Introduction

In level measurement of corrosive media such as strong acids and strong alkalis, the selection of the TS1003 ceramic anti-corrosion level transmitter is related to production safety and measurement accuracy. As a professional manufacturer of flow control equipment, Xi'an Shenghongchuang Instrumentation reminds you to focus on the three key parameters of anti-corrosion grade, measurement accuracy, and media compatibility, to ensure the stable performance of products in the PT124B-224, PTS602, and other series under harsh working conditions such as chemical processing and electroplating.

Anti-corrosion grade: the key to ensuring long-term stable operation

In industries such as chemical processing and electroplating, strong acid and strong alkali media are highly corrosive to level transmitters, so the anti-corrosion grade is the primary factor to consider during selection. The TS1003 ceramic anti-corrosion level transmitter uses high-purity alumina ceramic material, and its anti-corrosion performance far exceeds that of ordinary stainless steel materials, enabling it to withstand strongly corrosive media with a pH value of 1-14.

Specifically, the anti-corrosion grade should refer to the following standards:

• Material certification:Complies with the ISO 28706-1 standard, ensuring the stability of ceramic materials in media such as sulfuric acid and hydrochloric acid
• Sealing performance:IP68 protection rating, preventing medium penetration from causing corrosion of internal circuits
• Actual operating condition verification:Models such as PT124B-224 and DS2640 have operated continuously in concentrated sulfuric acid storage tanks for more than 3 years

It is recommended to select the corresponding model according to the corrosiveness of the medium:

Measurement accuracy: directly affects process control performance

Accuracy errors in level measurement may trigger chain reactions, ranging from affecting product quality to causing safety accidents. The TS1003 series uses German-imported ceramic capacitive cores combined with a temperature compensation algorithm to achieve industry-leading accuracy of ±0.2%FS within a 0-10m measuring range.

Three major technical guarantees for improving accuracy:

1. Multilayer ceramic composite technology:Eliminates measurement deviations caused by changes in medium density
2. Digital signal processing:Built-in 32-bit MCU corrects nonlinear errors in real time
3. On-site calibration function:Models such as PY202 support remote calibration via the HART protocol

Actual application data shows:

• In electrolyzer applications in the chlor-alkali industry, LMK807 maintained continuous measurement fluctuation of <3mm for 6 months
• PTH602 in a 98℃ phosphoric acid storage tank has a daily drift of <0.05%

Media compatibility: the core indicator for avoiding selection errors

Different corrosive media react very differently with sensor materials. Through testing in more than 200 operating conditions, Xi'an Shenghongchuang Instrumentation found that hydrofluoric acid requires specially treated Hastelloy diaphragms, while concentrated nitric acid is suitable for standard ceramic materials.

Key points for media selection

1.Chemical composition analysis:The halide ion content in the medium must be clarified (for example, fluoride and chloride ions accelerate corrosion)
2. Physical state consideration:For media containing solid particles, the CYB-32 model with a flushing port should be selected
3. Temperature-pressure coupling:For high-temperature and high-pressure operating conditions, it is recommended to use the reinforced structure of the TS1003

Typical application matching

• Electroplating wastewater treatment:The platinum electrode version of DS2640 can detect lead-containing wastewater
• Lithium battery electrolyte:PCM264 is equipped with a special Teflon coating to handle organic solvents

Summary and professional recommendations

When selecting a ceramic anti-corrosion level transmitter, it is recommended that enterprise decision-makers:
1. Require suppliers to provide material test reports and operating condition case studies
2. Give priority to products with ISO9001 and SIL2 certifications
3. Conduct on-site sample testing and verification for key models such as PT124B-224
