319R Introduction 1.0

Introduction

The Teledyne Brown Engineering Analytical Instruments (TBE) Model 319R Oxygen Detector measures the percent of oxygen in a wide range of gases and gas mixtures. Modular and compact design provide outstanding performance and reliable on-line monitoring and make the 319R virtually maintenance-free.

A special range on the 319R enables you to calibrate in ambient air. The Micro-Fuel Cell produces an output that corresponds linearly to the oxygen concentration; the absence of oxygen produces zero current. This means you can use ambient air (20.9% oxygen) to calibrate, eliminating the need for special span gases.

The Model 319R contains a main PC board and power supply/inter- connection board housed in a rack mount enclosure. The oxygen probe can be separated from the unit by as much as 6 feet, depending on the level of electromagnetic noise in the operating environment.

Main Features

1.Two Ranges of Analysis. The Model 319R Oxygen Monitor features two analysis ranges: 0–200 PPM and 0–1999 PPM. A 0-25% range is accessible only during calibration to allow calibration in air.

2.Liquid Crystal Display Digital Readout. The digital front panel

LCD continuously displays and updates O2 monitoring levels and displays values when calibrating the instrument and setting the alarms. Note that the display will not read higher than 199.9 on the 200 PPM range and 1999 on the 2000 PPM range.

3.Percent of Range Alarms. Three (3) alarm relays are provided: one high and one low alarm, which are user adjustable, and one low alarm, factory set as a cell fail alarm at 2% of full scale.
