57-642 ECLIPSE Model 705 Guided Wave Radar Transmitter for Hygienic Industries
similar to those used to maintain the position of spray balls
should be incorporated into the design and welded to the
flange assembly of the guided wave radar unit.
NOTE: If an alignment hook is not feasible, “match-mark” the process
connection on the probe to the process connection on the vessel.
4.2 Probe Bends
Often it is necessary to bend the probe to accommodate the
constraints of the application. The ECLIPSE Model 705
utilizes a probe that can be bent to maximize yields while
avoiding disturbances. Use the following guidelines for
bending a probe to improve the overall performance and
reliability of the installation.
NOTE: The orientation is critical to the performance of the installation.
4.2.1 Shallow Bends
The bend design should be as shallow as possible. A shallow
bend is best characterized as one that is very large on the
side of the probe where the bending mechanism is located.
Positioning the bend as high as possible, in relation to the
top of the probe, will assist in keeping this angle shallow.
Installation design should avoid placing bends in probes at
critical measurement points as it relates to the process. This
will ensure that the device provides the highest level of per-
formance possible.
4.2.2 Field Bends
The MAGNETROL ECLIPSE Guided Wave Radar probe
can be modified in the field. This includes modifications in
length as well as probe bending. Many times this will
reduce or eliminate extra shipping cost due to irregular
packaging as well as reduce delivery time by eliminating
drawing approval.
When bending the probe in the field, do not apply stress
(e.g., clamping) to the flange assembly. This can damage
components internal to the portion of the device responsi-
ble for transferring signal and maintaining hygienic seal
from the process.
NOTE: Do not apply any force to the process adaptor or transmitter as
this may cause damage.
Use a ½" conduit bending device on probes that are ½" bar
stock or less for simple bends. Probes constructed from bar
stock grater than ½" will require considerable force.
Therefore, a hand crank style bending may be ideal.
