Operation
3.1 Installation
Installation consists of mounting the detector in its associated sampling geometry and making the
required electrical connections. Refer to the applicable sampling geometry instruction manual for
detector installation instructions.
CAUTION
Remove all power prior to installing the Detector.
Detector Mounting
The detector is designed to be installed within a sampling geometry. The detector is normally part of the
process pressure boundary, and is normally installed using to mounting flanges and 2 quad-lobed seal o-
rings. The basic mounting procedure is provided below. Refer to the specific sampling geometry
installation procedure for further information.
The following materials are normally needed to remove or install the Model 943-27 detector:
O-Ring Lubricant, Dow Corning #55, or equivalent
1ea, 3/16 Hex head bit or T-handle tool
1ea, P/N 943-27-47, Detector Mounting Flange
1ea, P/N 46-103, Quad lobed seal (Detector mounting flange to Adapter flange)
6ea, P/N 5-610, 10-32 x 0.62 Socket head cap screws (varies with application)
6ea, P/N 5-795, #10 split washes, Stn Stl (varies with application)
1ea, P/N 943-27-48, Adaptor Flange
1ea, P/N 46-104, Quad lobed seal (Adapter flange to sampler body)
6ea, P/N 5-1080, 10-32 x 0.88 Socket head cap screws (varies with application)
6ea, P/N 5-795, #10 split washes, Stn Stl (varies with application)
6ea, P/N 5-795, #10 flat washers, Stn Stl (varies with application)
CAUTION
Due to the potential for high activity radioactive
gasses in or around the vicinity of the detector,
protective Clothing should be worn while installing
or removing the detector
Detector Installation
Detector installation includes installing the adaptor flange and quad-lobed seal o-ring, installing the
detector mounting flange, detector flange quad-lobed seal o-ring, inserting the detector into the detector
mounting tube and securing the detector mounting flange. The high voltage power supply for the detector,
if operational, must be turned off by turning the controlling Digital Ratemeter or 960 System power OFF.
