Part 3 – Sensor Installation
3.1
General
Select a location for the sensor on the side of the scrubber inlet or outlet duct.
Do not mount the sensor on the bottom of a horizontal duct section. If the duct is
horizontal, mount the sensor at about 45-60 degrees off of vertical.
The
preferred location for mounting the sensor is on a VERTICAL section of
duct
. Always select a location that allows for easy access to the sensor for
maintenance purposes. Placing the sensor in an inacessible location generally
leads to a lack of maintenance and ultimate failure of the system.

Sensor Duct Assembly
Figure 2shows the dimensions of the duct mount assembly used to insert the wet
hydrogen sulfide sensor into a scrubber duct. This assembly is designed to be
screwed into a 1½” NPT female adapter on the duct. The female adapter
attached to the duct must be supplied by the user.
