1 Introduction

Model OT-2 System

 

 

 

 

 

 

Accurate (±2% of full scale at constant temperature on 100 ppm, or 1000 ppm scale; ±1 ppm on 0–10 ppm scale at constant temperature)

Insensitive to flow variations

Fast response and recovery

Long life, maintenance-free Micro-Fuel Cell oxygen sensor

Unaffected by reducing agents (HC's, CO, SO2, etc.)

Easy to calibrate, no zero gas required

12VDC Battery Powered w/ 1-5 VDC Output

Rugged NEMA 4, bulkhead mounted enclosure

Stainless Steel sample system (nylon cell holder)

H2S scrubber

Pressure regulation with gage

Sample filter

Flowmeter

Heated cell holder assembly

1.3Typical Applications

Although the OT-2 System is designed in conjunction with the Elsag Baily Total Flow TM System for natural gas production, it also is capable of monitoring oxygen at the ppm level in a variety of gases. A few typical applications include:

Gas gathering and transportation

Monitoring inert gas blanketing

Air separation and liquefaction

Chemical feedstock analysis

Petrochemical process control

Heat treating and bright annealing processes

Quality assurance

Gas certification

Welding applications
