Principle
The detector uses the pump-suction Sampling method, and the environment gas is sucked into the detection gas path by the built-in micro-sampling pump. After the gas is pretreated, it reaches the infrared NDIR Sensor at the core. Based on the principle of non-dispersed infrared, the Sensor calculates the gas concentration by measuring the Absorption intensity of sulfur hexafluoride gas to specific wavelengths of infrared light. A 32-bit ARM processor inside the instrument processes the Sensor signal, combining temperature and pressure compensation algorithms, and finally displays the exact concentration value on the screen, and triggers an alarm when the limit is exceeded.
Applications
Sulfur hexafluoride gas leak detection, power industry (such as GIS switch station, substation), confined space operation safety monitoring, environment monitoring, industrial process control
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 displays the gas concentration in real time.
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 setting: zero-point calibration, multi-point calibration or setting alarm parameters through self-programming function as needed.
7. Shutdown: After the detection is completed, press the power button to shut down.
Notice
• Please use within the range of Ambient Temperature (-30~ 50 ℃) and Humidity (10~ 95% RH without condensation) specified by the instrument.
• Avoid long-term use in strong electromagnetic interference, corrosion gas or high concentration dust environment.
• Regularly calibrate the instrument to ensure detection accuracy.
• The instrument has the function of automatic cleaning of the gas circuit, but it is recommended to manually clean the sampling pipeline after long-term use.
• When charging or data transmission, make sure to use the matching dedicated cable and adapter.
• Instruments are designed to be explosion-proof, but must not be disassembled or repaired in hazardous locations beyond the Explosion-proof level.
• Pay attention to the service life of the Sensor (about 3 years), and it needs to be replaced in time when it expires.
Store in a drying and cool place to avoid high temperature (over 70 ° C) or low temperature (below -30 ° C) environment.
