How to select the CYH-330F anti-corrosion level transmitter? The best choice for strong acid and strong alkali environments
Added to Favorites:125

In corrosive environments such as strong acids and strong alkalis, how can you choose a reliable CYH-330F anti-corrosion level transmitter? As a professional flow control equipment manufacturer, we analyze for you the performance advantages of PTFE sensors in media such as sulfuric acid and hydrochloric acid, and provide a selection guide for split-type level transmitters such as PCM262 and STLP.


I. Core Definition and Industry Background of Anti-corrosion Level Transmitters


Corrosive media such as sulfuric acid, hydrochloric acid, and sodium hydroxide have long troubled industries such as chemical processing, electroplating, and pharmaceuticals due to the corrosion of traditional metal sensors. The CYH-330F anti-corrosion level transmitter uses a PTFE housing and isolation diaphragm, whose stable molecular structure can resist 98% concentrated sulfuric acid, 37% hydrochloric acid, and strong acid and alkali environments with a pH value of 1-14. According to the 2023 report of the China Instrument and Control Society, annual losses caused by sensor corrosion in the chemical industry exceed 1.2 billion yuan, while level transmitters protected by PTFE can extend equipment service life by 3-5 times.


II. Technical Performance Comparison: Differences Between PTFE and Conventional Materials


We selected 5 common materials on the market for comparative testing:


Material TypeSulfuric acid resistant (98%)Hydrochloric acid resistant (37%)Maximum TemperatureReference Price Range
316L Stainless Steel≤30 days corrosion≤15 days corrosion200℃Mid-to-low range
Hastelloy≤180 days≤90 days400℃High-end
PolytetrafluoroethyleneNo corrosionNo corrosion260℃Upper mid-range

Test data show that when models such as PT601S and DCT202 use PTFE material, they can still maintain 5000 hours without permeation in a 40% hydrofluoric acid environment, and their performance far exceeds the ceramic material used in UDTB split-type transmitters.


III. Selection Guide for Split-type Level Transmitters


For different operating condition requirements, we recommend selecting according to the following priorities:

  • Highly corrosive environments: CYH-330F or PCM262 split submersible level transmitters are the preferred choice, and their remote signal transmission function can prevent on-site instruments from contacting the medium
  • High-temperature and high-pressure conditions: The HPT-35 split-type transmitter adopts a special sintering process, with pressure resistance up to 25MPa
  • Custom calibration required: The STLP split-type transmitter supports user-defined ranges and output signals (4-20mA/RS485)
  • Projects with limited budgets: The BYP266 split-type transmitter offers the best cost performance within the pH2-12 range

IV. Typical Application Scenarios and Installation Points


In electroplating tank level monitoring, the installation of the PT3023 split submersible level transmitter requires attention to the following:

  1. The sensor head must be completely immersed in the liquid to avoid bubbles adhering and affecting accuracy
  2. The remote transmission cable should avoid sources of strong electromagnetic interference, and it is recommended to use shielded twisted-pair cable
  3. Refer to the YM-35 split submersible level transmitter manual; the probe needs to be rinsed with clean water every month
