Model GD-K71D4X Sample Draw Transmitter • 2
Description
This section describes the components of the GD-K71D4X. It consists of the enclosure and
a GD-K71D mounted inside.
A hydrophobic sample filter is also provided with the GD-K71D4X for installation near
the inlet fitting. The filter scrubs particulates out of the sample stream and keeps water
and many other liquids from entering the GD-K71D4X flow system.
Enclosure
The enclosure is a type NEMA 4X plastic enclosure designed for use in areas that are
subject to rain or hosing down. A mounting foot is installed in each corner. Two sample
fittings are mounted on the bottom right of the enclosure and two 3/4” conduit hubs are
mounted to the left of the sample fittings.
Sample Fittings
The inlet fitting is on the bottom right of the enclosure and the exhaust fitting is to the left
of the inlet fitting. The fittings accept 1/4”O.D. x 1/8” I.D. Teflon tubing.
Conduit Hubs
Two 3/4” conduit hubs are located to the left of the sample fittings. They are used for
routing wiring into the enclosure by using conduit or an appropriate cable bushing.
GD-K71D
The GD-K71D sample draw detector head is mounted to a plate inside the enclosure. The
GD-K71D sample fittings are factory connected to the sample fittings on the NEMA 4X
enclosure. See the GD-K71D operator’s manual for a complete description of the
GD-K71D.
