Infrared Technology for Hydrocarbon Gas Detection

gas detection, catalytic sensors are still the sensor of choice when it comes to operating the sensor head above 75°C. This is because of these devices can withstand and operate at much higher temperatures (up to 200°C) than the commonly used instruments in infrared technology. Also, when calibrating a unit in the field or for calibrating a unit to a different gas in the field, the procedure ...

Ultrasonic Gas Leak Detection: What is it and How Does it ...

problematic because the gas easily dilutes and drifts away from conventional gas sensors. Ultrasonic gas leak detectors solve this problem by detecting the airborne acoustic ultrasound generated when pressurized gas escapes from a leak. When a gas leak occurs, the ultrasound generated by the leak travels at the speed of sound, through the air, from the source to the detector. Ultrasonic gas ...

Calibrating and Testing Direct-Reading Portable Gas ...

· A calibration check verifies that the sensor(s) and alarms respond within the manufacturer's acceptable limits by exposing the instrument to a test gas. The operator compares the reading to the test-gas concentration (as indicated on the cylinder containing the test gas). If the instrument's response is within the acceptable range of the test-gas concentration (typically ± 10-20% of the test ...

USGBC LEED v4 EQc4 - Air Quality Assessment

for LEED testing may vary dramatically2. However, for the specific 35 VOCs recently added in LEED v4, air samples sent to a laboratory for GC/MS analysis is a clear requirement. Of course, it can be very time and cost efficient to establish that general TVOC levels are low, using a GrayWolf IAQ/LEED kit, prior to sending out air samples for expensive speciation of the 35 VOCs. In addition ...

Gas Sensor - Arduino Project Hub

· This gas sensor uses a MQ-2 gas sensor to indicate if there is gas in the area. so the sensor has a threshold value (the threshold value is around the amount of smoke in there is a fire) in that if it goes above it starts alerting people in the vicinity. The alert just shows a red led and starts beeping. This idea is very helpful and is used on a daily basis with the smoke alarms that a lot of ...

Schadstoffe in der Raumluft – Raumluftmessung mit VOC-Sensoren

VOC-Sensoren erkennen Veränderungen der VOC-Konzentration in der Raumluft. Sie reagieren dabei nicht spezifisch auf einzelne Stoffe, sondern auf VOCs im Allgemeinen und auf Gase wie zum Beispiel Wasserstoff und Methan. Die Informationen von VOC-Gassensoren können genutzt werden, um den Betrieb von Luftreinigungs- oder Lüftungsanlagen zu regeln. Steigt der VOC-Gehalt in der Raumluft, …
