Duct Mount Kit

Gas monitoring in air ducts can be performed by means of this duct mount flange.
Install the sensor in a location that is convenient for maintenance, where it will be
exposed to a representative sample and is not subject to extremes of flow, turbu-
lence, temperature and particulate.
When installing, the direction of flow inside the duct must be as shown in Fig. 24.
Calibration of the device mounted in an air duct must be done with the HART inter-
face. Once calibration has been initiated, apply the calibration gasses via the gas
calibration port. Ensure that the duct is free of all gases to which the sensor will re-
spond and the duct flow rate is below 1 m/s. If hydrocarbon combustible gas is
present in the duct, the sensor must be removed from the duct during calibration.
The sensor can be removed from the duct mount bracket via four screws.
This duct mount kit is not included in the cFMus performance approval.
