Electrochemical Sensor - an overview | ScienceDirect Topics

In electrochemical sensors the target gas interacts with an electrolyte causing electrochemical reactions which produce a current. This current is dependent upon the concentration of the target gas (by either a linear or logarithmic relationship) and can be measured. Currently in-use models of electrochemical sensor include the Alphasense D-4 mini and the OMC-1108. In comparison to the MOS ...

Druckmessgerät – Wikipedia

Ein Druckmessgerät (auch Manometer – von altgriechisch μανός manós „dünn“ und μέτρον métron „Maß“, „Maßstab“) ist eine Messeinrichtung zur Erfassung und zum Anzeigen des physikalischen Druckes eines Mediums (Flüssigkeit, Gas).. In den meisten Anwendungen wird der Relativdruck gemessen – also bezogen auf den atmosphärischen Luftdruck.

Ultraviolettstrahlung – Wikipedia

Ultraviolettstrahlung, kurz UV, UV-Strahlung, UV-Licht oder Schwarzlicht, ist elektromagnetische Strahlung im optischen Frequenzbereich mit kürzeren Wellenlängen als das für den Menschen sichtbare Licht. Jenseits der UV-Strahlung schließt die Röntgenstrahlung an. Die Farbwahrnehmung violett entsteht durch die kürzesten noch mit dem Auge wahrnehmbaren Wellenlängen.

LogiDataTech - Gassensor & Messprinzipien

· A gas sensor is a device which detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and concentration of the gas can be estimated. MQ-6 Gas Sensor ...

Vacuum Sensors Selection Guide | Engineering360

Vacuum sensors are used to measure vacuum or sub-atmospheric pressures. Vacuum means pressure below atmospheric. Since true vacuum is never attained, the measurement is in respect to a near absence of gas pressure. Vacuum can be measured using a conventional pressure sensor; however they typically do not resolve extremely low concentrations of ...

NOx Sensors - DieselNet

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 convert the NOx concentration in the functional layer into an electric signal, the functional layer is supplied with an ...

Gas sensor Wikipedia

Gas sensor. A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals. Gas detectors can be ...

What is a Sensor? Different Types of Sensors, Applications

· Gas Sensors are more common in laboratories, large scale kitchens and industries. They can detect different gases like LPG, Propane, Butane, Methane (CH4), etc. Now-a-days, smoke sensors (which often can detect smoke as well gas) are also installed in most homes as a safety measure. The “MQ” series of sensors are a bunch of cheap sensors for detecting CO, CO2, CH4, Alcohol, …
