Analysis of Diffused Silicon Hesseman Pressure Sensor Technology

As a core component in the field of industrial automation, the MT-MT208 pressure transmitter adopts diffused silicon Hesseman sensor technology to achieve high-precision pressure detection through the semiconductor piezoresistive effect. Its core advantage lies in the combination of 316 stainless steel material and laser marking process, enabling it to withstand a medium temperature range of -30～+85℃ while still maintaining a stability of ±0.1％FS／year in harsh environments such as hydraulic control and petrochemicals. Relying on the high-tech industrial advantages of Xixian New Area, Xi'an Shenghongchuang Instrumentation Co., Ltd. applies this technology to series products such as Domestic High-temperature Pressure Transmitter PT124B-285 Diffused Silicon 2088 Pressure Sensor, meeting the requirements of the ISO 9001 quality management system.

Typical Application Scenarios and Performance Comparison

In power station operation inspection scenarios, the MT-MT208 pressure transmitter has obvious advantages over traditional piezoelectric sensors: its 4～20mA output signal has stronger anti-interference capability, and the rise time of ≤5 milliseconds enables rapid response to sudden pressure changes. Actual test data shows that within the 0～250MPa range, the 0.25 accuracy class of this model is on average 15% higher than similar products. For dynamic pressure monitoring requirements such as locomotive braking systems, the differential amplifier circuit equipped in the product can effectively eliminate common-mode interference, which creates a significant difference from basic models such as MB-MB320.

Selection Guide and Industry Certifications

When purchasing a pressure transmitter, three dimensions should be重点 considered: first is the interface standard, and the MT-MT208 provides multiple thread options such as M20×1.5 and G1/4; second is the certification system, as this product has passed international certifications such as CE and RoHS; finally, expansion functions should be considered, such as an optional LCD display head for local monitoring. For users of constant-pressure water supply systems, it is recommended to choose models with zero point/full scale adjustment functions, which are more flexible compared with fixed-range products such as PB-CNM.

Analysis of Common Operating Misconceptions

• Misconception 1: Assuming all diffused silicon sensors have the same performance——in fact, the signal-to-noise ratio of the Hesseman technical solution is improved by 30%
• Misconception 2: Ignoring medium compatibility——it is necessary to confirm the chemical compatibility between the measured medium and 316 stainless steel
• Misconception 3: Excessively pursuing a wide range——the closest range level should be selected according to the actual working pressure
