Series 3500/3510 Trace Oxygen Transmitter

trace oxygen transmitter

The Series 3500 Trace Oxygen Transmitter is a true two-wire transmitter offering an economical way to make accurate and dependable measurements of trace oxygen in a variety of gases.

The Series 3510 Trace Oxygen Transmitter is the AC powered counterpart of the Series 3500.

 

Features Benefits

Wide Number of Ranges

Measure from <1ppm to 10,000 ppm Oxygen
Exceptional Speed of Response Responds Instantaneously to Changes in Oxygen
Rugged and Versatile Construction NEMA 4 Housing Withstands Harsh Environments
Economically Priced Save Thousands of Dollars vs Other Methods
Patented Electrochemical Sensor Offers Exceptional Accuracy and Stability
Sealed Sensor Eliminates Having to Handle Liquid Caustic

System Description
The Series 3500 Trace Oxygen Transmitter features an advanced electrochemical oxygen sensor that provides exceptional performance, accuracy, and stability. In addition, the enhanced mechanical design of the sensor ensures longer life, and virtually eliminates leakage of caustic electrolyte, a nagging problem associated with sensors that require periodic electrolyte maintenance. And, because the sensor is sealed, it is not position sensitive. In addition, Alpha Omega Instruments oxygen sensors are temperature compensated to provide optimum performance over a wide range of operating conditions.

The Series 3510 Trace Oxygen Transmitter is both dustproof and waterproof, and is rated for NEMA 4 (IP66) service. The instrument is powered from 115VAC, 60Hz, and provides a 4-20 mADC output that can be transmitted to a datalogger, recorder, PLC, DCS, etc. Internal shielding of the electronics offers excellent protection from EMI/RFI noise. Accessories for the Series 3510 Trace Oxygen Transmitter include a pressure regulator, in-line sample filter, and sample pump (shown in upper photo).

The Series 3510 Trace Oxygen Transmitter features an advanced electrochemical oxygen sensor that provides exceptional performance, accuracy, and stability. In addition, the enhanced mechanical design of the sensor ensures longer life, and virtually eliminates leakage of caustic electrolyte, a nagging (and expensive) problem associated with sensors that require periodic electrolyte maintenance. And, because the sensor is sealed, it is not position sensitive. In addition, the Series 3510 Trace Oxygen Transmitter does not require an adjustment in readings when the gas composition changes as do some other analyzers. The output from the sensor is temperature corrected to provide optimum performance over a wide range of operating conditions.
