As a technical expert in the field of pressure measurement, have you ever been puzzled by the meaning of complex model codes such as PMP131-C1A2L16? This article provides an in-depth analysis of the model naming rules for diffused silicon pressure transmitters, helping you understand the key parameter information hidden in sensor suffixes, such as media type and measurement range, so that you can make precise selections.

I. Analysis of the Model Naming System for Diffused Silicon Pressure Transmitters

In the field of industrial automation, letter-number combinations that seem random, such as PMP131-C1A2L16, actually follow strict industry coding standards. Taking the DG1300-BZ-A-2-40/CJ/AM/FZ pressure transmitter produced by Xi'an Shenghongchuang Instrumentation Co., Ltd. as an example, its model structure can be broken down into the standardized format of "main model + parameter suffixes". Among them, "DG1300" represents the core series of diffused silicon sensors, "BZ" indicates the explosion-proof rating, "A-2" corresponds to the G1/4 threaded connection, "40" indicates the 0-40MPa range, while /CJ/AM/FZ correspond respectively to specially treated wetted materials, signal output type, and process connection method.

1.1 Decoding Key Suffix Parameters

By analyzing the naming patterns of models such as PT201H-G5000M and HM20-1-A1-F1-W2-T, three categories of core information can be summarized:

• Media Compatibility Identification: for example, "B29R" in PBM4-13.B29R represents a 316L stainless steel isolation diaphragm, suitable for corrosive liquids; while the suffix "R" in PA-21R-16 is specifically designed for food-grade media
• Range and Accuracy Codes: the JPB-CNM pressure transmitter manual shows that "M" in "CNM" represents an accuracy class of ±0.25%FS, and "N" indicates the standard range band of 0-1.6MPa
• Electrical Interface Specifications: the double "FU" in the MTPFU-MTPFU model indicates dual 4-20mA outputs, complying with the IEC 61508 functional safety standard

II. Selection Decision Matrix for Technical Evaluators

When faced with hundreds of variants such as PMP131-C1A2L16 and DG1300-BZ-A-2-2.5/AA/SZWZH, technical teams need to establish a systematic evaluation framework:

III. Technical Development Trends of Diffused Silicon Sensors

From the traditional PT201H-G5000M to the intelligent HM20-1-A1-F1-W2-T pressure transmitter, the industry is undergoing three major technological breakthroughs:

1)Upgraded Self-Diagnostic Function: the new PMP131-C1A2L16 series integrates ASIC chips, enabling real-time monitoring of sensor zero drift and sensitivity changes, meeting the predictive maintenance requirements of the VDMA 24400 standard

2)Wireless Integration: the latest DG1300-W series developed by Xi'an Shenghongchuang supports the WirelessHART protocol, reducing wiring costs by 90% in oil pipeline monitoring scenarios

3)Multi-Parameter Fusion: for example, the PA-21R-16 pressure transmitter has achieved synchronized temperature/pressure measurement, outputting compensated standard values through MODBUS RTU
