The Core Value of Diffused Silicon Hogsman Pressure Transmitters in Industrial Automation

As a classic model of diffused silicon Hogsman sensors, the MBS1900 pressure transmitter demonstrates outstanding performance in the field of industrial automation. This article will explain in detail 4 major application solutions for series products such as P-P964 and P-P972, helping operators resolve selection concerns and understand the core advantages and application techniques of diffused silicon Hogsman sensors in flow control. With its features such as high stability and strong anti-interference capability, diffused silicon technology has become the preferred solution for pressure monitoring in industries such as petrochemicals and electric power metallurgy.

1. Petrochemical Industry: Precise Monitoring in High-Temperature and High-Pressure Environments

In refining units, the P-P964 pressure transmitter uses a 316 stainless steel isolation diaphragm and Hastelloy C wetted materials, and can withstand the effects of 6.89MPa static pressure. Its direct digital capacitance circuit can accurately capture pressure fluctuations of 0.16~10MPa in the reactor, and the temperature compensation technology ensures ±0.1% accuracy under operating conditions of -40~100℃. In practical applications, attention should be paid to installation coordination with the domestic capacitive pressure transmitter FB3351DR high-precision intelligent differential pressure transmitter. The former focuses on process pressure monitoring, while the latter specializes in differential pressure flow measurement.

A typical case shows that after a certain ethylene cracking unit adopted the P-P972 series, the pressure control error was reduced from ±1.5% to ±0.25%, and unplanned shutdowns were reduced by 3 times annually. Key operating points include: regularly calibrating static pressure error, selecting fluororubber seals to handle acidic media, and maintaining the damping time constant at 4-6s to filter pump valve vibration interference.

2. Power Industry: Boiler System Safety Monitoring Solution

The DG1300-BZ-A-0.4/CJ/AE/FZ/W model is specially designed for power station boilers, and its features include:

• Range 5 covers 40.0~200kPa, matching steam drum pressure monitoring requirements
• Exd Ⅱ CT6 explosion-proof certification, compliant with IEC801 electromagnetic radiation standards
• Square root output mode optimizes steam flow calculation

Compared with conventional products, this model still maintains ±0.25% span accuracy after a 140kgf/cm² overpressure test. During operation and maintenance, note the following: check the silicone oil filling status monthly to avoid diaphragm overload; when used together with the FB3351DR differential pressure transmitter, it is recommended to uniformly use the HART protocol for remote parameter calibration.

3. Metallurgical Industry: Reliable Solutions for Extreme Working Conditions

The 064G-G6532 model performs outstandingly in continuous casting units, and its technical advantages are reflected in:

In practical applications, it has been found that when used with a Monel diaphragm, it can effectively resist corrosion from sintering flue gas. It is recommended to perform zero-point drift detection quarterly, and when the error exceeds 0.5%, it should be returned to the factory for calibration immediately.

4. Water Treatment Industry: Multi-Parameter Coordinated Control System

The application solution of the BP-A series in sewage treatment plants includes three levels:

1. Influent Monitoring: Using the P-P974 model, range 3 covers 0.2~6.0kPa, monitoring the differential pressure before and after the bar screen
2. Aeration Control: MBS1900 used together with FB3351DR achieves dual-parameter adjustment of DO and air pressure
3. Sludge Conveying: The M5156-000005-016BG model is equipped with a polyurethane resin coating, improving wear resistance by 60%

Key operation tips: regularly clean the pressure interface to prevent biofilm adhesion; during the rainy season, adjust damping to 8-10s to cope with sudden flow changes.

Professional Selection Recommendations and Maintenance Points

Based on 20 years of industry service experience, it is recommended that users focus on:

• Medium Characteristics: For corrosive fluids, Hastelloy diaphragms should be preferred
• Range Selection: Normal working pressure should be within 30%~80% of the range
• Certification Requirements: Exia/Exd certified products must be selected for explosion-proof locations

The full range of diffused silicon Hogsman sensor products provided by Xi'an Shenghongchuang Instrumentation Co., Ltd. have all passed ISO9001 quality system certification. For scenarios requiring higher accuracy, you may consider upgrading to the FB3351DR series differential pressure transmitters, whose ±0.075% accuracy performance can meet the needs of most precision control applications.
