Product Specification

OXY-Flex-x Series DESCRIPTION
The OXY-FLEX-X Series Standard Temperature Oxygen Analyser is designed to determine the oxygen concentration in air or inert gas mixtures with temperatures of -100 to +250°C max.

The OXY-FLEX-X-H Series High Temperature Oxygen Analyser is designed to determine the oxygen concentration in air or inert gas mixtures with temperatures of -100 to +400°C max.

These products are particularly suitable for measuring oxygen in areas that are not easily accessible, or in closed systems, such as ventilation pipes, flues and containers.

The OXY-FLEX Series can be user configured to output measuring ranges of 0-25% O2 and 0-100% O2 . The entire measurement range is linear in both cases. Factory default is 0-25% O2. When configured for 0-100% O2 the user can also customise the analogue output ranges to suit their application.

The outputs can be configured to either 4-20mA and 0-10V DC or RS232 interface. Prior to shipping all OXY-FLEX’s are preconfigured with a measuring range of 0.1% to 25% Vol. O 2 with linear 4-20mA and 0-10V DC outputs.

All settings can be changed by the customer should their measurement or interface requirements change by simply altering the position of jumper links on the PCB.

OXY- Flex Oxygen Analyser FEATURES

* High accuracy linear output
* Configurable outputs: 4-20mA and 0-10 V DC or RS232 comms interface
* Selectable output measurement ranges: Standard ranges of 0-25% O2 and 0-100% O2 or fully adjustable via RS232 when configured in 0-100% O2 mode
* Externally triggered automatic or manual calibration
* Can be calibrated in normal air (20.7% O2 ) or in any other known O2 concentration
* Cycling 3.3 V DC logic output allows direct monitoring of the O2 sensor pump cycle for diagnostic purposes
* Selectable output filtering allows adaptive, fast and dynamic or slow and stable output
