Where you permanently mount a carbon dioxide transmitter depends on why you are monitoring indoor air quality. There are 3 places it can be mounted: Indoor Air Quality: In most homes or offices, wallmounted CO2 level transmitters are used to monitor carbon dioxide levels as they would be experienced by occupants. They can be located at the same height (48 inches or 122cm is standard) and on the …

Gas Detection Sensor Mounting Height and Location Guidelines: It is important to mount the gas detection heads in areas that are most likely to first be exposed to a gas leak, or that are most representative of the gas levels in the area being monitored. Here are some criteria to consider: Density of the gas: When detecting for LEL levels of gases and vapors, the density of the gas should be ...

For this reason, the CO2 sensor unit should be mounted no higher than 1218 inches (4560 cm) above the floor. The next consideration is power. While our CO2 Safety Monitors use a 110220 VAC 50/60 Hz to 12VDC power, a 24 VDC hardwired power option is available if normal wall power is not readily available. The important thing to remember is ...

the optimal sensor mounting height in a fixed gas detection system. 1. Rule of Thumb In the absence of other rules, select a mounting height based on the anticipated location of the gas. Follow the criteria below to determine where the gas can reasonably be expected and where to place the sensor as a result. • For gases lighter than air (, Methane, Hydrogen, Ammonia), mount sensors near ...
Gas Detection Sensor Mounting Height and Location Guidelines: ... For these gases it is best to mount the sensor within inches of the floor. Lower density gases such as hydrogen or natural gas are lighter than air and will tend to collect near the ceiling. For these gases, it is best to install the sensor within inches of the ceiling. Toxic gases: Where safe breathing levels are the main ...
CO2 sensing technology by IR (infrared) is stable and is not subject to the shortterm, random drift found in air quality sensors. Most IR carbon dioxide sensors only measure CO2. A CO2 sensor is designed to control the ventilation rate in occupied spaces. People are the principal source of CO2 in indoor air. Whereas outside air carbon dioxide levels tend to be relatively low and constant, an indoor CO2 …

What should the mounting height of the sensors be? The sensor mounting height depends the type of application and on the density of the gas relative to air. Heavier than air gases should typically be detected 6 inches from the floor, lighter than air gas sensors should typically be placed on or near the ceiling, and gases which have a density close to that of air should have sensors installed in the …
Recommended mounting height for Carbon Monoxide (CO) gas detector. is m above floor. Nitrogen Dioxide (NO2) gas is heavier than air and sinks in the air.

Fig. 3: comparison of measurements from a VOC sensor and a CO2 sensor operating simultaneously in a meeting room used by multiple people for several hours In Figure 3, the CO2 sensor has completely missed times during which the VOC sensor indicated degraded air quality, which might have been due for instance to the use of cleaning chemicals dur
Therefore, when mounting a gas safety alarm you should to mount the sensor at a height closer to where the gas will be sensed first. You can do this by knowing the weight of your target gas relative to the air in the room. Below is a chart listing the molecular weights of various gases. Note that the molecular weight of fresh air is approximately Gases with higher molecular weights will ...
