Dual-Channel Carbon dioxide Sensor
- product brand:HGGAOLI
- Numéro de stand：W5D49
- product specification:QTA-CSR12-1
- product category:Air Conditioning-Control equipment for intelligent building-Sensor
- product introduction:QTA-CSR12-1 Gas Sensor is integrated with a narrow-band optical filter at the receiver end, which allows only photons within the wavelength band corresponding to the CO? spectral absorption peak to pass through.?Filtered optical signals are?captured by a high-precision thermopile fabricated using MEMS-based processes and converted into electrical signals, which are then processed through specialized curve-fitting and filtering algorithms to obtain real-time CO? concentration within the gas chamber. Featuring a dual-channel design (detection and reference channels), it avoids light deviation caused by the aging of light source or gas chamber, enabling long-term calibration-free operation.
