MZ-2 type combustible gas detector
Combustible gas detection alarm instrument is mycompany development and production of new gasdetection instrument, its outstanding characteristic is theprinciple of catalytic sensor, intelligent signal processing system, a storage, the function of reading data. The instrument has the advantages of wide measuring range,long service life, high accuracy, simple operation, the product is suitable for combustible gas detection in ambient air (hydrogen, methane, propane, butane,pentane, alkyne, alkene, etc.) or organic vapors(gasoline, alcohol, methanol, xylene and other organic solvents) concentration, over the years has been widelyused in oil exploration, oil and gas transportation, oil refining, metallurgy, power, chemical, oil, liquefied gas station, mine, tunnel, tunnel, underground pipelines and other places, to effectively prevent the occurrence of theaccident of burning, explosion accident. This machine isintrinsically safe explosion-proof, explosion-proof symbol is ia II CT3.
Characteristic
High performance sensitive element 1, advanced
2, excellent accuracy and good repeatability
3, SMD assembly process, stable and reliable performance
4, artificial intelligent microcomputer control
5, the backlight of large screen LCD digital, word graphdisplay
6, portable, compact and lightweight design
7, two - sound, light alarm
8, smart energy saving design, low battery indicator
Working principle
Sensor to diffuse directly with the gas responsemeasured in the environment, the voltage signal is generated linearly. The signal processing circuit is composed of a plurality of integrated circuit with a smart chip based. The sensor output signal through the filter amplifier, analog to digital conversion, model calculation,processing, display the concentration of measured gasvalue on the LCD screen. The instrument can be set two alarm, when the gas concentration reaches the alarm value preset, the instrument will alarm level according todifferent, sends out the different frequency sound, light alarm signal. Instrument indicator light flashes once at intervals of about 10 seconds, said instrument works.When the battery voltage to a certain extent, charging,display screen will appear under pressure marks,prompting the user charge.
