Model OT-2 System Appendix

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
