Installation
3.4 Installing the Sensor in the Sample Stream
Locate the sensor as close a possible to the instrument. The convertible style sensor may
be immersion mounted by threading it onto the end of a pipe of an appropriate length. It
may also be mounted in any standard 2-in. NPT pipe tee, weldolet, or pipe saddle using
the special union mount adapter. In addition, the sensor may be installed in a ball valve in
a pressurized or non-pressurized process pipe/vessel.
The sanitary-style sensor may be clamp-mounted for clean-in-place applications using a
sanitary clamp-type tee or ferrule and a heavy-duty clamp.
Examples of common sensor installations are shown in Figure 8 and dimension drawings
are shown in Figure 1 and Figure 2 on page 8 . Refer to the instructions supplied with the
mounting hardware for installation specifics.
