Combustible gas detector basic knowledge analysis
To know our life for gas detection is more and more by people's attention, at the same time for the results in the test is also quite concerned. To know that this can be for our personal safety has a great relationship. Gas detector a detection of gas safety instrumentation, which relies mainly on the sensor sensor at the port of the device to sense toxic and harmful gases, so as to achieve the purpose of the alarm. Most of the gas detector is mainly used in industry, environmental monitoring. Here we will briefly understand about the gas detector in the industrial monitoring.
Combustible gas detector is a gas detector and gas alarm controller as one of the gas concentration detection instruments, gas detector can be directly powered by 220V power supply, toxic gas detector using imported electrochemical / catalytic combustion sensors, with stable signals, precision and other advantages of the explosion-proof wiring suitable for all kinds of hazardous places. Its product features: 1, combustible gas detector advanced microprocessor technology; 2, range specifications, the user can be based on actual requirements; 3, 220V Ac AC power supply; 4, on-site concentration display, sound and light alarm; 5, fast response time, high measurement accuracy; 6, the output signal The user can be based on actual requirements; 7, relay output (optional), RS485 bus output (optional). Output signal: relay output (optional), RS485 bus output (optional).
In addition for the combustible gas detector detection principle catalytic combustion / electrochemical detection mode diffusion mode of operation long-term continuous operation output signal relay output or RS485 output (optional) connection mode Model RVVP3 1.0mm2 structure material die-cast aluminum explosion-proof marking Ex dIICT6 protection level IP65 working humidity 90% RH working temperature -20 ~ 50 ℃ ( Special requirements as needed). Combustible gas detector belongs to the national mandatory calibration measuring instruments, widely used in metallurgy, petroleum, chemical, petrochemical, coal and other industries and municipal gas, warehousing, transportation, hotels and restaurants and fire departments.
When the environment of combustible or toxic gas leakage, the gas concentration reaches the detector set the threshold of explosion or poisoning, combustible gas detector will send out an alarm signal to remind the staff to take measures to prevent the occurrence of explosions, fires, poisoning accidents, so as to protect the safety of production. As the detector sensor in normal use, its sensitivity naturally declines 10% to 30% per year, if the detector sensor sensitivity declines, the leaking gas concentration reaches the lower explosive limit and fails to alarm in time, it will produce the risk of explosion. Therefore, the combustible gas detector detector needs to be calibrated regularly every year to ensure that its performance and the accuracy and reliability of the value.
At the same time for the gas detector gas sensors in industrial applications are mainly used in the petrochemical industry to detect carbon dioxide, nitrogen oxides, sulfur oxides, ammonia, hydrogen sulfide and chlorine and other harmful gases; semiconductor and microelectronics industry to detect organic solvents and phosphorous alkanes, and other highly toxic gases; the power industry to detect the hydrogen produced during the deterioration of the power transformer oil; the food industry to detect the freshness of meat and other perishable food. Automobile and kiln industry to detect oxygen in the exhaust gas, in order to control combustion, to achieve energy saving and environmental protection double target; highway traffic detection of ethanol gas concentration in the breath of the driver, to prevent drunken driving, reduce traffic accidents. With the progress of the times, I think the use of gas detectors will become more and more widespread, the future will be more inestimable!
