Infrared methane (CH4) sensor*-SJH series
Introduction
Miniature NDIR CH4 gas sensor adopts advanced non-dispersive
technology to detect and monitor CH4 concentration. It is with a
heated infrared source inside a small chamber, in this case, the
inside temperature of the gas sensor is much higher than the
outside which can avoid condensing events and the high humidity
influence .
Besides, the PCB inside the gas sensor is specially treated for
corrosion protection.
Features:
1.NDIR technology, with longlifespan
2.Diffusion sampling, compact size, easy handling
3.High precision, low power consumption, less maintenance
4.Self-compensation of temperature
5.Great resistance to moisture and other gases interference
6.Voltage output and RS**2 output are optional
7.Good sensitivity and selectivity to CH4 gas
Applications
1.Mine, metallurgy, liquefied gas station, spray paint, petroleum,
fuel gas transport etc.
2.In gas leakage detecting equipment in family and industry
3.Gas concentration meter.
4.Combustible CH4 gas leakage alarm or detection
