Semiconductor-type gas sensor can be efficiently used for：Methane, ethane, propane, butane, alcohol, formaldehyde, an oxidation
Detect many gases such as carbon, carbon dioxide, ethene, acetylene, vinyl chloride, styrene, acrylic acid.Its less stable, by ring
Border influence is larger；Especially, the selectivity of each sensor is not unique, and output parameter can not be determined.Therefore, it is unsuitable
Place applied to accurate measurement requirement.
Combustion-type sensor is to prepare resistant to elevated temperatures catalyst layer on the surface of platinum resistance, at a certain temperature, can
Combustion property gas burns in its surface catalysis, and burning is the rise of platinum resistance temperature, and resistance variations, changing value is that imflammable gas is dense
The function of degree, it is in the range of imflammable gas, non-selectivity.Dying fire works, and has the danger for blast of igniting.Most elements have
Machine steam has intoxication to sensor.
The effect of oxygen sensor is to determine the whether superfluous information of oxygen in the exhaust after engine combustion, i.e. oxygen contains
Amount, and oxygen content is converted into voltage signal is delivered to computer in the engine, enable the engine to realize with excess air because
Number is the closed-loop control of target；Ensure that three-way catalytic converter is closed to the hydrocarbon in exhaust, carbon monoxide and nitrogen oxidation
Three kinds of pollutants of thing have the transformation efficiency of maximum, the conversion and purification farthest discharged pollutants.
Because oxygen sensor is only in high temperature, end reaches more than 300 °C, and its characteristic can just be fully demonstrated, ability
Output voltage, therefore, current oxygen sensor do not reach constant temperature, cause the conversion that can not be discharged pollutants well and
Purification.
The content of the invention
The purpose of this utility model is to close there is provided a kind of simple in construction, design for the defect and deficiency of prior art
Reason, thermostatic type lambda sensor easy to use.
To achieve the above object, the technical solution adopted in the utility model is：It includes shell, heater, zirconium oxide
Measurement pipe, thermocouple, air conduit, smoke tube, ceramic filter, air flow division board, thermostat, flue furnace wall；Institute
The shell stated is arranged in flue furnace wall, and one end of shell is provided with zirconium oxide measurement pipe, and the periphery of zirconium oxide measurement pipe is set
There is heater, the side of heater is provided with thermocouple, and the other end of shell is provided with air flow division board；Described
One termination fresh air of air conduit, the other end of air conduit is set inside the housing；One end of described smoke tube
Ceramic filter is connected with, flue gas enters smoke tube, the other end and cage connection of smoke tube through ceramic filter；It is described
Heater on be connected with thermostat.
Preferably, described heater is electric furnace heating wire heater.
Preferably, described air conduit and smoke tube is made of aluminum oxide.
Reference gas are passed through when the utility model is operated, inside zirconium oxide measurement pipe --- air, it is outside then flow through and passed through
Filtered tested gas --- the flue gas of ceramic filter, ceramic filter is mainly used to filter out flue dust, powdered carbon in flue gas etc.
Impurity particle, and damping action can be played to signal, prevent pointer from shaking.
After said structure, what the utility model was produced has the beneficial effect that：Thermostatic type oxygen described in the utility model is passed
Sensor, end is up to more than 300 °C of constant temperature, normal output voltage, the conversion and purification farthest discharged pollutants,
The utility model have the advantages that it is simple in construction, set rationally, low manufacture cost.
