If you are looking for wholesale channels for high-performance pressure transmitters such as MB-MB320 and DG-DG1300, we provide stable and reliable industrial sensor solutions to meet various flow control needs, and welcome your inquiries and orders.

Technical advantages and industry applications of diffused silicon Hesseman sensors

Diffused silicon Hesseman pressure sensors have become the preferred choice in industries such as electric power, metallurgy, and petrochemicals due to their excellent stability and accuracy. Their core principle is based on the piezoresistive effect of silicon crystals, forming a Wheatstone bridge through precision etching technology to achieve linear conversion of pressure signals. Compared with traditional strain gauge sensors, diffused silicon technology has significant advantages such as small temperature drift (±0.25%/55℃) and high long-term stability (six-month error ±0.15%). Xi'an Shenghongchuang Instrument Co., Ltd. uses original German Hesseman chips combined with its self-developed temperature compensation algorithm, enabling models such as SSK-SSK207 to maintain a measurement accuracy of ±0.1%FS within the operating range of -40～100℃.

Comparative analysis of key performance parameters

Procurement selection guide and common misconceptions

When selecting pressure transmitters such as PT-PT211, operators need to focus on the following factors:

• Media compatibility: For corrosive media, diaphragms made of Hastelloy C or Monel should be selected
• Turndown ratio: It is recommended that the actual working pressure be within the 30%-80% range of the measuring span. For example, the 40:1 turndown ratio of the KYB-G series can greatly reduce replacement frequency
• Output signal: The digital signal of 4-20mA+HART protocol is more suitable for remote monitoring scenarios
• Common misconception: It is mistakenly believed that high accuracy must be accompanied by high cost. In fact, models such as CYB-42 have achieved both ±0.1% accuracy and affordable pricing through scaled production

Industry solutions and successful cases

In a large petrochemical project in Shaanxi, we equipped the MT-MT208 pressure transmitter with fluororubber seals and a silicone oil filling system, successfully solving measurement difficulties in high-temperature hydrogen sulfide environments. This solution was achieved through the following technological innovations:

1. A multilayer composite diaphragm structure was adopted, increasing the pressure resistance rating to 13.76MPa
2. A built-in self-diagnosis function monitors the health status of the sensor in real time
3. Passed the IEC801 standard electromagnetic compatibility test, improving anti-interference capability by 60%
