Dependability, strength, durability, ruggedness
are the keywords when it comes to the use
of level instruments for continuous monitoring
in difficult environment conditions. The
ILC... series stands up to the requirements
of a tough continuous level detector and
offers the following benefits:
Level measurement is displayed on
a built-in Digital Panel Meter having
0.5 inch high digits for better visibility.
Standard output signal of 0-5 V
DC and 0/4-20 mA DC proportional to
0-100% level change available for remote
indicators and recorders.
'In Situ' range selection and calibration
possible from evaluation unit. Probe
head accessibility not required.
Measuring system has no moving parts
so does not suffer any mechanical wear
and tear and hence is maintenance free.
Economical to install, since ordinary
3-core cable is used for interconnection.
Flame-proof probe suitable for hazardous
areas as per IS-2148 for group IIA and
IIB is available.
As far as the service material is concerned,
the Continuous Level Indicator can be used
with conductive or non-conductive liquids,
powdered or grained materials of homogeneous
composition having stable dielectric constant.
Our clients in the Oil, Food, Water treatment,
Diesel, Chemicals etc. industries have used
the capacitance continuous level indicator
to their satisfaction.
In the ILC...series the measuring electrode
and container wall (or grounding probe)
form a capacitor with the material serving
as the dielectric. A change in material
level in the container causes a change in
capacitance. The electronic insert converts
this change to a proportional DC which is
transmitted via the interconnecting cable
to the evaluation unit wherein the signal
after processing is displayed digitally.
A Reference probe is required, when the
tank is non-metallic and a grounding tube
is required, when the liquid is turbulent
or tank shape is curved.
