Want to monitor multiple gas components accurately and reliably? ABB EL3020 gas analyzer is your ideal choice, it combines advanced NDIR technology with a gas-filled climate radiation detector to ensure excellent performance. As a professional supplier, Tongtu not only provides this high-performance analyzer, but also has a wide range of models for you to choose from. Whether you are using it for process control or environmental monitoring, we can find a model that suits you.
ABB EL3020 has a modular design, which is easy to maintain and upgrade. Its sample gas chamber is easy to clean, and the gas path is made of corrosion-resistant materials to extend the service life of the equipment. In terms of power supply, it is compatible with a wide range of AC power supplies (100-240VAC±10%, 48-63Hz), with a single-channel power consumption of about 40VA and a dual-channel power consumption of about 70VA. It has a rich output interface, providing 0/2/4-20mA analog signals (maximum load 750Ω), and supports Modbus, RS485 and RS232 digital communication protocols. It also has EEx(p) explosion-proof certification and provides an optional heating design to adapt to extreme temperature environments. The built-in pressure sensor (working range pabs=600-1250hPa) can automatically correct the impact of pressure fluctuations on measurement accuracy.
Zero calibration: ABB EL3020 uses high-purity nitrogen. The equipment needs to be preheated for more than 12 hours. Stop purging and sampling, connect nitrogen, switch to the zero position through the five-way valve, adjust the pressure to 0.01MPa, keep the flow rate at 60L/h, purge the gas chamber with nitrogen for 12 minutes, and enter a small standard value (such as +2ppm) through the panel operation for calibration and save.
Range calibration: Taking CO as an example, it also needs to be preheated for more than 12 hours. Stop purging and sampling, connect CO standard gas, switch the five-way valve to the calibration position, adjust the pressure and flow as above, purge the gas chamber for 12 minutes, select CO through the panel operation, enter the accurate nominal value on the standard gas bottle, and confirm and save the calibration value after the reading stabilizes.
How fast does this analyzer respond?
The response time of ABB EL3020 is very fast, usually less than 3 seconds, and can quickly reflect changes in gas concentration.
What should be paid special attention to during installation and maintenance?
During installation, it is important to ensure the airtightness of the gas pipeline, which is the basis for accurate measurement. In terms of maintenance, regular calibration is essential. The sample chamber can be cleaned, which is also part of the routine maintenance content
