2.4 Accessories and replacement parts

Interface adapter
The optionally available HART modem with RS232,
USB or Bluetooth interface enables the connection
of communication-capable instruments to the re-
spective interface of a PC. An adjustment software
like PACTware with COMM DTM HART and
Device DTM Generic HART is necessary for
parameter adjustment of these instruments.
The adjustment software PACTware and the
required DTMs is available free-of-charge under
www.wika.de.
External display and adjustment units DIH50,
DIH52 and DIH62
The adjustment units DIH50, DIH52 and DIH62 are
suitable for measured value indication and adjust-
ment of sensors with HART protocol. The respec-
tive adjustment unit is looped into the 4 ... 20 mA/
HART signal cable.
With sensors without HART protocol, the adjust-
ment units are suitable for measured value
indication.
You can find further information in the respective
operating instructions of the adjustment units
DIH50, DIH52 and DIH62.

3.1 General instructions

Suitability for the process conditions
Make sure that all parts of the instrument in
physical contact with the process are suitable for
the exisitng process conditions. These include in
particular the process pressure, process temper-
ature as well as the chemical properties of the
medium.
You can find the specifications in chapter "Tech-
nical data" and on the nameplate.
Pressure compensation
The suspension cable has a capillary for atmos-
pheric pressure compensation. Thus, make sure
the cable ends in a dry environment or suitable
terminal housing.
