DESCRIPTION
The O2I-FLEX Interface provides all necessaryelectronics to power and control SST Sensing’s range ofdynamic Oxygen Sensors.
The O2I-FLEX Interface can be user configured to outputmeasuring ranges
of 0-25% O 2 and 0-100% O 2 . The entire measurement range is linear
in both cases. Factory default is 0-25% O2. When configured for 0-100% O
2 the user can also customise the analogue output ranges to suit their
application.
The interface outputs the measured values simultaneously via 4 output
channels, 4-20mA, 0-10V DC and RS232 (Rx and Tx), all outputs are
referenced to the system GND.
A digital 3.3V DC logic output cycles at the same frequency as the
electrochemical pumping action of the oxygen sensing cell during normal
operation, thus providing a real time sensor health check, if the output
ceases to cycle the sensor has entered a start-up or error state. This
provides fault proof operation. The digital output is also used during
the calibration process to indicate the interface status. A green
on-board LED mirrors the CYCLE output and can be used to visually
determine the sensor status or during the calibration process. A red LED
indicates the unit has power applied.
SST’s range of oxygen sensors do not directly measure the oxygen
concentration but instead measure the partial pressure of oxygen within
the measurement gas. In order to output an oxygen concentration (%) the
O2I-FLEX must be calibrated, or more specifically, re-referenced in a
known gas concentration, typically normal air. Calibration, or
re-referencing, is achieved by connecting the calibration input to GND
or by pressing the on-board calibration switch and monitoring the status
of the digital cycle output or by visually monitoring the on-board
green LED. During the calibration process the output will either
automatically calibrate to a fixed reference or can be manually
calibrated to any output by way of a PCB mounted potentiometer. The
fixed reference is factory set to 20.7% O 2 for calibration in normal
air though this value may be altered via the RS232 interface for
calibration with a reference gas of any known oxygen concentration.
Calibration is stored on power loss.The auto or manual calibrate
function is user configurable. Regular calibration removes the effects
of application and atmospheric pressure changes and also
eliminates any sensor drift that may occur during the first few hundred hours of operation.
