Theseriesof **5main line gas detection alarm
systemadoptsnon-standard agreement or MODBUS protocol for
data collection and transmission. The intelligent
transmitter nodeacquisitioncollects and detects
the gas concentration on the
spot, The host
roundtests various nodeswith intelligent
background software, andmonitoring the gas concentration
changes inreal-time . Our product uses
the bus-system ,havingstrong anti-jamming capability, convenient
layout and simple
wiring. At the same
time, italso
providesan
controllingexternal
device (exhaust fan, solenoid valve, etc.) of the switch
output. The
detector detectsgas
concentration withnatural diffusion mode,
whichuses the imported
sensors andhas a goodsensitivity
andrepeatability. This
instrumentusesthe embedded microcontroller control
technology, simplemenu operation , complete
functions andhigh
reliability . Bus-systemgas detection
transmitter adoptsaluminum shell
material with high strength, heat
resistance andcorrosion
resistance.Ourproduct is suitable for the detection of
poisonous and harmful, inflammable and explosive gas in the
airand has been widely used in metallurgy, power plant,
chemical industry, mine, tunnel, tunnels, underground pipeline and
other places, effectively preventing the happening of the
accident. Basic parameters: Size：**4 mm * **0 mm * *4
