Introduction

In high-temperature industrial environments, accurate liquid level measurement is crucial to production safety. Xi'an Shenghongchuang Instrument's TS304 high-temperature pressure-guided level transmitter adopts a stainless steel cable-barrel structure, innovatively solving the challenge of liquid level monitoring under ultra-high-temperature conditions above 400℃. This article provides an in-depth analysis of the innovative technologies of product series such as UMD-98 and CYB-34, offering technical evaluators a comparison of key performance parameters.

Technical Breakthroughs in High-Temperature Pressure-Guided Level Transmitters

Traditional liquid level measurement equipment faces challenges such as material deformation and signal drift in high-temperature environments above 400℃. The TS304 series uses a 316L stainless steel cable-barrel structure and achieves physical isolation between the medium and the sensing element through pressure-guiding isolation technology, while being equipped with a ceramic capacitive sensor core to ensure accuracy of ±0.5%FS within the range of -40℃~450℃. Its innovation is reflected in three aspects:

• Multi-layer thermal barrier design: A gradient heat dissipation structure is adopted in the UMD-98 model, allowing the heat of the high-temperature medium to attenuate step by step
• Dynamic temperature compensation: CYB-34 has dual built-in PT100 temperature sensors to correct temperature drift errors in real time
• Cable anti-aging treatment: The ETFE cable outer layer of the ND-24 series is added with a silicone-based protective coating, extending service life by 3 times

Comparison of Key Performance Parameters

Engineering Advantages of the Stainless Steel Cable-Barrel Structure

The modular cable-barrel design used in models such as CS-PT450 has significant advantages over traditional flange installation methods. Its 316L stainless steel housing has passed the ASTM G48 standard test, with pitting corrosion resistance in chloride-containing media exceeding PREN40. Technical evaluation should pay special attention to:

1. Installation convenience: The XT21R series supports vertical/horizontal installation in any orientation, with no need to stop the tank or empty it
2. Maintenance cost: The detachable sensing module of BTL902 reduces replacement time from 8 hours to 30 minutes
3. Signal stability: The double-shielded cable can still maintain 0.1% signal purity in inverter environments

Measurement Reliability Assurance in High-Temperature Environments

For the temperature shock conditions commonly seen in the metallurgical industry, the TT21 model has developed a thermal shock adaptive algorithm. When a temperature change rate of >5℃/s is detected, it automatically enables the backup sensor parallel operating mode, avoiding measurement errors caused by steam condensation. This technology has obtained CNAS certification and has achieved continuous zero-failure operation for 18 months in the application of a 2350m³ blast furnace of a certain steel group.

Technical Extension of Related Measurement Equipment

In the field of industrial weighing, Domestic Weighing Sensor HGQS2 Truck Scale Bridge-Type Weighing Sensor Force Sensor Silo Hopper Scale also demonstrates outstanding performance. Its alloy steel material and 0.02 accuracy grade can meet range requirements from 5kg to 20t, making it especially suitable for forming a combined monitoring system together with level transmitters. Through a creep compensation algorithm, this product still maintains a comprehensive accuracy of ±0.03% in a high-temperature environment of 65℃.
