2.2 Machining of Probe Inlet
The DT450G is designed for mounting on a socket or flange attached to an inlet on a duct
or other alternative facility. Equip the inlet with a socket or flange that complies with the
specifications of the DT450G. At this point, make sure the DT450G’s casing and the duct are in
electrical continuity.

When Mounting to Socket
Use the socket that comes with the DT450G for installation. Weld this socket paying attention to
the following precautions.
• The standard insertion length of the sensor probe is 460 mm.
• For welding the socket, cut out a 38.0 mm diameter hole on the duct or pipe. (The socket’s
outer diameter is 37.7 mm.)
• Weld all around the socket (316L SS). Make sure there are no spots not welded. Be careful
not to deform the socket while welding. Be careful about the orientation of the socket. When
installing the dust monitor on a vertical plane, place the cutout for air tubing at the bottom.
