Thermokoppel - Wikipedia

Principe. Een thermokoppel bestaat uit twee draden van verschillende metalen of metaallegeringen die aan elkaar zijn verbonden, bij voorkeur door ineensmelting. Als er tussen beide contactpunten een temperatuurverschil heerst zal een potentiaalverschil ontstaan, waarvan de grootte afhankelijk is van het temperatuurverschil en de gebruikte metalen.

Gas Sensor - an overview | ScienceDirect Topics

Gas sensors are generally understood as providing a measurement of the concentration of some analyte of interest, such as CO, CO 2, NO x, SO 2, without at this point dwelling on the plethora of underlying approaches such as optical absorption, electrical conductivity, electrochemical (EC), and catalytic bead (see Section 3). However, and as discussed in Section 2, many other gas sensors ...

NOx Sensors - DieselNet

All HC and CO in the exhaust gas should be oxidized before the NOx sensing cell to avoid interference. Also, any NO ... In the gas sensor mode, the sensor is operated at a temperature of 650°C, where the adsorbed and the desorbed NO molecules are in balance. As a result, the sensor measures the in situ NOx value, in the ppm concentration range that is suitable for exhaust gas applications. To ...

Sensori di gas - Wikipedia

Sensori di gas elettrochimici. I sensori elettrochimici hanno fatto la loro comparsa nei primi anni ‘50 per monitorare la quantità di ossigeno ambientale. Negli anni ‘80 questi sensori hanno subito un netto processo di miniaturizzazione che ne ha consentito una prima diffusione sul mercato. Il principio di funzionamento con cui questi sensori operano fa sì che esista una proporzionalità ...

Toxic Gas & Oxygen Detectors | Gas Sensors | RC Systems

A sensor inside the toxic gas detector reads the gas levels, and when they rise above or fall below the specified level, an alarm activates. Sensors are made from electrochemical cells, and the alarm can be visual or audible. Readings can be sent via a digital signal or analog signal to a control room, and alarms can actuate local relays for the operation of alarm safety devices such as horns ...

CO sensors can become saturated with target gas CO. If enough CO enters the sensor beyond maximum range (that listed in the instruction manual), the sensor is unlikely to be able to process all applied gas. When this scenario occurs, the electrolyte becomes saturated. A saturated sensor will continue to show high gas readings until the gas can be processed from the electrolyte. If saturation ...
