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.
