Section II Operating Instructions Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual 5.4. SETUP RNGE: ANALOG OUTPUT REPORTING RANGE CONFIGURATION 5.4.1. PHYSICAL RANGE VERSUS ANALOG OUTPUT REPORTING RANGES Functionally, the T802 analyzers have one hardware PHYSICAL RANGE that is capable of determining O2 concentrations from 0.00 % to 100.00 %. This architecture improves reliability and accuracy by avoiding the need for extra, switchable, gain-amplification circuitry.
Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual 5.4.2. ANALOG OUTPUT RANGES FOR O2 CONCENTRATION The analyzer has several active analog output signals accessible through a connector on the rear panel (see Figure 3-4).
Section II Operating Instructions Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual 5.4.3. REPORTING RANGE MODES The T802 provides three analog output range modes to choose from. Single range (SNGL) mode sets a single maximum range for the analog output. If single range is selected both outputs are slaved together and will represent the same measurement span (e.g. 0-20 %), however their electronic signal levels may be configured for different ranges (e.g. 0-10 VDC vs. 0.1 VDC).
Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual 5.4.3.1. RNGE MODE SNGL: CONFIGURING THE T802 ANALYZER FOR SINGLE RANGE MODE Single Range Mode (SNGL) is the default reporting range mode for the analyzer. When the single range mode is selected (SNGL), all analog O2 concentration outputs (A1 and A2) are slaved together and set to the same reporting range limits (e.g. 0- 22.00 %). The span limit of this reporting range can be set to any value within the physical range of the analyzer.
Section II Operating Instructions Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual 5.4.3.2. RNGE MODE DUAL: CONFIGURING THE T802 ANALYZER FOR DUAL RANGE MODE Selecting the DUAL range mode allows the A1 and A2 outputs to be configured with different reporting ranges. The analyzer software calls these two ranges RNG1 (low) and RNG2 (high). The O2L RANGE 1 setting corresponds with the analog output labeled A1 on the rear panel of the instrument.
Teledyne API Note T802 Paramagnetic O2 Analyzer Operation Manual If the optional CO2 sensor is installed, the concentration field of the T802’s display will report a value labeled, ”CO2 RANGE:”. Only one test function is available (CO2 RNG) which reflects the range setting for C2L and only this value is reported via the analyzer’s Analog Outputs (Output A3). To set the upper range limit for each independent reporting range, press: .
Section II Operating Instructions Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual 5.4.3.3. RNGE MODE AUTO: CONFIGURING THE T802 ANALYZER FOR AUTO RANGE MODE In AUTO range mode, the analyzer automatically switches the reporting range between two user-defined ranges (low and high). The unit will switch from low range to high range when the O2 concentration exceeds 98% of the low range span.
Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual (The ACAL submenu in the Primary Setup Menu is a special configuration; consult factory). 5.4.4. SETUP RNGE DIL: USING THE OPTIONAL DILUTION RATIO FEATURE This feature is a optional software utility that allows the user to compensate for any dilution of the sample gas that may occur before it enters the sample inlet.
Section II Operating Instructions Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual 3. Ensure that the upper span limit entered for the reporting range is the maximum expected concentration of the non-diluted gas. 4. Set the dilution factor as a gain (e.g., a value of 20 means 20 parts diluent and 1 part of sample gas): 5. Calibrate the analyzer.

Maintenance Schedule & Procedures Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual 12. PRINCIPLES OF OPERATION The T802 parametric oxygen analyzer is a microprocessor-controlled analyzer that determines the percent concentration of molecular oxygen (O2) in a sample gas drawn through the instrument.
Principles of Operation Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual Figure 12-1: Paramagnetic O2 Sensor Design When sample gas containing oxygen flows into the magneto-mechanical sensor, the O2 molecules are drawn toward the strong point of the magnetic field. This causes the N2 filled spheres to deflect even more so that the suspended dumbbell body pivots on the platinum wire. The more O2 present the further the dumbbell body is deflected from its neutral position.
Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual Principles of Operation This current is passed to a feedback loop, which generates a second current to a wire winding (in effect, a small DC electric motor) mounted on the suspended mirror. The more O2 present, the more the dumbbell and its attached mirror moves and the more current is needed to move the dumbbell back to it’s zero position.

Principles of Operation Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual Figure 12-5: T802 – Internal Pneumatic Flow with CO2 Sensor Option 12.4. FLOW RATE CONTROL To maintain a constant flow rate of the sample gas through the instrument, the T802 uses a special flow control assembly located in the exhaust gas line just before the optional internal pump or connected to the rear panel if using an external pump. These assemblies consist of: A critical flow orifice.
Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual Principles of Operation As the pressure on the downstream side of the orifice (the pump side) continues to drop, the speed that the gas flows though the orifice continues to rise. Once the ratio of upstream pressure to downstream pressure is greater than 2:1, the velocity of the gas through the orifice reaches the speed of sound.
Principles of Operation Teledyne API T802 Paramagnetic O2 Analyzer Operation Manual compensate the concentration measurement for changes in ambient air pressure. This sensor is mounted to a printed circuit board with the sample flow sensor on the sample chamber; see the following section and Figure 3-5. 12.4.3.2.
