From installation to use: full process guide for fixed oxygen content detector
Date: 2025-12-13Read: 6
Fixed oxygen content detector is an important equipment for industrial safety monitoring, widely used in industries such as chemical, metallurgical, petroleum, pharmaceutical, etc. It is used to monitor oxygen concentration in the environment in real time and prevent safety hazards caused by oxygen deficiency or enrichment. This article will provide a detailed introductionFixed oxygen content detectorThe entire process of installation, debugging, use, and maintenance is carried out to help users operate correctly and ensure the stable operation of the detector.
1、 Preparation work before installation
1. Determine the monitoring location
Installed in areas where gas is prone to accumulation or leakage, such as tank storage areas, near pipelines, around reaction vessels, etc.
Avoid installing in locations with strong airflow, high temperature, high humidity, or strong electromagnetic interference to avoid affecting detection accuracy.
Ensure that the installation height conforms to the gas density characteristics (such as oxygen density close to air, usually installed at a height of 1.5-2 meters).
2. Check the equipment and accessories
Confirm that the detector model, sensor type (electrochemical/zirconia), power supply mode (DC 24V/AC 220V), and output signal (4-20mA/RS485, etc.) meet the requirements.
Check if the installation bracket, screws, trachea (if there is a sampling system) and other accessories are complete.
2、 Installation steps
1. Fixed detector
Use matching brackets or screws to secure the detector to the wall or pipeline, ensuring stability and ease of wiring and maintenance.
If diffusion detection (direct inhalation of ambient air) is used, ensure that the air inlet is unobstructed; If pump suction (with sampling tube) is used, the sampling pipeline should be arranged reasonably to avoid blockage by condensed water or impurities.
2. Wiring and debugging
Connect the power and signal lines (such as 4-20mA output to PLC/alarm) according to the instructions, ensuring correct wiring and avoiding short circuits.
After power on, the detector usually performs a self check (such as LED indicator flashing, screen displaying initial values), confirms that there are no abnormalities, and then performs calibration.
3、 Usage and daily maintenance
1. Calibration and zeroing
New equipment or detectors that have not been used for a long time need to undergo zero calibration (in a clean air environment) and range calibration (standard gas calibration) to ensure accurate measurement.
It is recommended to calibrate every 3-6 months, depending on the usage environment.
2. Alarm settings and linkage
According to safety standards (such as setting the oxygen deficiency alarm value to 19.5% Vol and the oxygen enrichment alarm value to 23.5% Vol), adjust the low and high alarm thresholds and link them with sound and light alarms, fans, or PLC systems.
3. Daily maintenance
Regularly clean the sensor air inlet to prevent dust and oil from affecting the detection.
Check the battery (if any) or power supply system to ensure stable operation.
Record detection data and promptly troubleshoot any abnormalities (such as sensor aging or circuit failures).
The correct installation and use of fixed oxygen content detectors are key to ensuring industrial safety. From site selection, installation, calibration to daily maintenance, every step must be strictly operated according to the specifications to ensure the long-term stable operation of the detector and effectively prevent the occurrence of oxygen deficiency or enrichment accidents. Regular inspection and calibration can ensure that the equipment is always in the best condition, safeguarding safety production.
