【 Weak current College 】 gas detection system installation specification

1. fixed probe for attention?

A gas detection probes for selected points should choose valve, pipe interface, vent or easy leakage near the circumference within the range of 1 m, as close as possible to, but do not affect other equipment operations while avoiding high temperature, high humidity environment, to avoid external effects, such as the splashing water, oil and cause mechanical damage.

B gas detection probe installation method can use the roof lifting, wall mounting or holding pipe installation, ensure that the installation of the solid and reliable, while at the same time consideration should be given to ease of maintenance, calibration.

C gas detection probe wiring should adopt three core shielded cable, single root diameter greater than 1 mm square, wiring when the shield must be grounded.

D gas detection probe installation should be performed by a fixed sensors, lock nuts should be fully tightened, probe cover should be entirely covered with screw fastening with explosion-proof requirements.

E gas detection probe should be in the power case, determine the correct wiring of power after; should determine the scene no gas leakage, open end debug probe.

F the probe should be installed in a shock and temperature stability as possible also.

G gas detection probe calibration should be at least once every year to ensure measurement accuracy. Probe test against pure gas, try using a lighter Hoon is strictly prohibited, to avoid probe was about concentration of combustible gas smoked on and premature failure.

H probes from the hands of time, one year warranty, the warranty period, our company can provide paid services. As a user probe damage caused by improper use is not covered under warranty, the Visual conditions nuclear charge costs for repair or replacement.

2. gas detection system installation specification?

Combustible gas controller installation specification:

1. combustible gas controller should be installed in non-explosion-proof meter rooms, is strictly prohibited in the explosion-proof premises.

2. combustible gas controller mode regardless of the installation, you should ensure that fixed firmly to prevent vibration, dust and water, the environment should meet the instrument manual.

3. flammable gas controller should be relatively clean power, avoid large motor devices use the same power.

4. combustible gas controller should shell grounding or power plug of Earth grounding.

5. combustible gas controller shell is forbidden, otherwise it will affect the shielding effect.

Combustible gas detector installation specification:

1. flammable gas detection probes for selected points should choose valve, pipe interface, vent or easy leakage near the circumference within the range of 1 m, as close as possible to, but do not affect other equipment operations while avoiding high temperature, high humidity environment. Pressure insulation Tester grounding resistance Tester leakage current Tester Creepage switch Tester transformer meter high pressure table leakage circuit breaker test zinc oxide arrester loop impedance testers multi-function Tester

2. flammable gas detection probe for large gas detection can take 10 to 12 square meters a probe layout, you can also reach the detection alarm effect.

3. flammable gas detection probe installation method can use the roof lifting, wall mounting or holding pipe installation, ensure that the installation of the solid and reliable, while at the same time consideration should be given to ease of maintenance, calibration.

4. combustible gas detector installation height: detection of hydrogen, natural gas, town gas, and other specific gravity less than air gases, using distance roof 1 meters installed; detection of LPG isobaric is greater than the air gases, using distance ground 1.5 ~ 2 meters installed.

5. combustible gas detector wiring should adopt three core shielded cable, single root diameter greater than 1 mm square, wiring when the shield must be grounded.

6. flammable gas detection probe field alignment should wear a pipe, the pipe shall be consistent with the fire requirements, pipe and probe connected to meet fire protection requirements.

7. flammable gas detection probe installation should be performed by a fixed sensors.

8. flammable gas detection probe should be in the power case, determine the correct wiring of power after; should determine the scene no gas leakage, open end debug probe (for flameproof probe SP-1102).

9. combustible gas detector calibration should be at least once every year to ensure measurement accuracy.
