In the field of liquid level measurement for highly corrosive media, the WMY-SFYX anti-corrosion level transmitter stands out by virtue of its PTFE material and military-grade sealing process. As a core product of Xi'an Shenghongchuang Instrumentation Co., Ltd., it solves measurement challenges under highly corrosive conditions such as sulfuric acid and hydrochloric acid through 5 major technical advantages, providing technical evaluators with a one-stop solution featuring high precision and long service life.

I. Industry Background and Market Pain Point Analysis

Industries such as chemicals, electroplating, and pharmaceuticals have long faced the challenge of liquid level monitoring in strong acid and strong alkali media. When traditional metal sensors come into contact with 98% concentrated sulfuric acid or 40% hydrofluoric acid, their average service life is less than 3 months. According to GB/T 17626-2018 standard testing, the WMY-SFYX anti-corrosion level transmitter adopts an integrally encapsulated PTFE structure, improving corrosion resistance to more than 20 times that of ordinary 316L stainless steel, completely solving measurement failure caused by material corrosion.

II. Technical Analysis of 5 Core Advantages

1. Military-Grade Sealing Process

It adopts IP68 protection-grade sealing technology and has passed a 2000-hour salt spray test (ASTM B117 standard), ensuring no penetration in extreme environments with a pH value of 0-14. Compared with similar products such as DB-88, its sealing service life is extended to 5 years (industry average: 2 years).

2. Dynamic Temperature Compensation Technology

A built-in PT100 temperature sensor, combined with an adaptive algorithm, still maintains 0.2%FS accuracy under operating conditions from -20℃~120℃. Actual test data show that in an 80℃ concentrated hydrochloric acid environment, the temperature drift error of model PT-3022 is only 0.05%/10℃, outperforming the industry benchmark value of 0.1%.

3. Modular Rapid Maintenance Design

The original plug-in sensor module (Patent No. ZL202320XXXXXX) shortens replacement time from the traditional 2 hours to 15 minutes. The BYP-264 model has achieved 4 years of continuous operation for a single device without fault records in a Sinopec ethylene project.

4. Intelligent Signal Processing System

Equipped with a 32-bit ARM Cortex-M4 processor, it can automatically identify and filter false signals caused by air bubbles and foam. In 98% sulfuric acid level measurement, the fluctuation amplitude of model PH-356 is controlled within ±1mm (industry norm: ±5mm).

5. Full-Range Linear Calibration

Using laser calibration technology, the measuring range covers 0-20 meters, with nonlinearity error ≤0.1%. Tested by SGS, model LMK-858 controls the error at each point within 0.08% during segmented calibration from 0-10 meters.
