In high-temperature industrial environments, the UMD-98 high-temperature guided-pressure level transmitter adopts an innovative stainless steel cable-cylinder design, effectively solving the challenge of water level measurement under ultra-high-temperature conditions above 500℃. This article will analyze from three dimensions—core parameters, structural advantages, and typical applications—how this professional-grade level monitoring device ensures stability and accuracy under extreme temperatures.

I. Core Technical Parameters and Performance Advantages

The core advantage of the UMD-98 high-temperature guided-pressure level transmitter lies in its high-temperature resistance. Featuring a 316L stainless steel cable-cylinder structural design, it can operate stably for long periods in extreme environments from -40℃ to 500℃, and withstand temperatures up to 550℃ for short durations. Compared with ordinary level sensors that experience signal drift above 300℃, this product combines patented guided-pressure technology （Patent No.: CN2018XXXXXX） with a ceramic capacitive sensing element to achieve high-accuracy measurement of ±0.5%FS.

Key performance indicators include: selectable measuring ranges from 0-0.5m to 0-20m; output signal 4-20mA+HART protocol; process connection flange DN50 to DN150; protection rating IP68. These parameters place it in a leading position among similar products. When used together with Domestic Weighing Sensor DYLY-103/106/108 Tension and Compression S-type Stainless Steel Weighing Sensor, it can form a complete industrial weighing and measurement system.

II. Structural Design and Industry Application Analysis

The breakthrough design of this product lies in its triple-protection structure: 1）multi-layer metal bellows isolation technology, effectively blocking direct conduction from high-temperature media; 2）vacuum-sealed cavity design, avoiding measurement errors caused by thermal expansion; 3）special sintered filter membrane, preventing particles from clogging the pressure-guiding hole. This structure is particularly suitable for the following scenarios:

• Petrochemical catalytic cracking units （reaction temperature 480-520℃）
• Boiler drum water level monitoring in thermal power plants （pressure 4-16MPa）
• Molten metal storage tanks in the metallurgical industry （medium temperature 600-1200℃）
• Molten salt storage tanks in solar thermal power generation （operating temperature 565℃）

III. Comparative Analysis and Selection Recommendations

Compared with traditional differential pressure level gauges, the UMD-98 has obvious advantages under high-temperature operating conditions:

During selection, key attention should be paid to medium characteristics, installation space, and compatibility with supporting instruments. For scenarios that also require force measurement, it can be used together with DYLY Series Weighing Sensor, whose features of 5kg-20t measuring range and 0.02% accuracy can complement the UMD-98.

IV. Standard Certifications and Quality Assurance

The product strictly complies with international standards: certified under the ISO9001:2015 quality management system; explosion-proof certification complies with ATEX/IECEx standards （Ex d IIC T6 Gb）; process connections comply with the ASME B16.5 flange standard. As a national high-tech enterprise, Xi'an Shenghongchuang Instrument Co., Ltd. has a CNAS-certified laboratory, and every unit shipped from the factory undergoes a 72-hour high-temperature aging test and third-party metrological verification.
