A fixed combustible gas detector installation involves numerous considerations, like how far to install one, where to put it, what sort of wire to use, and other things.
1. If there is a power outage, wiring should be completed, and power should be restored after making sure that the wiring is accurate. The probe should then be debugged remotely if there is no gas leak at the location.
2. As close as feasible to the valve, pipe interface, air outlet, or other point where it is easy to leak, but not so close as to interfere with the operation of other equipment, the installation position should be within a radius of 1 meter.
3. A probe can be set up in an area of 20 to 50 square meters when used for large-area gas detection, which can result in safety monitoring.
4. Installation height: When detecting gases heavier than air, such as liquefied petroleum gas, it is installed at a distance of 1.5 to 2 meters below the ground. It is installed at a distance of about 1 meter above the roof when detecting gases lighter than air, such as hydrogen, natural gas, city gas, etc. Incorporate about meters.
5. There are several installation techniques, including pipe tying, wall hanging, and roof hoisting. Make sure the installation is solid and trustworthy. For easier operation and troubleshooting, we have an infrared remote control.
6. Pipes should be utilized for the on-site wiring, the pipes used should meet fire protection standards, and the pipes should be connected with probes to meet fire protection standards.
7. The sensor must be placed downward during installation.
8. When wiring, shielded cables should be used. A single wire has a diameter bigger than 1 square millimeter. When wiring, the shielding layer must be grounded.
9. To guarantee the instrument's accuracy in detection, calibration is advised once a year.
10. Only a 4-20ma signal, which can be connected to the split-line system's mainframe, can be output by the probe without a display. The probe with a display, display, and alarm can produce an RS485 or a 4-20 mA signal. It may be linked to either the bus system host or the split line host. Three-core or two-core lines are used by the split line host. Every probe must be linked directly to the host; the bus system host is a four-core wire that can be connected in parallel, making wiring much more practical when there are several probes.
