Sunshield
The sunshield is a 316 stainless steel plate that protects the sensor from direct sunlight and from
excessive temperature rise.

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 repre-
sentative sample and is not subject to extremes of flow, turbulence, temperature and particulate.
When installing, the direction of flow inside the duct must be as shown in Fig. 25.
Calibration of the device mounted in an air duct must be done with the HART interface. Once calibra-
tion 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 respond 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.

Using the flow through adapter can extend the response time, depending on the gas flow rate
and system design.
