Mes kontrastas trys gerai žinomi dujos detektoriai.
1. Charakteristikos puslaidininkiai jutikliai ištirti
Gas detektoriai su puslaidininkiais jutikliais are sukurtais using resistance changes. An alcohol sensor is created based on the idea that when in dioxide come into contact with alcohol gas at a high temperature, its resistance would rapid drop. This sensor is ideal for detecting civil gas because of its inexpensive cost and other features. On semiconductor sensor gas detectors, environmental conditions have a considerable impact, causeing nestabilus aptikimas rezultatai. Šis tipas of gas detektorius is taip pat netinkamas for locations kur tikslus matavimas is reikalinga nes the output parameters cannot be determined.
2. Įvertinimas degimo jutiklis savybės
On the platinum resistor's surface, the burnustion sensor create a high-temperature resistant catalyst layer. The deghable gas will catalyze and burn once the temperature is right. The platinum resistor's temperature will rise due to burning, which will also cause the resistance to reflect the degi gas concentration. The catalytic burnustion sensor gas detect comlightible gas gas; if the gas cannot be burned, jutiklis bus ne atsakys. Katalizinis degimas dujos detektorius turi a ilgas servitutas gyvenimas ir reaguoja tiksliai ir greitai.
3. Analizė tipai elektrocheminiai jutikliai
A nemaža dalis jos degios, toksiškos ir kenksmingos dujos are elektrochemiškai aktyvios ir gali būti elektrochemiškai oksiduotos arba sumažintos. The principle of the original battery type gas sensor is apytiksliai the same as that of the dry battery. At present, the detection of toxic and harmful gas daugiausia remiasi on constant potential elektrolitinis cell type gas sensoriai. Koncentracija akumuliatorius tipas dujos jutiklis skardinė forma koncentracija elektromotoris jėga susiję į dujos koncentracija ir aptikti dujos koncentracija, toks as deguonis jutiklis automobiliams.
