ATI Series D12 Toxic Gas Transmitter with H10 Smart Sensor
Revision N (7/15) 10
H10 Sensor Duct-Mount Option
The H10 sensor duct mount option allows H10 Smart Sensors to be installed in a duct or pipe, and
provides easy access to the sensor for service.
The assembly is comprised of a special H10 sensor holder (Figure 3) that slides into the hollow duct
mount adapter (Figure 4). The adapter has 1-1/2” MNPT threads on the insertion end, for securing it to
the duct or pipe, and a barb fitting for supplying calibration gas to the sensor. An interface cable is
provided to connect the sensor holder to the transmitter. Note that a mating flange for securing the
adapter is not provided.
As shown in Figure 5, screw the adapter to the duct or pipe so the barb fitting is accessible to connect
gas tubing. Once the adapter is in place, slide in the sensor holder, lock it in place, and connect the
interface cable. It is recommended that the sensor not be installed in the holder until you are ready to
start the transmitter. This is especially true during construction when excessive dust and dirt may be
blowing through the duct system, and otherwise foul the sensor.
