Project Details
Hello, this is TEDDY from RS Korea's technical department. Today's post is about the replacement and calibration of the FIX 800 O2 on-site sensor installed in the AR gas storage room for welding in the semiconductor parts production process located in Anseong-si.

When requesting gas meter repair or inspection, we accept delivery by courier along with a portable meter or a brief symptom note if the quantity managed is small. However, in the case of installed measuring devices, in large quantities or included as corporate assets, it is difficult to receive delivery by courier, so it is carried out on a business trip. Calibration is also carried out through the same process as above. The inspection/calibration/repair procedure is carried out through a business trip: inquiry - quotation - visit date consultation - business trip. Travel costs vary by region. For detailed costs, please call the number below.

WANDI installation type gas meter FIX800 (left: single type / right: combination type) This is the installation type gas meter FIX800 product from WANDI, a brand specializing in gas measuring instruments. WANDI FIX800 provides a total of four sensor slots, allowing installation of two or more complex gases. Among the 40 types of gases that can be installed on Fix 800, from single to dual sensors, up to 5 gases for safety purposes in accordance with the Occupational Safety and Health Act are installed simultaneously, and the gas concentration measured in real time is displayed simultaneously.

You can check and manage measured values from outside by connecting to an electronic signboard or PLC using RS485 communication. In addition, the new product FIX AP IOT communication allows real-time monitoring through PC and mobile. Please refer to the blog post below for more details! https://blog.naver.com/rs-korea1/223638386190?trackingCode=blog_bloghome_searchlistㅣProduct Installation Purpose / Environment Inert gases such as CO2 and AR gas are often used in welding. The reason for welding with inert gas is to prevent oxidation caused by the gas generated during welding. During welding, various gases such as ozone, nitrogen oxides, and carbon monoxide may oxidize the welded metal and reduce its mechanical properties. For this reason, welding using inert gas can prevent oxidation. The company we visited this time used AR gas during welding, and it was installed to prevent worker suffocation accidents due to a decrease in oxygen concentration due to leakage of AR gas stored in the gas storage room.

●Repair and calibration

The site in question was a place with quite high humidity during the summer, so the sensor board was also corroded, so the sensor board was replaced.

It takes about 5 to 10 minutes to replace and stabilize the values. Once the value is stabilized, calibration is performed using O2 18% calibration gas. The proofreading process is repeated 2-3 times. After checking the correctly indicated calibration value, the process is completed after confirming that the atmospheric O2 concentration is normally indicated at approximately 21%. As errors occur in measured values as more than one year passes after installation and calibration, we recommend calibration on a yearly basis. This repair is completed. I'll end this post. These days, the weather is suddenly cold in a row. I hope you go around with a warm coat and I hope you finish the year 2024 well, which is just around the corner. Thank you always. See you next time! In a gas measuring environment, when you do not know the generated gas, or when you know the generated gas but cannot confirm the exact concentration, it is difficult to make a choice before purchasing. The way to ensure safety is to purchase a gas meter with an accurate measurement range by considering everything such as environmental factors, generated gas, frequency, and concentration through sufficient consultation with experts. In addition to selling simple products, RS Korea specializes in gas measurement such as self-calibration / domestic repair (A/S) / manufacturing delivery / installation work. This is a company. We provide 1:1 customized solutions for gas measurement environments based on our experience conducting demonstration / inspection / delivery / repair / installation work in various environments.

Repair items: FIX 800 O2 sensor replacement and calibration Other matters: There was no problem with the measurement, but it was installed in May 2022, so the sensor life is only about 3 months left, so we conclude the FIX 800 O2 sensor replacement and calibration blog due to the error in calibration after sensor replacement. In addition, if you have any questions about measuring various environmental factors such as gas meter, gas analyzer, measurement environment, installation/inspection inquiry, please contact us below.
