sensor accuracy and field calibration the t6615 is a dual channel sensor. the two channels can be described as a co 2 channel that measures gas concentration and a reference channel that measures the sensor signal intensity. the t6615 performs periodic self-calibrations using the reference channel. the self calibrations are approximately every 24 hours but can also be initiated by sending a command (see communication protocol). self calibrations should not be performed during the warm-up period. during the self calibration the sensor ppm reading is frozen, it will not react to changing co 2 . the calibration time is adjustable but nominally two minutes. over time the minor electrical and mechanical changes can affect the sensor accuracy. with the exception of operation in harsh environments the rate of signal change is a decaying function, thus the longer the sensor operates the more stable it will become. the reference channel will correct for these changes over time. telaire recommends periodic gas calibration depending on the application accuracy requirements. while the reference channel corrects for changes over time, a feld calibration using nitrogen gas will immediately restore the highest level of accuracy. module t6615-f (flow through) the diffusion membrane is replaced with a non- permeable seal. the two fow ports can be used for fow through sampling. flow rate of 50 cc/min recommended. handling and installation the t6615 co 2 oem modules are infrared gas sensors on a printed circuit board and should be treated carefully. precautions should be taken to observe specifed limits and prevent damage from electrostatic discharge or rough handling. please refer to ansi/esd s20. 20-1999 for more information on preventing esd damage and ipc 610 rev d for more information on proper electronic assembly practices. available models part number sampling method measurement range t6615 diffusion 0-2,000 ppm t6615-5k diffusion 0-5,000 ppm t6615-10k diffusion 0-10,000 ppm t6615-50k diffusion 0-50,000 ppm t6615-f flow through 0-2,000 ppm t6615-5kf flow-through 0-5,000 ppm T6615-10KF flow-through 0-10,000 ppm t6615-50kf flow-through 0-50,000 ppm t6615-r12 diffusion, 12 second rate 0-2,000 ppm pin designations connector pinout function a tx (uart) b rx (uart) c v+ (5 vdc) 1 v+ (5 vdc) 2 gnd 3 gnd 4 av out (0 to 4 vdc) 5 no connect 6 no connect 7 no connect 8 no connect 9 no connect 10 tx (uart) 11 rx (uart) 12 gnd
