6) Combustible gas detection system 燃气检测系统补充资料:可燃气体检测仪 分子式:CAS号:性质:一种用于检测可燃气体的仪器。它的敏感元件是表面涂敷活性催化剂的加热丝,当可燃气体与加热丝相接触时就引起接触燃烧,燃烧产生的热量使加热丝的温度发生变化,从而改变了加热丝的电阻值,使检测仪的输出值也随之变化。现在...
Because of the constant danger of explosion in these situations, any combustible gas detection system must be highly reliable as well as simple to operate and maintain. Calibration should be easy and error-free. Detectors should support both catalytic bead and infrared sensors and allow the user ...
To develop an appropriate strategy for the implementation of a combustible gas detection system, a basic understanding of the properties of combustible materials is necessary. In our discussion we will identify the general properties necessary for determining a material’s hazardous potential, then turn...
The utility model relates to a combustible gas detection and monitoring early warning system for an inspection well, which comprises a main frame and an explosion-proof tank connected with the main frame by an explosion-proof cable, wherein the main frame is fixed on the ground and connected ...
supports displaying of the gas concentration. This product is used to detect both the toxiccarbon monoxide gas and combustible gas (such as liquefied petroleum gas, natural gas,CH4(methane), etc). When trigger the detector, it will alarm with build-in siren...
Detection principle: Collect standard 4~20mA signal input or RS485 communication input (optional), analyze and display the current gas concentration of each channel, and operate related alarm signals, and transmit the information to the computer thro...
