Sapphire Single-Point Level System0 pages

Product Specifications
Thermo Scientific Sapphire singleand
dual-point level systems feature
an advanced acoustical design and
a continuous self-test to increase
reliability and uptime. Available in
gap or slot sensor configurations,
these field-proven ultrasonic devices
perform exceptionally well in
aerated, attenuative, viscous and
corrosive applications yet require
Thermo Scientific Sapphire minimal maintenance.
Single- and Dual-Point Level Systems
Reliable Level Measurement
Designed for both low and high level alarms
and spill prevention, Thermo Scientific
Sapphire single- and dual-point level systems
are available in gap and slot configurations
to provide reliable level measurement under
demanding conditions. The standard gap
sensor performs exceptionally well in most
applications, including aerated and
attenuating liquids that can be problematic
for other ultrasonic technologies. The more
sensitive slot sensor is recommended for
highly viscous applications or for dual-point
usage when the sensing points are
positioned more than 18 inches apart.
While both systems are highly reliable,
the dual-point system incorporates two
Sapphire single-point level systems into
one enclosure, including two electronics
packages. The dual-point system also offers
the industry’s best sensitivity with a wet
to dry ratio of over 10,000.
Rugged Design
Sapphire single- and dual-point level systems
are built for rugged industrial environments.
The variable system qualification time
guards against false alarms by accurately
determining the continuous presence of
liquid in the measurement gap rather than
allow a wave or other disturbance caused
by turbulence to trigger the alarm. The
rugged surface-mount technology increases
durability while the continuous self-test
circuitry increases uptime by automatically
confirming system integrity, including
the electronics and the sensor as well
as the crystal bond to the sensor body.
Easy Installation & Maintenance
The housing for both the Sapphire singleand
dual-point level systems provides easy
access to field wiring connections without
exposing the electronics to unnecessary
handling, harsh environments or physical
damage. During installation, the electronics
remain in the enclosure and are safely
protected as wire is pulled and field
terminations are made. For ongoing
maintenance, the manual loop test
enables field wiring and control integrity
verification without costly system removal
or tank filling.
