基礎 知識 の 分析 の 可燃性 ガス 検出器
It should be noted that gas detection is increasely valued by people in our daily lives, and the results of detection are also of great concern. You should know that this can have a great impact on our personal health. A gas detector is an instrument that detects gases, mainly relying on a sensor at the port to sense toxic and harmful gases, in order to achieve the purpose of alarm. most ガス 検出器 are mainly used for industrial and environmental monitoring. Let's take a brief look at the monitoring of gas detectors in industry.
可燃性 ガス 検出器 は a ガス 濃度 検出 計器 that integrates a gas detector and a gas alarm controller. The gas detector can be directly powered by a 220V power supply. The toxic gas detector uses imported electrochemical/catalytic combustion sensors, which have the advantages of stable signal and high precision. The explosion-proof wiring method is suitable for various dangerous places. Its product features: 1. 高度 マイクロプロセッサ technology for combustible gas detectors; 2. Range specifications can be determined by users according to actual requirements; 3. 220V Ac AC power supply; 4. On site concentration display, sound and light alarm; 5. Fast response speed and high measurement accuracy; 6. The output signal can be determined by the user according to actual requirements; 7. Relay output (任意) RS485 bus output (任意)。
In addition, for the detection principle of combustible gas detectors, catalytic combustion/electrochemical detection method, diffusion working method, long-term continuous operation output signal relay output or RS485 output (optional) wiring method, model RVVP3 1.0mm2 structural material, die cast aluminum explosion-proof mark Ex dIICT6 protection level IP65, working humidity 90% RH, working temperature -20-50 degree (special requirements depending on needs). Combustible gas detectors belong to national mandatory calibration measuring instruments and are widely used in industries such as metallurgy, petroleum, chemical, petrochemical, coal, as well as municipal gas, storage, transportation, hotels and fire departments.
いつ 可燃性 または 有毒 ガス 漏れ で 環境 および ガス 濃度 到達 爆発 または 中毒 クリティカル ポイント セット によって 検出器, 可燃性 ガス 検出器 意志 放出 an alarm signal to remind workers to take safety measures to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production. Due to the normal use of the detector sensor, its sensitivity naturally decreases by 10% to 30% every year. If the sensitivity of the the detector sensor decreases, and the the leaked gas concentration reaches the lower explosive limit without timely alarm, there will be a risk of explosion. Therefore, combustible gas detectors need to be calibrated regularly every year to ensure the accuracy and reliability of their performance and measurement values.
