4.1 General instructions
Make sure that all parts of the instrument coming in direct contact
with the process, especially the sensor element, process seal and
process fitting, are suitable for the existing process conditions, such
as process pressure, process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "
Technical data
" and on the
nameplate.
The instrument is suitable for standard and extended ambient condi
-
tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1.
In general, OPTISWITCH 4000 C can be installed in any position. The
instrument only has to be mounted in such a way that the tuning fork
is at the height of the desired switching point.
Keep in mind that the swichting point can vary dependent on the
installation position.
The switching point refers to the medium water (1 g/cm³/0.036 lbs/
in³). Please keep in mind that the switching point of the instrument
shifts when the medium has a density differing from water.
