一、Product Introduction
The inline sampling system is a specialized equipment designed for real-time, in-line sampling of fluids (liquid, gas, or multi-phase mixtures) in industrial production, laboratory testing, and environmental monitoring scenarios. It integrates sampling, preprocessing, and transfer functions to extract representative samples directly from pipelines or reaction systems without interrupting the normal operation of the production process.
This system eliminates the limitations of traditional off-line sampling—such as long time lags, sample contamination, and inaccurate representation—by achieving synchronous sampling with the production line. It is widely used in industries including petrochemicals, pharmaceuticals, food and beverage, environmental protection, and water treatment, providing reliable sample support for quality control, process optimization, and compliance testing.
二、Product Features
- Real-time in-line sampling: Samples are extracted directly from the pipeline without stopping production, ensuring the timeliness and authenticity of samples.
- High sample representativeness: Adopts scientific sampling point design and flow control technology to avoid sample bias caused by stratification or sedimentation of the medium.
- Integrated preprocessing function: Equipped with filtration, temperature control, pressure regulation, and degassing modules to meet the preprocessing requirements of different sample types.
- Safe and reliable operation: Built-in overpressure protection, leak detection, and explosion-proof designs (for hazardous environments) to ensure operational safety for personnel and equipment.
- Automated control: Supports PLC, DCS, or remote control, reducing manual intervention and improving sampling efficiency and consistency.
- Corrosion-resistant and durable: Key components are made of 316L stainless steel, PTFE, or special alloy materials, adapting to corrosive, high-temperature, or high-pressure media.
- Easy maintenance: Modular design simplifies disassembly, cleaning, and replacement of parts, reducing maintenance costs and downtime.
