In the field of industrial automation, the price of the BP-BP200 pressure transmitter and the cost control of diffused silicon sensors have always been the focus of attention for technical evaluators and corporate decision-makers. As a high-tech enterprise in Xixian New Area, Xi'an Shenghongchuang Instrumentation Co., Ltd. will reveal to you how to effectively reduce costs while ensuring the accuracy of products such as ST-ST950 and HR-M2 by optimizing the materials and processes of diffused silicon sensors.

Cost Composition and Optimization Strategies for Diffused Silicon Sensors

The core cost of diffused silicon pressure sensors mainly comes from three parts: silicon wafer materials, packaging processes, and signal conditioning circuits. Taking the BP-BP200 pressure transmitter as an example, the diffused silicon technology it uses forms strain resistors on a monocrystalline silicon wafer through an ion implantation process. Compared with traditional metal strain gauge sensors, the material cost is reduced by more than 30%. Through its self-developed wafer cutting technology, Xi'an Shenghongchuang has increased wafer utilization to 92%. Combined with automated SMT equipment, this reduces the unit production cost of models such as CY-CY3018 by 15%-20%.

Industry Application Scenarios and Comparative Performance Analysis

In the petrochemical field, the diffused silicon sensor used in the HT-805 pressure transmitter demonstrates significant advantages: its measurement accuracy reaches ±0.1%FS, and its long-term stability is better than 0.2%/year, far superior to ceramic capacitive sensors. When used together with the domestic electromagnetic flowmeter 93636-135 pipeline-type intelligent electromagnetic flowmeter, it can build a complete fluid monitoring system. This system supports the MODBUS protocol and enables synchronized acquisition of pressure and flow data. Compared with other types of sensors, the diffused silicon solution offers better cost performance in the following scenarios: measurement of highly corrosive media (such as model SP-802), and high-frequency dynamic pressure detection (such as the CHR-CHR3000 series).

Key Technical Parameters and Procurement Decision Points

When selecting a model, technical evaluators should focus on three core parameters:

• Temperature compensation range: high-quality diffused silicon sensors (such as DG-DG1210) should have wide-temperature-zone compensation capability of -40℃~125℃
• Overload protection factor: the HR-M2 series has a calibrated value of 300%FS, significantly reducing on-site failure rates
• Media compatibility: model CHR-CHR306 uses a 316L stainless steel isolation diaphragm, capable of withstanding corrosive liquids with pH2-11

Common Technical Misconceptions and Solutions

Many users believe that diffused silicon sensors (such as ST-ST950) are not suitable for vibration environments, but this is actually a misunderstanding. By improving the sensor packaging structure and adopting three-dimensional stress isolation technology, Xi'an Shenghongchuang enables the product to maintain Class 0.25 accuracy even under a vibration acceleration of 15g. Another common issue is diaphragm damage caused by media crystallization. Our model SP-802 innovatively uses a nano oil-repellent coating, reducing crystal adhesion by 70%.
