Introduction
1.1Overview
The Teledyne Analytical Instruments Model OT-2 System is designed to accurately monitor the oxygen content in a wide variety of gases at the ppm level. The Trace Oxygen Transmitter is equipped with two oxygen analysis ranges, 0–10 ppm and 0– 100 ppm (0-100 ppm and 0-1000 ppm optional). The OT-2 System is acceptable for operation in Class 1, Division 2, Groups B, C, and D hazardous environments, when used in conjunction with a non-insendive power source, such as the Elsag Baily Total Flow TM System.
The heart of the OT-2 System is Teledyne Analytical Instru- ments' Micro-Fuel Cell oxygen sensor. This cell is a sealed elec- trochemical device which translates the amount of oxygen present in a sample into an electrical current. Since it is sealed, there is no electrolyte to change or electrodes to clean and therefore, virtually maintenance free.
The transmitter operates from a 12VDC (nominal) power source and produces a 1-5VDC voltage output that is directly and linearly proportional to the oxygen concentration. The output voltage is used to interface with high input impedance (>10 Kilo ohms) devices such as recorders, alarms, computers or other voltage driven devices.
1.2Features
The following features describe the basic model. The exact configuration depends on the options selected at the time of purchase.
•Two analysis ranges: 0–10 ppm and 0-100 ppm (0-100 ppm and 0-1000 ppm optional) user selectable
•High sensitivity (0.5% FS)
•Digital O2 concentration display
