Because the internal circuit board is provided with a latest single chip microcomputer and a high-integration digital circuit and the shells are made of high-intensity stainless steel, the methane sensor disclosed by the utility model has sensitive, precision and firm detection performance.
Description
Technical field
The present invention relates to methane detector device field, refer more particularly to a kind of methane transducer.
Background technology
Mine safety is that China pays close attention to and urgent problem always, the collection in colliery is produced and is faced with many difficulties, particularly colliery can produce a large amount of flammable explosive gas in process of production, in recent years, mine safety explosion accident frequently occurs, huge economic loss and casualties are caused, and cause the pollution of environment, along with gas detection sensor moves in coal production, Safety of Coal Mine Production has obtained certain change, methane is the gas of no color or smell, only have by sensitive reliable detecting instrument and just can detect, methane transducer can detect the variation of methane concentration, and record and be transferred to alarm, in the time reaching certain numerical value, alarm can start warning device, avoid the generation of accident, the detection methane concentration variation range of existing sensor is wide not, the shell resistance to impact of sensor is strong not.
Utility model content
Problem to be solved in the utility model be to provide one sensitiveer, accurately, methane transducer firmly.
For addressing the above problem, the utility model proposes methane transducer, comprise sensor fore shell, sensor back cover, sensor handle, sensor reading screen, alarm lamp, sensor label, sensor circumscription socket, warning jingle bell, sealing rubber ring, sensor detecting device and sensor internal circuit board, described sensor front and rear casing is that high-strength stainless steel material is made, described sensor internal circuit board assemblies is set up and is formed by New Type of Chip Microcomputer and high integrated digital circuit, described internal circuit board is embedded in the middle of sensor fore shell and sensor back cover, described sealing rubber ring is embedded in the gap of sensor fore shell and sensor back cover, described sealing rubber ring is dustproof and waterproof sealing rubber ring, described sensor detecting device is by high concentration methane sensing chamber, low-concentration methane sensing chamber, methane inlet plenum composition, the top of described sensor housing is provided with sensor handle, sensor handle is connected with sensor fore shell upper end by the mode of bolt, described sensor reading screen is connected with sensor internal circuit board assemblies by electrical connection, described alarm lamp is connected by electrical connection with sensor internal circuit board assemblies, the alarm lamp group that described alarm lamp is made up of High brightness Red LED, described warning jingle bell is connected by electrical connection with sensor internal circuit board assemblies, described warning jingle bell is piezoelectric ceramics, described sensor detects mouthful device and is connected with sensor internal circuit board assemblies by electrical connection.
The utility model GJ-40 colliery with the beneficial effect of the dense methane transducer of height is: the utility model is state-of-the art single-chip microcomputer and high integrated digital circuit because internal circuit board adopts, and shell adopts high-strength stainless steel to be made, thus have sensitiveer, accurately, firmly detect performance.
