OXY-Flex Oxygen Analyzer

SST Sensing's OXY-Flex oxygen analyzer is suitable for measuring oxygen concentrations in air or gas mixtures in closed systems

Image of SST Sensing's OXY-Flex Oxygen AnalyserSST Sensing's 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°C 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 IP65 waterproof die-cast aluminum housing accommodates the electronics and provides the interface to which the customer can connect.

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% O2 to 25% O2 or 0 % O2 to 100% O2. The entire measurement range is linear in both cases. The outputs can be configured to either 4 mA to 20 mA and 0 VDC to 10 VDC outputs or an RS-232 serial communications interface.

  • Cycling 3.3 VDC logic output allows direct monitoring of the O2 sensor pump cycle for diagnostic purposes
  • No reference gas required
  • 4 mA to 20 mA or 0 VDC to 10 VDC analog or RS-232 digital output options
  • < 15 s response time
  • Gas flow rate 0 m/s to 10 m/s
  • Operating temperature of -10°C to +85°C
  • 24 VDC supply voltage
  • Permissible gas temperatures -100°C to +400°C
  • Combustion control of industrial boilers, burning oil, gas, coal, or biomass
  • Incubators
  • Composting probes
  • Welding equipment
