aire^Ò Ventostat^Ò T8041 CO2 Duct Probe Transmitter – Simple Installation!!

The T8041 is a CO2 transmitter designed to be installed in HVAC return air ducts.  This product offers simplicity in design and installation.  Available with analog 0-10V output only.  Includes mounting hardware and installation instructions.

Specification

Measurement Range:     0-2000 PPM factory calibrated

Duct Air Velocity:     0 to 1500 ft/min

Temp Dependence:  0.2% of full scale per ºC

Stability:                    <2% of full scale over the life of the sensor （15 years typical）

Accuracy:                         ±40 PPM+3% of reading @22ºC （72ºF） when compared with a factory certified reference.

Non-linearity:                   <1% of full scale @22ºC （72ºF）

Pressure Dependence:   0.13% of reading per mm of mercury

Calibration:                      Sensors will be calibrated at zero and span at the factory. Calibration in the field will not be required. Sensors will be shipped with ABC Logic™ turned on.*

Response Time:               3 minutes typical for a 90% step change at low duct speeds.

Sampling Rate:               Every 2 seconds, 25% duty cycle

Warm up time:                 < 2minutes （Operational） 10 minutes to achieve maximum accuracy.

Operating Conditions:    Temperature:  0ºC to 50ºC （32ºF to 122ºF）

                                          Humidity:       0 to 95% Relative Humidity, non-condensing

Storage Conditions:        -20ºC to 70ºC （-40ºF to 158ºF）

Output:                             Analog 0 to 10 VDC （100 ohm output impedance）

Power Sup Reqmts:        18 to 30 VAC RMS, 50/60 Hz or 18 to 42 VDC, polarity protected.

Power Consumption:       Typical values （1.65 Watts Peak, 0.65 Watts Avg. @ 42 VDC）

*Note:  Automatic Background Calibration or ABC Logic™ is a patented self- calibration technique utilized in applications where concentrations will drop to outside ambient conditions  （Approximay 400 PPM） at least 3 times in a 14-day period, typically during unoccupied periods.  Full accuracy is achieved after two weeks of operation.
