As a representative model of the diffused silicon Hesman pressure sensor, the specification selection of the MBS1900-064G6601 pressure transmitter directly affects industrial measurement accuracy. This article provides an in-depth analysis of the technical parameters, specification differences, and purchasing considerations of this series of sensors, helping technical evaluators select the most suitable models such as AT-131 and DG1300 according to operating condition requirements, and solve the core issues of genuine product procurement and performance matching.

I. Technical Characteristics of Diffused Silicon Hesman Pressure Sensors

Diffused silicon Hesman pressure sensors are well known for their high accuracy, strong stability, and outstanding anti-interference capability. The MBS1900-064G6601 adopts monocrystalline silicon diffusion technology, with a measurement range covering 0~100MPa, an accuracy class up to 0.1%FS, and an operating temperature range of -40℃~125℃, fully meeting the requirements of harsh industrial field environments. Its core advantages lie in:

• Using imported original sensing elements, with long-term stability better than 0.2%FS/year
• All-stainless-steel welded structure, IP67 protection rating, with excellent vibration and shock resistance
• Compatible with multiple communication protocols such as HART and PROFIBUS-PA
• Certified by international standards such as CE, RoHS, and SIL2

II. Comparison of MBS1900 Series Specifications and Parameters

For different application scenarios, the MBS1900 series provides as many as 12 specification variants, and technical evaluators need to focus on the following differentiated parameters:

III. Selection Guide for Typical Application Scenarios

In the field of hydraulic system monitoring, the DG1300-BZ-B-2-0.2-CJ-AA model is recommended, with a dynamic response time of ＜5ms; for chemical process control, it is recommended to use PT124B-210-100MPa-M20, equipped with a Hastelloy diaphragm; while for the food and pharmaceutical industries, PMI009-732-350GB is more suitable, complying with FDA material certification. During technical evaluation, special attention should be paid to:

1. Whether the medium temperature exceeds the operating range of the sensor
2. On-site electromagnetic interference level and signal shielding requirements
3. Certification requirements for hazardous areas (such as ATEX and IECEx)
4. Long-term stability and calibration cycle requirements

IV. Genuine Product Procurement and Quality Verification

There are many imitations on the market claiming diffused silicon Hesman technology. As an authorized service provider in Northwest China, Xi'an Shenghongchuang Instrument Co., Ltd. provides the full range of products such as AT-131 and GT-V with factory traceability. Consumers can verify them through the following methods:

• Check the consistency between the laser-engraved serial number and the factory certificate
• Request third-party inspection reports (such as SGS material analysis)
• Measure whether the zero-point temperature drift is ≤±0.02%FS/℃
• Observe whether there is an original anti-counterfeiting mark at the pressure interface
