Percent Oxygen Monitoring System Teledyne Analytical Instruments (TAI) Model 3220 Oxygen Deficiency Detection System provides a streamlined and rugged solution to monitoring breathing oxygen levels in any indoor location where compressed gases may be present. The 3220 consists of channel modules, each capable of interface with a detector monitoring ambient oxygen levels at a remote location. Detector modules utilize TAI’s Class B-3 Micro-Fuel Cell with rugged and easy-to-maintain design, simplifying maintenance. Channel modules can be mounted in a control module, which can be provided in a 3 or 8 channel configuration available in rack, panel and wall-mount designs. Individual channels can be installed into unused slots or removed as required. Each channel module includes a 0-10 VDC or 4-20mA (negative ground) analog output and two fully-configurable alarms with Form-C contacts. Easy-to-view LEDs give local indication as to an alarm condition.
