8.  ACCESSORIES

8.1  Scale and tag marking
BA444DF-F  indicators  are  fitted  with  a  blank
escutcheon  around  the  liquid  crystal  display.    If
specified  when  the  instrument  is  ordered,  this  can
be supplied printed with units of measurement and
tag  information,  plus  a  scale  for  the  horizontal
bargraph.  Alternatively, information may be added
on-site  via  an  embossed  strip,  dry  transfer  or  a
permanent marker.

If  separate  units  of  measurement  or  identification
are required for each  process  variable  this  can  be
provided on the tag plate see 8.2

To  gain  access  to  the  display  escutcheon  remove
the  terminal  cover  by  unscrewing  the  two  'A'
screws which will reveal two concealed 'D' screws.
Unscrew all four 'D' screws and carefully lift off the
front  of  the  instrument.      The  location  of  these
screws is shown in Fig 2.

After  adding  the  required  legends,  or  fitting  a  new
pre-printed  self-adhesive  escutcheon,  ensure  that
the 

gasket 

is 

correctly 

positioned 

before

reassembling the instrument enclosure.

8.2  Tag plate
The  BA444DF-F  can  be  supplied  with  a  blank  or
custom laser marked  stainless  steel  plate  secured
by  two  screws  to  the  front  of  the  instrument
enclosure. This plate can accommodate:

        1 row of 9 alphanumeric characters 10mm high

   or  1 row of 11 alphanumeric characters 7mm high

   or  2 rows of 18 alphanumeric characters 5mm
         high.

   or  8 cells each containing units of measurement or
         identification for one of the 8 inputs.

8.3  Pipe mounting kits
Two  pipe  mounting  kits  are  available  for  securing
the BA444DF-F to a horizontal or vertical pipe.

BA392D Stainless  steel  bracket  secured  by  two

worm  drive  hose  clips  for  60  to  80mm
outside diameter pipes.

BA393

Heavy-duty  stainless  steel  bracket
secured by a single 'V' bolt.  Will clamp
to  any  pipe  with  an  outside  diameter
between 40 and 80mm.
