We
supply
products
made
from
the
following
piezoelectric
ceramic
formulations:
-
PKI
100
Lead
Metaniobate
exhibits
properties
not
usually
present
in
other
types
of
piezoelectric
ceramics.
The
noteworthy
facts
are
its
low
mechanical
QM,
negligible
aging,
wide
range
of
operating
temperatures
and
small
values
for
lateral
and
planar
coupling
compared
to
longitudinal
coupling.
The
low
QM
enhances
the
use
of
PKI
100
material
in
the
construction
of
wide
bandwidth
sensors
for
high
frequency
pulse
echo
measurements
that
require
a
short
pulse
and
critical
resolution.
Its
negligible
aging
helps
simplify
circuit
design.
Wide
variations
in
temperature
have
limited
effect
on
its
dielectric
and
piezoelectric
properties
making
it
ideal
for
high
temperature
applications.
Its
high
longitudinal
coupling
compared
to
lateral
and
planar
coupling
allows
it
to
generate
a
better
response
under
hydrostatic
pressures
and
makes
it
useful
for
underwater
sonar
equipment.
