GENERAL DESCRIPTION
The Gladiator Smart Admittance Switch
is a third generation, state-of-the-art
level probe, designed to operate in
tough industrial environments. The
probe of the Admittance Switch forms
one plate of a capacitance circuit, with
the vessel wall making the second plate.
The dielectric constant of the product
between the probe and the vessel wall
will cause a capacitive change as the
level approaches the probe, and the
output will switch in response. A special
circuit is used to ignore product build-up
between the sensing probe (active ele-
ment) and guard, and also between the
guard and vessel wall. The output has
adjustable hysteresis and delays for ‘on’
or ‘off’ switching.
A test function is available to remotely
conrm the probe integrity by switching
the relay contacts.
The Gladiator Smart Switch Series
includes communications capability for
remote adjustment, control and monitor-
ing.
Principle of Operation
The dielectric constant of the material
in the vessel will be different to that of
air. When the material comes near or in
contact with the probe an admittance
change will occur. The resonant fre-
quency of the internal oscillator will then
change. The relay will switch when the
frequency reaches the user selected
Switch Point value.
