In the field of liquid level measurement for corrosive media such as strong acids and strong alkalis, the CYT-152 anti-corrosion level transmitter stands out with its PTFE material and special structural design. This article provides a professional comparison of the anti-corrosion performance, measurement accuracy, and customization requirements of different models such as PTB603 and HJ833, helping engineering implementers quickly match the optimal solution for harsh working conditions in chemical processing, electroplating, and other industries.

In industries such as chemical processing, electroplating, and pharmaceuticals, liquid level measurement of corrosive media such as strong acids and strong alkalis has always been a technical challenge. Traditional level transmitters are often unable to withstand corrosion in these extreme environments, resulting in inaccurate measurement or even equipment damage. To address this pain point, Xi'an Shenghongchuang Instrument Co., Ltd. has developed a series of anti-corrosion level transmitters, including models such as CYT-152, PTB603, and HJ833, using PTFE or ceramic anti-corrosion materials to provide reliable solutions for harsh working conditions.

1. Core Advantages of Anti-corrosion Level Transmitters

The core advantages of anti-corrosion level transmitters lie in their special materials and structural design. PTFE has excellent chemical stability and can resist the erosion of the vast majority of corrosive media such as strong acids, strong alkalis, and organic solvents. Ceramic materials, on the other hand, offer higher hardness and wear resistance, making them suitable for media containing solid particles.

• Corrosion Resistance:CYT-152 adopts an all-PTFE material and can withstand strong corrosive media such as 98% sulfuric acid and 37% hydrochloric acid.
• Measurement Accuracy:The PTB603 ceramic anti-corrosion model achieves an accuracy of ±0.2%FS, meeting high-precision measurement requirements.
• Structural Design:HJ833 adopts a special sealing structure to prevent media from penetrating into the internal circuitry.
• Customization Service:PRC-918 supports customized parameters such as measurement range and output signal.

3. How to Choose the Right Model

When selecting an anti-corrosion level transmitter, the following key factors need to be considered:

1. Media Characteristics:First, clarify parameters such as the corrosiveness, temperature, and density of the medium. For strong acid and strong alkali media, CYT-152 or T-51B is an ideal choice; for media containing solid particles, PTB603 or LMP836 is more suitable.
2. Measurement Range:Select the appropriate range according to the actual liquid level height. The EVT-300B series offers various options from 0-5m to 0-50m.
3. Accuracy Requirements:For high-precision measurement, TS303 or BXY620F can be selected, with accuracy up to ±0.1%FS.
4. Installation Method:Different installation methods such as submersible, flange-mounted, and threaded are suitable for different working conditions.

4. Customized Solutions

For special working conditions, Xi'an Shenghongchuang Instrument Co., Ltd. provides comprehensive customized services:

• Special Materials:PRC-918 can use special anti-corrosion materials such as Hastelloy and titanium according to requirements.
• Signal Output:Supports multiple output methods such as 4-20mA, HART, and RS485.
• Certification Requirements:Products with international certifications such as ATEX and SIL can be provided.
• Special Structure:For high-temperature and high-pressure working conditions, heat dissipation structures or reinforced sealing can be customized.

5. Application Case Sharing

In a sulfuric acid storage tank level monitoring project at a large chemical plant, the previously used ordinary level transmitter had an average service life of only 3 months. After being replaced with the CYT-152 anti-corrosion level transmitter, it has operated stably for 18 months, greatly reducing maintenance costs. Measurement data is uploaded to the DCS system via the HART protocol, enabling precise level control and alarm functions.

Another case is the chromic acid tank level measurement in an electroplating plant, where a customized AC-L3 anti-corrosion level transmitter was adopted. The specially designed probe structure avoided measurement errors caused by crystallization of the electroplating solution, and the accuracy has remained within ±0.3%FS over the long term.
