Telaire T6793 — compact single-channel CO₂ with defined ABC limitations — model evidence and engineering selection
Current original manufacturer information differentiates optical design, gas span, data interfaces, revision-specific power and calibration assumptions.
| Characteristic | Source-backed detail | Selection consequence |
|---|---|---|
| Gas sensing | Gold-plated optical NDIR CO₂, diffusion and ABC Logic compensation | Single-channel background algorithm assumptions differ from T6615’s dual-reference design. |
| Exact model ranges | T6793 0–2,000ppm, T6793-5K 0–5,000ppm | Do not treat 5K digital range as shipped by every default base unit. |
| Accuracy band | 400–5,000ppm ±(45ppm +3% reading) at specified SATP conditions | A typical 1,000ppm expression yields ±75ppm, independent span gas also adds uncertainty. |
| Environment dependence | Temperature ~5ppm/°C or 0.5%reading/°C, whichever larger; pressure 0.13%reading/mmHg | Account for altitude/weather and enclosure temperature. |
| Digital refresh versus gas step | A new value every 5 seconds; T90 <3 minutes | The bus update is much faster than the gas chamber response. |
| Initial warmup | <2 minutes functional; about 10 minutes until maximum accuracy | BAS should not alarm based on unqualified post-power readings. |
| Digital/electrical | I²C to 100kHz, UART at 19,200 baud with Modbus framing; 4.5–5.5V DC | Host UART Modbus protocol does not imply native RS485 electrical transceiver. |
| Power envelope | About 25mA maximum average / 200mA peak, manufacturer order documentation | Dimension module power for optical pulse, not 20mA nominal average only. |
| Long life | Typical 15-year design and <2%FS lifetime stability | ABC needs suitable low-CO₂ exposure and field verification. |
Firmware, operating environment and calibration
Telaire’s T6793 is a compact HVAC sensor whose patented ABC Logic assumes a realistic low-CO₂ baseline. The maker warns sustained exposure below 400ppm can itself affect automatic correction, and a long-occupied space without outdoor background may not provide a reliable reference either. Distinguish 5-second data reporting from up-to-three-minute gas response, and record model suffix before scaling a 0–2kppm base unit as 5kppm. The USB evaluation kit and six-pin header are development accessories, not built-in industrial isolation or a finished safety alarm.
