Controls HVAC

Simple installation (mounting hardware and instructions included)

• Ideally suited for larger HVAC return air ducts

• Offers standard 0-10 volt output Patented absorption infrared/gas sensing engine provides high accuracy in a compact low-cost package

• Patented ABC Logic™ self-calibration system eliminates the need for manual calibration in most applications

• Gas permeable, water resistant diffusion filter prevents particulate and water contamination of the sensor

• Lifetime calibration guarantee

• Two probe lengths avaliable

Measurement Range

0-2000 PPM factory calibrated

Duct Air Velocity

0 to 1500 ft/min (0 to 450 meter/min)

Temp Dependence

0.2% of full scale per ºC

Stability

<2% of full scale over the life of the sensor (10 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

Three minutes typical for a 90% step change at low duct speeds

Sampling Rate

Every two seconds, 25% duty cycle

Certifications

RoHS compliant

Warm-up Time

< two minutes (operational); 10 minutes to achieve maximum accuracy

Operating Conditions

• Temperature: 0ºC to 50ºC (32ºF to 122ºF)

• Humidity: 0 to 95% relative humidity, noncondensing

Storage Conditions

-20ºC to 70ºC (-40ºF to 158ºF)

Output

Analog 0 to 10 VDC (100 ohm output impedance)

Power Supply Requirements

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: The Telaire product line offers patented ABC Logic™ software for self-correction of drift to better than ±20 ppm per year. The system is virtually free of maintenance and typically has than 10 years.
