DUCT MOUNT SENSOR INSTALLATION
Duct mounted sensors are designed to be inserted into an air duct or pipe through a special
adapter fitting (part number 00-0814). This fitting has a 1” MNPT thread on the front for adapting to the
duct or pipe. The actual duct adapter is customer supplied.
Installation of this sensor requires that the 00-0814 adapter be screwed into the customer
supplied adapter as shown in Figure 5 below. Screw in the adapter so that the calibration gas inlet port is
oriented in a direction that gas tubing can easily be connected. Once the adapter is in place, the sensor
will slide into the adapter easily. However, it is recommended that the sensor not be installed in the fitting
until you are ready to start up the transmitter. This is especially true during construction when dust and
dirt may be blowing through the duct system. Fouling of the sensor may result.
