1 YEAR WARRANTY (12 months from date of shipment)
Nitric Oxide (NO)
Sensor: iNO M
Part Number: AF002-R00D

FEATURES AND BENEFITS

– Digital interface – The sensor has a UART protocol to communicate with the instrument with chip select option as described in the 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
Pre-calibrated – Sensors will be calibrated during manufacturing .and calibration data
is pre-loaded on the sensor. Sensor will output gas concentration when interrogated by instrument
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. If the lock code does not match, then the sensor can be rejected by the end-user’s device. The second level of lock code is left blank and can be updated by OEM/Partners during sensor integration into the instrument as needed
Predictive calibration*1 – The sensors can typically alert when its accuracy levels diminish and a recalibration may be required.
End-of-life indication*1 – The sensors can typically alert when its sensitivity levels have diminished to indicate the requirement of
a potential sensor replacement.
Fault indication*2 – The sensors can typically detect internal faults
like drift/fault in reference electrode, electrolyte concentration out of range, counter electrode fault; therefore notifying the user to take corrective actions
Compact form factor Three-year life RoHS compliant
POTENTIAL USE
Inhaled Nitric Oxide Therapy
Notes
- 1 It is the responsibility of the end-user and the device manufacturer (i.e. the manufacturer of the device in which the sensor is incorporated) to determine when calibration and replacement is needed.
- The algorithms used do not necessarily detect all possible degradation and failure modes
- 2 The sensor’s intelligent and fault indication features do not guarantee detection of all possible issues/faults.

1 Based on performance data collected during design validation testing of the iNO sensors over continuous high temp/high humidity and high temp/ low humidity operating conditions, (40°C @ 80 %RH, 40°C @ 20 %RH) with 50 ppm Nitric Oxide applied, it has been determined that the sensors show gas responses outside of the speciﬁed accuracy range after four weeks of exposure to these conditions. The initial drift can be corrected with a gas recalibration cycle at four weeks after which the sensors responses stabilize and the three month high gas recalibration interval is adequate to maintain accuracy
2 Based on performance data collected during design validation testing of both the iNO and iNO2 sensors over continuous high temp /high humidity and high temp/low humidity operating conditions (40°C @ 80 %RH, 40°C @ 20 %RH), it has been determined that both sensor types experience baseline Offset shift outside of the speciﬁed accuracy range after four weeks. This shift is not permanent and can be corrected with a baseline (air blank) recalibration cycle at a minimum interval of four weeks
Speciﬁcations are valid at 20°C, 50 %RH, and 1013 mBar using Honeywell recommended circuitry. Performance characteristics outline the performance of sensors supplied within the ﬁrst three months

Poisoning
Gas Sensors are typically designed to be used in a wide range of environments and harsh conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage, ﬁtting into instruments, and operation. When using sensors with printed circuit boards (PCBs), degreasing agents should be used before the sensor is ﬁtted.
Do not glue directly on or near the sensor as the solvent may cause crazing of the plastic.
Cross Sensitivity Table
Whilst iseries sensors are designed to be highly speciﬁc to the gas they are intended to measure, they will still respond to some degree to various other gases. The table below is not exclusive and other gases not included in the table may still cause a sensor to react.
IMPORTANT NOTE: The cross sensitivity data shown below does not form part of the product speciﬁcation and is provided for awareness only. Values quoted are based on tests conducted on a small number of sensors and any batch may show signiﬁcant variation. For the most accurate measurements, an instrument should be calibrated using the gas under investigation.

WARNING
MISUSE OF DOCUMENTATION

The information presented in this product sheet is for reference only. Do not use this document as a product installation guide.
Complete installation, operation, and maintenance information is provided in the instructions supplied with each product.

Failure to comply with these instructions could result in death or serious injury.

SAFETY NOTE

This sensor is designed to be used in safety-critical applications. To ensure that the sensor and/or instrument in which it is used, are operating properly, it is a requirement that the function of the device is confirmed by exposure to target gas (bump check) before each use of the sensor and/or instrument. Failure to carry out such tests may jeopardize the safety of people and property.
Under no circumstances should soldering be used to attach/install the sensors, as this can cause leakage of electrolytes. Connection should be made via a mounting socket and spring connector.
WARNING: SOLDERING TO PADS WILL RENDER YOUR WARRANTY VOID.
