Here are some of the industries that use the Series 3500/3510 Trace Oxygen Transmitters:

• Semiconductor Manufacturing: Used in semiconductor manufacturing processes to monitor oxygen levels in process gases and to ensure the purity of the gases used in production.
• Food and Beverage: Used in the food and beverage industry to monitor oxygen levels in packaging and storage environments to extend the shelf life of products and to prevent spoilage.
• Pharmaceutical: Used in the pharmaceutical industry to monitor oxygen levels in production processes and to ensure the stability and efficacy of drug products.
• Petrochemical: Used in the petrochemical industry to monitor oxygen levels in refining and processing operations to optimize process efficiency and to prevent corrosion.
• Aerospace: Used in aerospace applications to measure oxygen levels in welding applications where excess oxygen promotes poor welds due to oxidation.
• Research: Can be used in research applications with glovebox or anaerobic chambers, such as studying the effect of oxygen levels on plant growth, and in testing the oxygen content of experimental gas mixtures.
• Industrial processes: Can be used in various industrial processes that require accurate measurement and control of oxygen levels, such as welding, metal processing and chemical processing.

• Long Life Trace Oxygen Sensor: Provides up to three times the functional life of most “fuel cell” type sensors. Reliability is dramatically increased while maintenance costs are reduced.
•  Sealed Sensor: Eliminates handling potassium hydroxide (caustic), a hazardous material or having to frequently “recharge” the electrolyte. 
• Affordable: Affords savings of up to 30% and more over other manufacturers trace oxygen transmitters.
•  Wide Measurement Range: Available measurement ranges are 0-500, 0-1000, and 0-5000 ppm oxygen.

• Measurement Ranges: (parts per million) 0-500, 0-1000, and 0-5000 ppm
• Accuracy¹: ±1% of full scale (± 5% of full scale on ranges ≤ 0-5ppm)
  • ¹Stated at constant temperature and pressure
• Linearity: + 1% of full scale.
• Response Time: 90% of full scale response in less than 10 seconds (typical). The response time for ranges of 0-50 PPM or less depend to a great extent on the design of the sample delivery system including the materials used.
• Sensor Type: Long-life Ambient Temperature Electrochemical Sensor 

• Polycarbonate, rated NEMA 4X (IP66) without optional equipment. 
• Dimensions: 5.5 in (139.9 mm) height. 8.8 in (223.5 mm) width. 3.4 in (86.4 mm) deep. Note: All dimensions are without optional equipment
• Gas Connections: 1/4” stainless steel compression fittings.

• Series 3500 Loop Powered Trace Oxygen Transmitter: Input power 14-32 VDC
• Analog Output: 4-20 mADC with a loop resistance of 600 ohms @ 24 VDC (consult factory for other resistance values).

• Sample Flow Rate: 1.0 to 2.0 standard cubic feet per hour (SCFH). 0.5 to 1.0 liters/ minute (LPM).
• Sample Gas Temperature: 40° to 104° F (5° to 40° C)
• Sample Gas Pressure Limits: 0.1 to 1.5 psig (0.007 to 0.1 kg/cm2).
• Entrained Solids: <3 mg/ft³: no in-line filter required >3 mg/ft³: in-line filter is required
• Hydrocarbon Mist: <0.7 mg/ft³: no in-line filter required >0.7 mg/ft³: in-line filter is required

We Care About Safety

If you are concerned over unsafe levels of oxygen explore a complete line of oxygen deficiency monitors and accessories. We supply many instruments to medical, aerospace, and municipalities.  Occupational Safety and Health Administration (OSHA) defines an oxygen deficient environment when oxygen levels fall below 19.5 percent.  Oxygen deficient environments require accurate and reliable instrumentation. Oxygen levels below 16% is dangerous to human life.
