Product Detail
1.Domestic, Industrial spot natural gases,LPG, coal gas,combustible gas detection stable function 2.fast response 3.mini size

Hot-wire type gas sensor

MR511 type gas sensor through gas absorbtion on the metal oxide semiconductorgenerates hot conduction and electronics conduction change principal, the white coilresistor change when detecting gas concentration. MR511 consists detecting elementand compensation element, both elements are placed in a wheatstone bridge circuit,when the combustible gas appears, the detecting element resistor reduces, bridge circuitvoltage output changes, the voltage will increase according to the gas concentrationincrease, the compensation element refers to temperature compensation effection.

FeaturesHigh sensitivity, large outputFast primary stability time, quick responseRemarkable reproducibility and reliability.Goode selectivity, avoid smoke ethanol disturbLow consumption, miniature designApplicationsDomestic, Industrial spot natural gases, LPG.COAL GAS, alkyl etc combustible gasconcentration detection.Combustible gas leak alarmCombustible gas detection
