Introduction

When purchasing an EA118 split-type submersible level transmitter, which matters more, the manufacturer's quality or the price? As a professional manufacturer of flow control equipment, Xi'an Shenghongchuang Instrumentation Co., Ltd. analyzes the working principles and selection points of models such as UMD-98 and BXY620C3 for you, helping information researchers weigh cost performance and find the most suitable solution.

Core Value of Split-type Submersible Level Transmitters

As key equipment in the field of industrial automation, split-type submersible level transmitters are widely used in industries such as chemical, petroleum, and water treatment. Their core function is to accurately measure liquid level height and convert the signal into a standard electrical signal output, enabling remote monitoring and control. Among the many models, such as UMD-98 and BXY620C3, although their working principles are similar, there are significant differences in performance parameters, applicable environments, and service life.

Working Principle and Technical Requirements

Taking the BXY620C3 split-type submersible level transmitter as an example, it uses a diffused silicon piezoresistive sensor to estimate the liquid level height by measuring the hydrostatic pressure of the liquid. This design places extremely high requirements on the sensor's sealing performance, corrosion resistance, and temperature compensation capability. If the manufacturer uses inferior materials to reduce costs, it may lead to increased measurement errors or shortened equipment life.

Trade-off Between Quality and Price

When purchasing split-type submersible level transmitters, information researchers often face the dilemma of choosing between quality and price. Low-priced products may save costs in the short term, but in the long run, frequent maintenance and replacement, as well as potential production risks, will bring greater losses.

Key Quality Indicators

1.Accuracy Class: For example, the typical accuracy of the EA118 split-type submersible level transmitter is ±0.5%FS, while low-end products may only reach ±1.5%FS.
2. Environmental Adaptability: The IP68 protection rating of the HM21R model can handle extreme working conditions, while simplified versions may only support IP65.
3. Long-term Stability: The annual drift rate of high-quality models such as EB2088T can be controlled within 0.1%.

Price Composition Analysis

The price differences of split-type submersible level transmitters mainly come from:
- Core sensor type （diffused silicon vs piezoresistive ceramic）
- Housing material （316L stainless steel vs ordinary 304）
- Certification standards （CE/Ex certification vs no certification）
Taking the DS2620 manufacturer as an example, it reduces unit costs through large-scale production while maintaining the ISO9001 quality management system.

Mainstream Model Comparison and Selection Recommendations

Precautions for Purchase

1.Clarify Requirements: For example, the MK-136 split-type submersible level transmitter is suitable for ordinary water treatment, while corrosive media require special models such as AOB-136.
2. Verify Qualifications: Authorized suppliers should provide documents such as SIL certification and explosion-proof certification.
3. After-sales Service: High-quality manufacturers usually provide a warranty of 18 months or more.

Industry Trends and Technological Innovation

With the development of Industry 4.0, split-type submersible level transmitters are showing an intelligent trend:
- Digital signal output is replacing traditional 4-20mA analog signals
- Addition of self-diagnostic functions （such as the fault warning system of EB2088T）
- Application of wireless transmission technology （LoRaWAN/NB-IoT）
These advances have reduced equipment maintenance costs by more than 30%, but at the same time have placed higher demands on the manufacturer's R&D capabilities.
