Mounting with PermaFiX
In explosive atmospheres of FM Class I, Division 1, the transducer mounting fixture PermaFiX has to be used, see Fig.
6.53.
When measuring in reflection arrangement, the transducers are installed on the same side of the pipe. If the transducer
distance is small, both transducers are mounted into one rail. If the transducer distance is large, it can be necessary to
mount 2 transducer mounting fixtures (one for each transducer).
When measuring in diagonal arrangement, the transducers are installed on opposite sides of the pipe.
The transducer mounting fixture PermaFiX can be installed on the pipe using screws or tension straps. Select the mount
-
ing instruction: On pipes with a diameter of max. 40 mm, it is recommended to use screws for the installation of the
PermaFiX and tension straps for larger pipes.
Installation of the rail with screws
The number and arrangement of PermaFiX rails depend on the required transducer arrangement and transducer distance.
See Fig. 6.54 for an overview of possible arrangements.
