Tehnički princip od plin detektor
Gas detektor is a specijalizirani instrument za plin safety koncentracija detekcija, its working princip is uglavnom kroz the gas senzor akvizicija fizički ili kemijski neelektrični signali into električni signali into električni signali, i then through the external circuitry of the the above electric signals rectification, filtering and other processing, i through these processed signals after the control of the corresponding module to achieve the detection of gas. Međutim, the core of the the gas detector is In Sensor Components, it Is Based on The Detection of Different Gases, The Distinction Between The Detection of Technical Principles are Not The The Same, Such As Gas detektor Common Technical Principles of Catalytic FLAION, ELECTROkemijski, infracrveni, PID, TO Vodljivost, optički Waveguide i Other Principles, That The Partners May Know What Are The Functional karakteristike of the differences between them?
1. Katalitički izgaranje tehnologija princip
Catalytic izgaranje plin detektor tehnologija princip, it is the use of Wheatstone most princip, by the detection element and kompenzacija element element uparen sastav of the most arm, plamena izgaranje događa on the Surface of The Surface of The Flesh of The Detection element when Encountering Flammable gases, The Sensitive Body Temperature Rises, The Resistance of The Temperaturno Sensitive Material Increases, The Most Output voltage postaje veći, The Voltage Change With The Increase In The Concentration of The Gas and The Increase Is Proportional to The Increase In The Measurement of The Bridge Output Signal. According to the measurement of the most out signal, the size the the change can be determined to detect the koncentra of the gas.
2. Poluvodič tehnologija princip
Semiconductor gas detektor tehnologija princip, which uses the adsorption of the measured gas to change the vodljivost of the poluvodič, the the struje changes the the comparison of excitation alarm circuit. Semiconductor type sensors are most astil by the environment when measureding, so the out linearity is not stable. Semiconductor sensors are now widely used in the field of measure the micro-leakage phenomenon of of plinovi due to njihov vrlo osjetljiv odgovor.
3. Elektrokemijska tehnologija princip
Electrochemical gas detektor, it is through the sensor and the measured gas reaction and produce and gas koncentracija proporcionalno to the electric signal to work. The measured gas first reacts with the sensor through tiny capilar-type otvori, then a water-repellent barrier, and finally reaches the electrode surface. A moderate amount of gas is next allowed to react with the sensing electrode to form an adequate electric signal while preventing electrolyte leakage from the sensor. The gas diffusing through the barrier reacts with the Sensing electrode, which can be ili oksidacija or smanjenje.
4. Infracrveno tehnologija princip
Infracrven gas detektor tehnologija princip, it is based on Lambert-Beer law, the physical law is when a beam of parallel monochromatic light perpendicular to a uniform non-scattering light-absorbing material, its absorbance and light-absorbing material koncentracija i the thickness of the absorbing layer is proportional to. Infracrven gas detektor obično korišten infracrven valna duljina of 2 ~ 12μm, simply put, infracrveno gas detektor princip je to be mjereno kontinuirano kroz a certain length and volume of the container, from the container can be transmittance of light in the two end faces of an end face of the side of a beam of infrared light, and then in the other end of the the of the the of the of infracrven radiation intenzitet, i konačno based on the infracrven apsorpcija i the koncentra of of svjetlosno-apsorbirajući materijali Konačno, based on the infracrven apsorpcija i the koncentracija of svjetlosno apsorbiraju tvari je proporcionalno to veličina of the the koncentracija of the measured gas can be poznato.
5. PID tehnologija princip
Light ionization PID gas detektor tehnologija princip, it is a a UV light source, chemical substances in its excitation to produce positive and negative ions can be easy detected by the detector. When molecules absorb high-energy ultraviolet light, ionization occurs, molecules in this excitation produces negative electrons and constitute positive ions. The current generated by these ionized particles is amplified by the detector, and the concentration in ppm level is visible on the surface. These ions pass through the the electrodes and quickly recombine together into the original organic molecules. The molecules are not damaged in this process.
6. Toplina provodljivost tehnologija princip
Termalna vodljivost plin detektor je a nova tip of zapaljiva plin detekcija princip, it is uglavnom kroz the measurement of the amount of change in the thermal vodljivost of the gas smjesa to real the analysis of the koncentracija of the gas being measured. Obično the razlika in termal vodljivost of termal vodljivost of the gas senzor through the circuit is converted into a change in resistance, the the traditional detection method is to send the gas to to bosti TO ATH OP OP=The Centar The The Gas Chamber A A Heat-Sensitive element, Such As Thermistor, Platinum Or Tungsten Filament, Heated To A Certain Temperature, The Change In The Thermal Vodljivost of the mixed gases is converted into a change in the resistance of thermal elements, the change in the resistance value of the easier to točno measure out.
