LFG60 — multi-pollutant IAQ channel definitions
An all-in-one air-quality transmitter may combine multiple sensing principles, so each channel’s detection range, unit, accuracy and service life must be verified separately on LFG60’s exact configuration. The pictured display/top-suction variants are not identical installations. BMS integration must distinguish measured CO₂, temperature, RH and any inferred VOC/IAQ index. A combined module cannot automatically supply a regulatory-grade particulate or toxic-gas alarm.
LFG60 — seven IAQ channels with different physics and timing — engineering details
Hardware output variants, sensor channels and the original maker’s rated operating environment must be matched with the actual supplied part number.
| Technical parameter | Original manufacturer data | Application consequence |
|---|---|---|
| Channels | Up to temperature, RH, CO₂, PM2.5, PM10, VOC and formaldehyde | Up to seven measured parameters: different sensors, warmups and accuracy terms. |
| CO₂ | NDIR 0–5,000 ppm, ±(40 ppm + 3% of measured value), T90 ~2 min | Separate CO₂ ppm from a VOC metal-oxide reading. |
| PM | Laser optical PM2.5 0–500 µg/m³; PM10 0–600 µg/m³ | Dust accumulation and fog can bias optical mass; verify representative airflow. |
| VOC | MOX gas sensing 0–2 ppm; first startup about 1 hour and subsequent 3-minute warmup | VOC signal is not compound-specific worker exposure measurement. |
| Formaldehyde | Electrochemical HCHO 0–1 ppm; ±10% FS at 25 °C | HCHO is its own gas channel and requires selective calibration. |
| Temp/RH | 0–50 °C typically ±0.5 °C at 20 °C; RH 0–100% with typical ±3%RH | Each channel’s response and uncertainty should be logged separately. |
| Power and bus | 12–36 V DC / 24 VAC ±20%; isolated or non-isolated Modbus RS485 | Use isolated AC supply per maker note, proper terminal assignment and device addressing. |
| Physical design | Indoor or top-suction versions; IP30, optional LCD and status LEDs | IP30 is not a weather-protected rooftop sensor. |
Commissioning and maintenance
Treat each of the seven channels as independent input and alarm type. A single air-quality LED cannot replace traceable CO₂ ppm, selective formaldehyde ppm or particulate mass. The VOC sensor requires a much longer first power-on preheat than the quick PM response, so BAS commissioning should tag startup validity by channel. For a school or airport, verify Modbus addressing, installation airflow, PM dust servicing and HVAC control fail-safe. A combined device does not create a certified personal hazardous-gas alarm.
