Functional characteristics:
CO2 sensors and products are mainly suitable for real-time monitoring of the concentration of carbon dioxide in the air. Widely used in indoor air quality testing, ventilation control system, building, hospital, School of carbon dioxide gas monitoring, air conditioning, air purifier, mushroom house, carbon dioxide gas fireplace in indoor air control, and transported to three output modes for PLC/ DCS / DDC control system,
Main technical indicators:
1. Detection principle: non dispersive infrared carbon dioxide sensor (NDIR).
Two. Measurement range: 0 ~ 3000ppm or 0 ~ 5000ppm maximum 0 ~ 100% (pre order selection).
Three. Life span: more than 10 years.
Four. Precision: + 2% ppm (0~3000ppm) @10 ~ 50 C.
Five, response time: 0 ~ 80% < 30sec.
Six. Data update: 2 seconds.
Seven, preheating time: @25 C < 90sec.
Eight. Working environment: 0 ~ 50 C, 0 ~ 95%RH Non Condensing.
Nine. The storage environment: -20 C ~ 70 C.
Ten, output: analog output: 4-20Ma, 0-10V, 0-5V, digital output: RS485.
Eleven. Input voltage: DC12V + 100mV Input (recommend 12V).
Twelve. Consumption of current: Peak 150mA, Low 25mA (@12VDC).
Note: (1) the output data in the preheating time is 0ppm, and the sensor has a self-examination process.
The range of the analog signal corresponding to the sensor is a linear signal.
