Percent Oxygen Analyzer Introduction Introduction 1.1 Overview The Teledyne Instruments/ Analytical Instruments (TI/AI) Model 9060L is a microprocessor-based percent oxygen analyzer for real-time measurement of the percent of oxygen in inert gases, or in a wide variety of gas mixtures. It features simple operation, fast response, and a compact, rugged construction. Typical applications of the Model 9060L are monitoring kilns, boilers, and flue gas at temperature from ambient up to 1

Percent Oxygen Analyzer Operational Theory Operational Theory 2.1 Introduction The analyzer is composed of two subsystems: 1. Oxygen probe 2. Control unit with signal processing, display and controls The oxygen probe can be heated or unheated. It delivers the sample gas to a state-of-the-art zirconium sensor which translates the amount of oxygen present into a millivolt output. The control unit processes the sensor output and translates it into electrical concentration, range, and

Percent Oxygen Analyzer Operational Theory Probes of 1000 mm (40”) normally have sufficient length for any installation. Customers requiring probes longer than 1500 mm (59”) are supplied with a flow guide tube that uses the flue velocity to pull flue gas through a filter at the sensing tip and exhaust it near the flue wall. 2.2.1 Probe Configuration The probe can be configured in a variety of ways to suit the analytical environment. Figure 2-1 shows the most common configurable item

Operational Theory Model 9060L 2.2.2 The Zirconia Sensor Input to the analyzer is obtained from a solid electrolyte oxygen probe containing a zirconia element and thermocouple. The probe is designed to be inserted into a boiler or furnace exit gas flue or similar process. The 9060LEX sensor is designed to be installed outside of the flue or process. Sampling lines and filters are not required for in-situ probes but they are required for 9060LEX sensors. When a sampling line is required

Operational Theory Model 9060L THE PROBE/SENSOR MUST ALWAYS BE CONNECTED TO EARTH. Power to the heater is supplied directly from the main power source, and the temperature is initially controlled above 700°C (1300°F) after power up. 2.3 Applications Not at Atmospheric Pressure For high and low pressure applications where the pressure at the point of measurement is significantly above or below atmospheric pressure, compensation must be applied. The Model 9060L does not incorporat
