SK-7500-LEL-BY LEL on-line monitoring system is an on-line monitoring system for continuous monitoring of organic matter LEL (lower explosive limit) content in pipelines. The system integrates gas sampling, pretreatment, concentration detection, data display and communication, and realizes on-site unattended. It has the characteristics of simple structure, wide dynamic range, strong real-time performance, flexible networking, low operating cost, and can communicate with enterprise DCS systems.
1. Pre-processing, High Accuracy, Small Overall Size, Easy Installation. 2. Professional gas pretreatment for humid, tar, dust and other harsh environments in complex production environments. 3. Using the original high-performance Sensor, long life, good anti-interference performance, can simultaneously monitor a variety of gases, accurate and stable data. 4. Equipped with an infrared remote control, full-function operation can be achieved without opening the lid. Standard 4-20mA, RS485 and a set of relay output signals, easy to access industrial control systems such as PLC, DCS or stand-alone control. 6. Optional wireless modules such as DTU and LORA can be used to upload data to the enterprise DCS system or third-party platform in real time. 7. Optional 7-inch industrial touch display, real-time concentration and Linear dispersion map display is more intuitive and clear.
The system adopts active sampling method. First, the sample gas in the pipeline is extracted and processed into a clean, drying and constant gas through the gas sampling subsystem (including pre-treatment units such as sampling pump, filtrate, and condensation). The processed sample gas is sent to the detection instrument (SK/MIC-600-LEL-Y). The detection instrument works based on the principle of infrared NDIR, and uses the absorption characteristics of different gas molecules to specific wavelengths of infrared light to identify gas components and determine their LEL concentration according to Lambert-Beer's law, and finally displays and outputs the measurement results.
Generally used for RTO front-end pipeline monitoring to prevent places with high concentration and explosion hazard

1. Determine the installation point according to the sampling station point selection requirements (such as priority selection of vertical pipe sections and negative pressure areas, avoiding specific locations). 2. Install the equipment according to the installation method (such as φ 45 welded flange or threaded adapter). 3. Connect the system power supply (AC220V) and the corresponding signal output cable (such as three-core Shielding cable for 4-20mA, four-core Shielding cable for RS485). 4. If the optional Back flushing or heat tracing system, connect the corresponding gas source (clean instrument air) or heat tracing pipeline. 5. The system is powered on, and parameter setting, zero adjustment or target point calibration are carried out through the infrared remote control or built-in buttons. 6. The system starts automatic sampling, preprocessing, detection and display of concentration data, which can be connected to the host computer system through the output signal.
* The sampling station should prioritize the vertical pipe section and the negative pressure area of the flue to ensure sample representativeness. Measurement location should avoid flue elbows and parts with sharp changes in section. Please refer to the product information for specific distance requirements. The system power supply is AC220V, and the cable selection must meet the specifications. For long-distance transmission, the wire diameter should be thickened and the grounding should be done well. * If the Back flushing function is selected, it is necessary to provide clean, oil-free and water-free instrument air, and the pressure and flow should be stable within the required range. * Equipment Ambient Temperature should be between 0~ 50 ℃, humidity ≤ 95% RH (no condensation). Applicable pipeline working conditions are temperature ≤ 200 ° C, no or trace dust and water vapor, and slightly negative pressure, normal pressure or positive pressure. Equipment requires vibration (≤ 100 Hz), which needs to be considered during installation. During operation and maintenance, the infrared remote control can be used to operate without opening the lid to avoid misoperation. * Note that the explosion-proof grade is ExdIIBT4/6Gb, and it needs to be used in a place that meets the explosion-proof requirements. * If there is a conflict between the system execution standards and the latest standards, the latest standards shall prevail.
