A.3.7 Probes
Probe versions
Coaxial, Rigid Twin and Rigid Single Lead, Segmented Rigid
Single Lead, Flexible Twin and Flexible Single Lead. Probes
can be ordered in different materials and options for
extreme temperatures and pressure.
For guidelines on which probe to select depending on
application, see the Guided Wave Radar Application
Guidelines
Technical Note .
Total probe length
This is defined from the upper reference point to the end of
the probe (weight included, if applicable).
Select the probe length according to the required
measuring range (the probe must be hung and fully
extended through the entire distance where level readings
are desired).
Cut-to-fit probes
Most of the probes can be cut in field. However, there are
some restrictions for the standard and HP/C coaxial probes:
these can be cut up to 2 ft. (0.6 m). Probes shorter than 4.1
ft. (1.25 m) can be cut to the minimum length of 1.3 ft. (0.4
m). The HTHP coaxial probe and the PTFE covered probes
cannot be cut in the field.
Minimum and maximum probe length
Probe angle
0 to 90 degrees from vertical axis
Note
Models with QT option code should not be installed in
angled probe installations.
