Volatile Organic Compound, Carbon Dioxide, Carbon Monoxide and Nitrogen Dioxide sensors should be mounted 3 to 5 feet ( to meters) above the floor level. Refrigerant sensors should be mounted 18 inches (45 cm) above the lowest level of the equipment’s location.
With the Polytron 7000 remote sensor adaptor and lead it is possible to mount the sensor up to 30 metres from the polytron 7000 transmitter. This enables the user to read and operate the transmitter from a safe area, or detect toxic gasses and oxygen levels in difficult to reach areas, whilst still being able to view and configure the Polytron 7000 from a convenient location.

Recommended Sensor Mounting Height . While the mounting height of CO sensors is often times mandated under building codes, nitrogen dioxide (NO 2) sensors have no standard, regulated mounting deciding where to mount NO 2 sensors, it is dependant on the application and the environment involved.. The density of nitrogen dioxide is greater than that of air, indicating that sensors ...
plug-in catalytic and infrared sensor cartridges. The catalytic sensors measure flammable gases in the range 0-100%LEL and the infrared sensors measure Hydrocarbons in the range 0-100%LEL, or Methane 0-100%LEL (or 0-5%Vol) and CO 2 0-5%Vol. See the specifications section for full details of the MPD sensor. The XNX EC sensor is also a serviceable stainless steel sensor with a wide range of ...
Consideration should be given to accessibility for calibration when locating sensors. For example, a sensor mounted 30 feet off the floor will be difficult or even hazardous to service. Some applications may require the sensor to be mounted at a different height than indicated below.

The CozIR®-LP3 is designed to run fully autonomously with automatic self-checking and auto-zeroing, enabling the sensor to operate for long periods with no user ...
2020-01-15· CO2 detection is required instead of ammonia detection in refrigerated and process areas. Detection system design and output functions are similar with the difference being the CO2 sensor selected, warning setpoints at % (OSHA 8 hour TWA) and alarm setpoints at %. One controller can support a combination of ammonia and CO2 sensors. One ...

2019-01-08· The most common gas sensors used in HVAC systems are oxygen (O 2) and carbon dioxide (CO 2) sensors. Ambient air is comprised of roughly 21% O 2 and just % CO 2, but a lack of indoor air circulation can dramatically skew the gas composition towards O 2 depletion and CO 2 enrichment. Indoor air quality (IAQ) is a critical factor for our health and wellbeing, and variations in …
Sensor Mounting Height There is much confusion in the industry concerning the best height to mount ammonia sensors. This is because there are valid reasons for different heights. Codes simply say “locate where refrigerant from a leak is expected to accumulate”. Ammonia vapor is lighter than air so vapor leaks will rise to the ceiling in normal conditions. A liquid leak will drop to the ...

Always determine the following before mounting: ... Temperature · Room Temperature Room sensors 24 Install sensors at a height of m in occupied spaces, and at least 50 cm from the adjacent wall. Do not install where sensor will be exposed to direct solar radiation. Always use a thermally-insulated backing when fitting to solid walls (steel, concrete etc.) Temperature · Room 25 Do not ...
The DGS-IR sensor head is sensitive to shock – special attention ... Correct mounting height according to definition in Mounting. LED status – see DGS trouble shooting. Functional test (for initial operation and maintenance) Functional test is done by pressing the test button for more than 8 sec and observing all connected outputs (Buzzer, LED, Relay connected devices) are working properly ...
Sensors should be located near the floor for gases or vapors three or four times heavier than air. They should be installed near the ceiling or roof to detect lighter-than-air gases. DON’T. Don’t place sensors near entrances or fresh air vents during representative room sampling, as sample concentrations will be diluted by incoming air. Don’t mount the detector on a surface subject to ...
If the ceiling height is higher than 10 feet, example; for heavy equipment, the carbon monoxide monitors are installed at 3 to 5 feet (1 to meters) from the floor as per the requirements of the building code regulations and the nitrogen dioxide monitors should be installed at 50% of the ceiling height and above the vehicle height to be in the open circulation of the air.
Indoor Air Quality: In most homes or offices, wall-mounted 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 same wall as you would mount a thermostat.
2018-02-26· Wherever compressed CO2 is stored, especially in confined spaces like pub cellars CO2 safety alarms should be mounted 18 inches (45cm) off the floor. Because carbon dioxide is heavier than air, it will fill the enclosed cellar space from the floor up. Depending how bad the leak is, but if say a safety valve on a primary regulator is blowing off intermittently in a small cellar or room, CO2 ...

For vehicle exhaust applications that include diesel exhaust, CO and NO 2 sensor combination gas detectors should be used to monitor the hazardous gas levels in the enclosed space.. CO is about the same density as air and will readily disperse throughout an area where there may be some air movement and activity, remaining in the breathing zone (4-6 ft from the floor).
2020-11-17· MQ-135 Gas Sensor is an air quality sensor for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke, and CO2. MQ-135 sensor can either purchased as a module or just as a sensor alone. In this project, we are using an MQ-135 sensor module to measure CO2 concentration in PPM. The circuit diagram for the MQ-135 board is given below:
With remote toxic and Oxygen sensor mounting of up to 100 feet (30m) away from the transmitter, Sensepoint XCD provides a robust monitoring solution even in challenging environments where detection is difficult, including applications where the point of detection is in an area that is not easily accessible or where the detector would not be visible, like in high or low level concealed areas or ...
