· Figaro Engineering's description of gas sensor types; Gas sensors which can detect carbon dioxide (CO 2): MQ-135 (metal oxide semiconductor), MG-811 (electrochemical with a non-replaceable activated carbon filter), MG-812 lower voltage version of MG-811, ExplorIR-W CO2 Sensor and Telaire T6613 CO2 sensor module (Non-dispersive infrared).
Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. A Sensor converts the physical parameter (for example: temperature, blood pressure, humidity, speed, etc.) into a signal which can be measured electrically. Let’s explain the example of temperature. The mercury in the glass thermometer expands and contracts the liquid to convert ...
Common sensor types which are used in gas detectors are electrochemical sensors, catalytic sensors, photoionisation (PID) sensors, infrared sensors, galvanic sensors and semiconductor sensors. Electrochemical sensors. With an electrochemical sensor toxic gases such as CO, H2S, NH3, Cl2, NO2, SO2, etc. can be detected. An electrochemical sensor works by gas that flows into the sensor …

· These types of sensors are used for detecting carbon dioxide and a wide range of combustible gases. A photo-ionization detector or PID breaks molecules into positive and negative charged ions and measures the electrical charge of these ions using a detector to display the amount of gas or vapor that is present. These types of sensors are used ...
The gas detector sensor converts the measured variable, a gas concentration, into an electrical signal. Depending on the gas sensor type, this is achieved by either chemical or physical processes. Dräger offers a wide range of different gas detector sensors for fixed gas warning systems. Business Field. Fixed Gas Detection.
· Pellistor gas sensors (or catalytic bead gas sensors) have been the primary technology for detecting flammable gases since the ‘60s. Despite having discussed a number of issues relating to the detection of flammable gases and VOC, we have not yet looked at how pellistors work. To make up for this, we are including a video explanation, which we hope you will download and use as part of any ...
