Analysis of the basic knowledge of combustible gas detectors
To know our life for the gas detection is more and more by people's attention, at the same time for the results in the detection is also quite concerned. To know that this can be for our personal safety has a great relationship. Gas detector a detection of gas instrumentation, which relies mainly on the sensor sensor at the port 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 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 instrument, gas detector can be directly powered by 220V power supply, toxic gas detector using imported electrochemical / catalytic combustion sensor, with stable signal, high precision, 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
In addition for the combustible gas detector detection principle catalytic combustion / electrochemical detection mode diffusion working mode long-term continuous work output signal relay output or RS485 output (optional) connection mode Model RVVP3 1.0mm2 structure material die-casting aluminium 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, transport, hotels and restaurants and fire departments.
When combustible or toxic gas leakage in the environment, the gas concentration reaches the explosion or poisoning threshold set by the detector, the combustible gas detector will send out an alarm signal to remind the staff to take safety measures to prevent the occurrence of explosions, fires, poisoning accidents, so as to ensure safe production. As the detector sensor in normal use, its sensitivity naturally decreases by 10% to 30% per year, if the detector sensor sensitivity decreases, the leaked gas concentration reaches the lower limit of explosion and fails to alarm in time, the danger of explosion will arise. Therefore, the combustible gas detector detector needs to be calibrated regularly every year to ensure the accuracy and reliability of its performance and value.
