Introduction
1.1 Overview
The Teledyne Analytical Instruments (TAI) Model 3220 Oxygen
Monitor System is a multi-channel system that can be used for determining
the concentration of oxygen gas in an atmosphere at a number of remote
locations. The system provides alarm information when the oxygen
concentration exceeds user definable limits at any one or all of the remote
locations.
The oxygen gas content of the atmosphere is determined by a number
of remotely located sensors that may be strategically placed to monitor the
atmosphere surrounding their location.
The system is designed to provide indications of the state of each
sensor and to actuate individual external alarm indicators as well as alarms
common to all channels. The alarms are user-configurable.
1.2 Description
The 3220 system is comprised of a System Chassis, Control Unit,
Channel Modules, and Remote Probe Assemblies. Each System Chassis
contains one Control Unit and up to eight Channel Modules.
