Customized demand for diffused silicon Hirschmann pressure sensors is growing day by day, and the EJYB-GP-13 model, as a key component in the industrial field, has a customization process that directly affects equipment matching accuracy. This article, by the experts of Xi'an Shenghongchuang Instrumentation, provides an in-depth analysis of the entire process from model selection parameter confirmation to Hirschmann connector integration, covering technical comparisons of more than 10 models such as PT124B-210, helping you master the core customization points of diffused silicon sensors.

I. Definition and Technical Characteristics of Diffused Silicon Hirschmann Pressure Sensors

Diffused silicon Hirschmann pressure sensors use silicon piezoresistive sensing elements manufactured with MEMS technology, and achieve rapid signal transmission and protection through Hirschmann connectors. Their core advantages lie in the corrosion resistance of the 316L stainless steel diaphragm, as well as the wide range coverage of -0.1~100MPa. Taking domestic general-purpose pressure transmitter EET-1040 hydraulic oil pneumatic sensor as an example, its 0.1% high accuracy and 400℃ medium resistance make it particularly suitable for high-temperature and high-pressure scenarios such as metallurgy and electric power.

II. Analysis of the Full Customization Process for the EJYB-GP-13 Model

1. Parameter Confirmation Stage

It is necessary to clarify basic parameters such as pressure range (such as 1.6MPa or 2.5MPa), output signal (4-20mA/0-10V), and interface type (M20*1.5/G1/4). When comparing models such as PT124B-210 and SMP131-TLD, special attention should be paid to whether the medium temperature compensation range covers the working condition requirements of -20~85℃.

2. Key Points of Structural Customization

• Differences in mechanical strength between threaded mounting and flange mounting
• The dustproof and waterproof rating of the Hirschmann connector must reach IP67 or above
• Stability verification of aviation plug connection in vibration environments

III. Industry Application Scenarios and Technical Comparison

IV. Common Selection Misunderstandings and Solutions

Misunderstanding 1: Only focusing on nominal accuracy while ignoring temperature effects——in practical applications, it is necessary to confirm whether the compensated temperature range covers working condition fluctuations. For example, in chemical reactor scenarios, a model with 0.25% accuracy and a compensation range up to 150℃ should be selected.

Misunderstanding 2: Insufficient matching of interface specifications——although G1/2 and G1/4 interfaces are similar in size, the difference in sealing pressure rating can reach 2.5 times, and strict verification is required according to the DG1300-PJ-1-2-40-CJ-GK-GZ standard.
