Analysis of the Application of TS303 Anti-corrosion Level Transmitter in the Chemical Industry

In the liquid level measurement of strong acid and strong alkali media in the chemical industry, the TS303 anti-corrosion level transmitter has become a key solution by virtue of its ceramic anti-corrosion technology. Through 3 typical application cases, this article analyzes the precise measurement performance of PTB603, HJ833 and other series products in corrosive media such as sulfuric acid and hydrochloric acid, providing practical reference for engineering selection.

I. Core Challenges of Liquid Level Measurement in the Chemical Industry

In the chemical production process, liquid level monitoring of corrosive media such as strong acids (such as sulfuric acid and hydrochloric acid) and strong alkalis (such as sodium hydroxide) has always been an industry pain point. When traditional metal material sensors come into contact with corrosive media, the following problems are likely to occur:

• Corrosion of the sensor diaphragm leads to inaccurate measurement
• Equipment service life is greatly shortened (the corrosion rate of ordinary stainless steel in concentrated sulfuric acid can reach 1.5mm/year)
• Risk of medium contamination affects product quality

The TS303 series anti-corrosion level transmitters developed by Xi'an Shenghongchuang Instrumentation Co., Ltd. adopt a dual-protection structure of an aluminum oxide ceramic sensor diaphragm and a polytetrafluoroethylene isolation diaphragm. They have passed GB/T 17626.6-2017 electromagnetic compatibility certification and can withstand extreme working conditions with a pH value of 0-14.

II. In-depth Analysis of Typical Application Cases

Case 1: Application of PTB603 in 98% concentrated sulfuric acid storage tank monitoring

A large chemical group originally used 304 stainless steel level gauges in titanium dioxide production by the sulfuric acid process, and they needed replacement every 3 months on average. After switching to the PTB603 anti-corrosion submersible level transmitter:

This case proves that ceramic anti-corrosion technology has a significant protective effect on concentrated sulfuric acid media, and the customer subsequently adopted HJ833 products of the same series in batches for hydrochloric acid storage tanks.

Case 2: Innovative Application of LMP836 in the Chlor-alkali Electrolysis Process

In the liquid level control of electrolytic cells containing 32% caustic soda solution, the LMP836 anti-corrosion level transmitter solves measurement difficulties through the following technological innovations:

1. Adopts a patented vented cable structure to avoid blockage caused by alkali crystallization
2. Built-in temperature compensation module, suitable for 80℃ high-temperature working conditions
3. Seamless integration with the DCS system through the HART protocol

After project implementation, the liquid level control accuracy of the electrolytic cell was improved to ±3mm, saving about 2800000 yuan in annual shutdown losses caused by abnormal liquid levels.

Case 3: Customized Solution of BXY620F in a Mixed Acid Treatment System

For the aqua regia (a 3:1 mixture of nitric acid and hydrochloric acid) storage tank of an electronic chemicals plant, our customized BXY620F solution includes:

• Thickened polytetrafluoroethylene isolation diaphragm (2.5mm)
• Special passivation treatment for the 316L stainless steel housing
• Explosion-proof upgraded version (Ex d IIC T6)

This solution has been operating stably for 18 months, saving 40% in procurement costs compared with similar imported brand products.

III. Selection Guide for Anti-corrosion Level Transmitters

Select the appropriate model according to the characteristics of the chemical medium:

Special attention should be paid during selection: the medium temperature affects the choice of sealing materials (-20℃~150℃ it is recommended to use fluororubber, above 150℃ graphite gaskets are required); the medium viscosity determines whether an additional cleaning interface is needed.
