8.3 Series 2000 /2510 Percent Oxygen Units
The Alpha Omega Series 2000 / 2510 units measure oxygen as a percent of the atmosphere volume with
the following specifications:
Measurement Ranges in percent: 0-2, 0-5, 0-10, 0-25, 0-50, 0-100 (specified at time of order)
Sample Gas pressure Limits: 0.1 to 1.0 PSIG
Sample Flow Rate: 1.0 to 2.0 SCFH
8.4 Series 3000 / 3510 Trace Oxygen Units
The Alpha Omega Series 3000 / 3510 units measure trace oxygen in ppm of atmosphere volume with the
following specifications:
Measurement Ranges in ppm: 0-10, 0-50, 0-100, 0-500, 0-1000, 0-5,000 0-10,000 (specified at
time of order)
Sample Gas pressure Limits: 0.1 to 1.0 PSIG
Sample Flow Rate: 1.0 to 2.0 SCFH
8.5 Analyzer and Transmitter Equipment Differences
The Series 2000 Percent Oxygen Analyzer and the Series 3000 Trace Oxygen Analyzer are complete
measurement devices. They have a keypad for data entry and programming, a sensor for Oxygen detection,
a display to view data, and audible and visible alarm programs to alert technicians to process problems.
The Series 2510 Percent Oxygen Transmitter and the Series 3510 Oxygen Transmitter will convert the
voltage generated by the sensor and transmit a 4-20 mA output to the controller (MP750 or UP750) Input 2.
When oxygen amounts exceed the setpoint value the controller will remove power to the heater elements
and activate one or more alarms. The controller will also provide the display value in ppm or percent of
oxygen present.
8.6 Optional Inert Gas Injection Rate Control
Injection rates of inert gas into the oven may be controlled. This is achieved using a time proportioned output
of either the main temperature controller that uses an Oxygen Transmitter or by an Oxygen Analyzer. The
output would energize and open the Gas Injection solenoid valve to maintain a ± 2% Oxygen level in the
chamber.
