AAW85-07WA-CIT

Digital interface
The sensor has a UART protocol to communicate with the instrument with chip select option as described in Communication Protocol (SDCS).

Interchangeable
All intelligent sensors have the same dimensions and communication protocol. All sensors in the range will work with a supply voltage from 3.1 V to 3.3 V.

Digital traceability
Sensors contain the following data: serial number, manufacturing date, and gas type for quick and easy identification of the sensor.

OeM lock
Sensors have two levels of lock codes. The first one is an OeM specific code programmed in during manufacture and cannot be modified. This lock code is provided by the OeM. Instrument can check if the sensor has the unique code - if not the instrument can refuse the sensor. The second level of lock code is left blank and can be updated by OeM/Partners during sensor integration into the instrument as needed.

Pre-calibrated
Sensors will be calibrated during manufacturing and calibration data is written in the sensor. Sensor will output gas concentration when interrogated by instrument.

Predictive calibration
The recalibration alarm will be triggered when the countdown timer is reached.

end-of-life indication
The alarm will be flagged when the sensor has taken/lost a considerable amount of water (electrolyte concentration is above
or below limits).

Fault indication
Intelligent sensors can detect several internal faults like drift/fault in reference electrode, electrolyte concentration out of range, counter electrode fault; therefore notifying the user to take corrective actions.
