Product Specification

OXY-Flex Oxygen Analyser Description
The OXY-Flex Oxygen Analyser is suitable for measuring in oxygen closed systems, such as ventilation pipes and boiler exhaust flues.

The OXY-Flex Oxygen Analyser is designed to measure the oxygen concentration in air or gas mixtures with temperatures of -100 to 400⁰C. The oxygen analyser 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 aluminium housing accommodates the electronics and provides the interface for the customer to connect to.

The OXY-Flex Oxygen Analyser 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.

OXY-Flex Zirconia O2 Sensors Oxygen Analyzer FEATURES
• High accuracy linear output
• Externally triggered automatic or manual calibration
• Can be calibrated in fresh air (20.7% O2 ) or to any other known O2 concentration
• Selectable output filtering allows adaptive, fast and dynamic or slow and stable output

OXY-Flex Zirconia O2 Sensors Oxygen Analyzer BENEFITS
• Cycling 3.3V DC logic output allows direct monitoring of the O2 sensor pump cycle for diagnostic purposes
• No reference gas required
