Model 9060L Teledyne Analytical Instruments x DANGER COMBUSTIBLE GAS USAGE WARNING This is a general purpose instrument designed for use in a non-hazardous area. It is th e customer's responsibility to ensure safety especially when combustible gases are being analyzed since the potential of gas leaks always exist.
Percent Oxygen Analyzer Introduction Teledyne Analytical Instruments 11 Introduction 1.1 Overview The Teledyne Instruments/ Analyt ical Instruments (TI/AI) Model 9060L is a microprocessor-based per cent oxygen analyzer for real-time measurement of the percent of oxygen in inert gases, or in a wide variety of gas mixtures.
Introduction Model 9060L Teledyne Analytical Instruments 12 • Two concentration alarms w ith adjustable setpoints. • A failure alarm. • Three analog outputs: two for measurement (0–10VDC, and negative ground 4–20 mA DC) and one for range identification (0-10VDC).
Percent Oxygen Analyzer Introduction Teledyne Analytical Instruments 13 • Set Alarm 2 Sets the concentration at which alarm 2 activates upon dropping below the threshold (LO alarm). • Set HI Range Set the high analysis range for the instrument (up to 0-100%).
Introduction Model 9060L Teledyne Analytical Instruments 14 Figure 1-2 Rear Panel • Power Connection 110 VAC at 50/60 Hz. The connector housing includes the fuse holder and the power switch. (220VAC is optional via setting an internal switch). Fuse Holder: Replacing the fuse is described in Chapter 5, Maintenance.
Percent Oxygen Analyzer Operational Theory Teledyne Analytical Instruments 15 Operational Theory 2.1 Introduction The analyzer is composed of two subsystems: 1. Oxygen probe 2. Control unit with signal pro cessing, display and controls The oxygen probe can be heated or unheated.
Operational Theory Model 9060L Teledyne Analytical Instruments 16 All Teledyne oxygen probe or sensors are desi gned and manufactured to exacting standards of performance and reliabil ity and are the result of extensive re search and development.
Percent Oxygen Analyzer Operational Theory Teledyne Analytical Instruments 17 Probes of 1000 mm (40”) normally have sufficient length for any installation.
Operational Theory Model 9060L Teledyne Analytical Instruments 18 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 boile r or furnace exit gas flue or similar process.
Percent Oxygen Analyzer Operational Theory Teledyne Analytical Instruments 19 require a heater. When the outside a nd inside of the sensor are exposed to different oxygen partial pressures, an EMF (E).
Operational Theory Model 9060L Teledyne Analytical Instruments 20 THE PROBE/SENSOR MUST ALWAYS BE CONNECTED TO EART H. Power to the heater is supplied d irectly from the m ain power source, and the temperature is ini tially controlled a bove 700°C (1300°F) after power up.
Percent Oxygen Analyzer Operational Theory Teledyne Analytical Instruments 21 located on the Main PCB, which is mounted vertically, just behind the front panel of the control unit. 2.5.2 Signal Processing Figure 2-3 is a block diagram of the signal processing electronics described below.
Operational Theory Model 9060L Teledyne Analytical Instruments 22 The digital concentration signal al ong with input from the front panel buttons (KEYBOARD) is pro cessed by the micro-controller, and appropriate output signals are directed to the display and alarm relays.
Percent Oxygen Analyzer Installation Teledyne Analytical Instruments 23 Inst allation Installation of the analyzer includes: 1. Unpacking the system. 2. Mounting the control unit. 3. Installing the probe. 4. Making electrical connections. 5. Testing the installation.
Installation Model 9060L Teledyne Analytical Instruments 24 Note: Mount the probe as close to the combustion source as possible. This reduces the lag time inherent in the sampling process and results in better control.
Percent Oxygen Analyzer Installation Teledyne Analytical Instruments 25 probe or install a longer probe. This is normally caused by stratification of the flue gas. Figure 3-1: Oxygen Probe Mounting 3.4 Electrical Connections Figure 3-1 shows the Model 9060L rear panel.
Installation Model 9060L Teledyne Analytical Instruments 26 Figure 3-2: Model 9060L Rear panel 3.4.2 Analog Outputs There are three DC output signal connectors with screw terminals on the panel. There are two wires pe r output with the polarity noted.
Percent Oxygen Analyzer Installation Teledyne Analytical Instruments 27 The alarm relay circuits are designed for failsafe operation, meaning the relays are energized dur ing normal operation. If power fails the relays de-energize (alarm s activated).
Installation Model 9060L Teledyne Analytical Instruments 28 3.4.1 Oxygen Pr obe Connections The receptacle for the probe cable is located in the lower left-hand corner of the rear panel. The 6-pin polarized connector is keyed to fit only one way into the receptacle.

Percent Oxygen Analyzer Operation Teledyne Analytical Instruments 31 Operation 4.1 Introduction Once the analyzer has been mounted , the probe installed, and the electrical connections made, the an alyzer can be configured for your application. This involves se tting the system parameters: • Defining the user select able analysis ranges.
Operation Model 9060L Teledyne Analytical Instruments 32 4.2 Using the Function a nd Dat a Entry Buttons When no buttons on the analyzer ar e being pressed, the instrument is in the analyze mode. It is mon itoring the percent of oxygen in the sample gas that is flowing through the remote probe.
Percent Oxygen Analyzer Operation Teledyne Analytical Instruments 33 range full scale value, and it switches back to the LO range when the oxygen concentration reaches 85% of the LO range full scale value Note: The HI Range setpoint MUST be set at a higher concentration percentage than the LO Range setpoint.
Operation Model 9060L Teledyne Analytical Instruments 34 until the display reads the desired per cent concentration. If within 5 seconds no key is pressed, the instrum ent will return to the sample mode and display oxygen concentration.
Percent Oxygen Analyzer Operation Teledyne Analytical Instruments 35 2. Immediately (within 5 seconds) press either the Δ or ∇ button until Auto, Lo, or Hi displays on the LCD , as desired. After about three seconds, the an alyzer resumes monitoring in the selected range mode.
Operation Model 9060L Teledyne Analytical Instruments 36 for five minutes before timing- out. During this five minute interval, the LED will conti nue to track gas through the analyzer. 2. Flow span gas of a known oxygen concentration (between 1 and 16% oxygen) into the analyzer.
Percent Oxygen Analyzer Operation Teledyne Analytical Instruments 37 4.6.2 Air Calibration To perform air calibration, make sure you have air flowing through the same inlet you use for span calibration at a flow of 1- 5 liters per minute. Wait for readings to stabilize.
Operation Model 9060L Teledyne Analytical Instruments 38 Within the time the tem perature is being displayed, one can use the UP and DOWN arrow keys to adj ust the temperature, thus recalib rating the temperature readout. WARNING: TEMPERATURE READI NG IS CALIBRATED AT THE FACTORY.
