SST - Model OXY-Flex -Oxygen Analyser
The OXY-Flex Oxygen Analyzer is suitable for measuring in oxygen closed systems, such as ventilation pipes and boiler exhaust flues. The OXY-Flex Oxygen Analyzer is designed to measure the oxygen concentration in air or gas mixtures with temperatures of -100 to 400°C. The oxygen analyzer employs a well proven, small zirconium dioxide based element at its heart and due to its innovative design does not require a reference gas. The oxygen sensor element is mounted in the tip of the stainless steel probe and is protected by a sintered stainless steel cap.
The OXY-Flex Oxygen Analyzer uses a unique closed loop measurement system. While the sensor continuously measures the oxygen level, a heartbeat signal is also generated providing an immediate warning of any failures.
The OXY-Flex can be configured to output measuring ranges of 0-25% O2 or 0-100% O2. The entire measurement range is linear in both cases. The outputs can be configured to either 4-20mA and 0-10Vdc outputs or an RS232 serial communications interface.
Typical applications include; combustion control of industrial boilers, burning oil, gas, coal or biomass; incubators; composting probes and welding equipment.
- Configurable outputs: 4-20 mA and 0...10 V DC or RS232 comms interface
- Cycling 3.3 V DC logic output allows direct monitoring of the O2 sensor for diagnostic purposes
- Can be calibrated in normal air, 20.7 % O2, or in any other known O2 concentration
- Selectable output filtering allows fast and dynamic or slow and stable output
- Externally triggered automatic or manual calibration
- Sample temperature from -100 °C / -148 °F to +400 °C / 750 °F
- IP66 certified enclosure in either Aluminum or Stainless Steel
