In harsh industrial environments such as strong acids and alkalis, how to achieve precise liquid level measurement has become a core pain point for technical evaluators. The CYH-136ZF anti-corrosion level transmitter uses military-grade polytetrafluoroethylene material and is specially designed for highly corrosive media such as sulfuric acid and hydrochloric acid. Through IP68 protection rating and special sealing technology, it thoroughly solves the problems of traditional sensors being prone to corrosion and having short service life.

I. Industry Background and Market Analysis

With the growing demand for strong corrosive media measurement in industries such as chemicals, pharmaceuticals, and electroplating, the limitations of traditional level sensors have become increasingly prominent. According to statistics, the global market for corrosive media measurement equipment is growing at an annual rate of 8.7%, with the Asia-Pacific region accounting for more than 40%. Based on 15 years of sensor R&D experience, Xi’an Shenghongchuang Instrumentation Co., Ltd. has developed the CYH-136ZF series for this market segment, which has been successfully applied in 32 large chemical enterprises across China.

II. Technical Performance and Core Advantages

This product adopts a three-layer composite protection structure: 1) the media-contact layer is 5mm-thick polytetrafluoroethylene (PTFE), with acid and alkali resistance reaching the ASTM D543 standard; 2) the intermediate layer uses 316L stainless steel bellows for isolation; 3) the outer layer is an IP68 protective housing. Key parameters include: measurement accuracy ±0.25%FS, operating temperature -20~120℃, and maximum pressure resistance of 16MPa, far exceeding similar competing models such as WMY-SFYX and DB-88.

III. Typical Application Scenarios

1) Electroplating production line: after a listed company adopted the BYP-264 model, it solved the problem of inaccurate chromic acid solution measurement, and annual maintenance costs were reduced by 67%; 2) Pesticide production: the PH-356 operated continuously for 18 months without failure in a 40% sodium hydroxide environment; 3) Wastewater treatment: compared with the PT500-602, the LMK-858 achieved a 300% increase in service life in media containing hydrofluoric acid.

IV. Procurement and Selection Guide

Technical evaluators need to focus on: 1) compatibility between medium concentration and temperature (refer to the operating condition curve of UBY-3131); 2) process connection method (thread/flange); 3) whether explosion-proof certification is required (Ex d IIC T6). Xi’an Shenghongchuang provides more than 20 derivative models such as ND-23, supports non-standard customization, and shortens delivery time by 30% compared with the industry average.
