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.
In general, OPTISWITCH 5300 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.
The tuning fork has lateral markings (notches) that indicate the
switching point with vertical mounting. The switching point applies
to water in conjunction with the basic setting of the density switch
≥ 0.7 g/cm³ (0.025 lbs/in³). When mounting OPTISWITCH 5300 C ,
make sure that this marking is at the height of the requested switch-
ing point. Keep in mind that the switching point of the instrument will
shift if the medium has a density other than water - water is 1 g/cm³
(0.036 lbs/in³). For products ≤ 0.7 g/cm³ (0.025 lbs/in³) and ≥ 0.47 g/
cm³ (0.017 lbs/in³) the density switch must be set to ≥ 0.47 g/cm³.
Keep in mind that foams with a density ≥ 0.45 g/cm³ (0.016 lbs/in³)
are detected by the sensor. This can lead to erroneous switchings,
particulary when the sensor is used for dry run protection.
