Principle
The detector uses the pump-suction Sampling method, and the environment gas is sucked into the instrument through a built-in micro-sampling pump. After the gas enters, it interacts with the core infrared NDIR (non-dispersion infrared) Sensor. Based on the characteristic absorption principle of a specific gas to infrared light, the Sensor accurately calculates the concentration value of sulfur hexafluoride (SF6) gas by measuring the change of infrared light Absorption intensity. The measurement results are processed and compensated (including temperature and pressure compensation) by the built-in 32-bit ARM processor, and finally the concentration value, MAX Maximum, STEL, TWA and other information are displayed in real time on the display screen, and an alarm is triggered when the concentration exceeds the standard.
Applications
Power industry SF6 equipment leak detection, substation, gas-insulated switchgear (GIS) maintenance, sulfur hexafluoride gas production and storage sites, confined space operation safety monitoring, environment monitoring
Steps
1. Boot warm-up: Press the power button for a long time to turn it on, and the instrument will warm up for about 30 seconds.
2. Select detection mode: Select "normal detection mode" or "patrol mode" through the menu.
3. Set the sampling pump gear: according to the detection needs, select the low, medium or high Sampling flow rate.
4. Detection: The sampling tube is inserted into the area to be measured, and the instrument automatically samples and displays the real-time concentration.
5. Data viewing and export: You can view historical data through the menu, or connect to a computer through the USB interface to export data.
6. Calibration and settings: According to needs, zero-point calibration, multi-point calibration or alarm parameters are set through the menu.
7. Shutdown: After the detection is completed, press the power button for a long time to shut down.
Notice
Make sure the instrument is fully charged before use.
• Avoid working for long periods in extreme temperatures (below -30 ° C or above 50 ° C) or high Humidity (above 95% RH) environments.
• The instrument is designed to be explosion-proof, but it is strictly forbidden to disassemble or charge in dangerous places.
• Sensors are calibrated regularly to ensure detection accuracy.
• The sampling tube should be kept clean and open to avoid clogging affecting sampling.
• When the instrument alarms, evacuate to a safe area immediately and identify the cause.
• Please store in a drying and cool place to avoid direct sunlight and violent vibration.
• Non-professionals should not disassemble or repair the instrument by themselves.
