Aecl CO2 Transmitter (CO2 sensor, For High Humidity, Separated)

Product catalog summary

Overview: The AVC-320 Series Carbon Dioxide Transmitter is designed for high humidity environments, suitable for smart ventilation systems and environmental monitoring to control energy consumption and improve indoor air quality. It employs NDIR infrared waveguide technology for high accuracy and is commonly used in cellars, greenhouses, storage rooms, breweries, plant factories, and mushroom farms.

Specifications:

Sensing Element: Gold-plated infrared (NDIR) wave-guide technology with Automatic Baseline Correction (ABC) and passive gas diffusion.
Response Time: Less than 10 seconds at 30 cc/min flow rate; less than 3 minutes diffusion time.
Accuracy: At 25℃, 0~2000ppm (± 30ppm ±3% of reading), 2001~9999ppm (± 70ppm ±3% of reading).
Repeatability: ± 20ppm + (± reading * 1%).
Zero Drift: Less than ± 10ppm/year with ABC.
Measurement Range: 0 ~ 9999 ppm.
Signal Output: DC 4 ~ 20mA, RS485 (Modbus RTU).
Pressure Dependence: 1.6% reading per kPa.
Environmental Conditions: Temperature: -10 ~ +60℃; Humidity: 0 ~ 99%RH (without condensation).
Storage Temperature: -20 ~ +70℃.
Warm-up Time: ≤ 1 min. (at full specs ≤ 15 minutes).
Power Supply: 20 ~ 36V DC or 12 ~ 36V DC.
Power Consumption: 1.7W (Max.) or 1.4W (Max.).
Installation: Wall-mount.
Material: Main unit: Stainless steel; Fixed support: PE.
IP Rating: IP54.

Model Variants: AVC-320SAX-M and AVC-320S4X-M, differing in output and display options.

Notes:

ABC correction ensures accuracy with continuous detection over three weeks, but maintenance and calibration may be necessary for special applications.
Accuracy specifications are based on indoor temperature of 25℃ and normal air pressure of 101.3kPa.
