Appendix

Specifications:

 

System Enclosure:

NEMA 4 Rated, bulkhead mounted

Power Requirements:

9-16 VDC and 16-275mA.

Ranges:

0–10ppm and 0–100ppm Oxygen

 

or 0-100 ppm and 0-1000 ppm O2.

Accuracy:

± 2% of full scale at constant temperature and

 

pressure (temperature and pressure of calibra-

 

tion), except ± 1ppm on 0 –10ppm range.

 

± 5% of full scale over operating temperature

 

range (once thermal equilibrium has been

 

reached), except ± 1ppm on 0 –10ppm range.

Response Time (90%): Sensor Response Time = 61 seconds @ 77°F

 

(25°C).

 

Overall system response time is flow rate

 

dependent.

Operating Temperature:

5-113°F (-15–45°C)

Stability:

± 1% in 24 hours (at constant temperature)

Reproducibility:

± 1% of full scale at constant temperature

Sensor Type:

Micro-Fuel Cell class B2C

 

Optional (application dependent): Micro-Fuel

 

Cell class A2C if CO2 concentration consis-

 

tently exceeds 1000 ppm.

Signal Output:

1-5 VDC
