• Misconception 1：Imported brands are always superior to domestic brands - Actual test data shows that high-end domestic models such as ZY800-V1 have surpassed some international brands in stability at -30℃ low temperatures
• Misconception 2：The larger the measuring range，the better - A 20% margin should be reserved when selecting the measuring range. The accuracy of DG1300-BZ-B-2-300 under 150bar operating conditions is 0.3 grade higher than at the full range of 300bar
• Misconception 3：Ignoring the impact of installation method
