DLK208 Corrosion-Resistant Level Transmitter vs Ordinary Sensor: Service Life Comparison Test
Added to Favorites:125

In corrosive media environments such as strong acids and strong alkalis, ordinary level sensors often have a short service life. Through comparative tests between the DLK208 anti-corrosion level transmitter and ordinary sensors, Xi'an Shenghongchuang Instrumentation Co., Ltd. verified the outstanding durability of products such as the PTG602 and LMK858 series featuring ceramic anti-corrosion technology under harsh working conditions.

I. Industry Background and Market Pain Point Analysis

Industries such as chemicals, electroplating, and pharmaceuticals have long faced equipment wear problems caused by highly corrosive media. According to statistics from the China Industrial Anti-corrosion Technology Yearbook, unplanned downtime losses caused by sensor corrosion alone exceeded 1.2 billion yuan in 2022. Under working conditions with pH values <2 or >12, traditional stainless steel sensors have an average service life of less than 6 months. Frequent replacement not only increases procurement costs, but may also lead to production interruptions and safety accidents.

Market research shows that 83% of respondents are most concerned about three core indicators: ① measurement accuracy stability in extreme environments ② total cost of ownership over the product life cycle ③ whether it complies with ISO 12944 anti-corrosion rating standards. This is precisely the technological breakthrough point of professional products such as the DLK208 anti-corrosion submersible level transmitter and ceramic anti-corrosion sensors for measuring strong acid and strong alkali liquid levels.

II. Comparative Test of Key Performance

In an 18-month accelerated corrosion test, we simulated hydrochloric acid (5%-37%) and sodium hydroxide (10%-50%) environments at different concentrations, and the comparative test results are as follows:

Test ItemOrdinary 316L SensorDLK208 Ceramic Corrosion-Resistant Type
Degree of Appearance CorrosionObvious pitting corrosion appears after 6 monthsNo visible changes after 18 months
Zero Drift±3.5%FS/year±0.2%FS/year
Average Failure Cycle4-8 monthsMore than 36 months

III. Analysis of Core Technologies

The DLK208 series adopts a triple protection system: ① 99% alumina ceramic measuring diaphragm ② PTFE sealing isolation layer ③ special alloy pressure-guiding cavity structure. This combination enables the product to maintain 0.1% measurement accuracy while resisting all highly corrosive media except hydrofluoric acid. Tested by SGS, its performance fully complies with the following standards:

  • GB/T 17626.6-2017 electromagnetic compatibility requirements
  • HJ/T 103-2003 technical requirements for environmental protection products
  • ISO 1817:2015 liquid resistance performance of rubber

IV. Typical Application Scenarios

In a case at a large chlor-alkali chemical plant in Shaanxi, the originally used CYB-31MS anti-corrosion submersible level transmitter required complete replacement every 9 months. After switching to the DLK208 series:

  1. Continuous equipment operation time increased from 278 days to 1265 days
  2. Annual maintenance costs decreased by 67%
  3. The number of unplanned shutdowns caused by instrument failures dropped to zero

V. Procurement Decision Guide

For different medium characteristics, we recommend:

Media TypeRecommended ModelsExpected service life
Concentrated sulfuric acid(98%)PTG602/PTP602 SeriesMore than 5 years
Mixed Organic AcidsLMK858/SY2088F Series3-4 years
High-Temperature Alkaline LiquidCL194/LC-503 Series4-5 years
