DESIGN /
FUNCTION
The Ultrasonic
Level Transmitter Type 8175 combines an ultrasonic
sensor and a transducer with a large 8-digit
multi-language display in a splash-proof plastic
NEMA 4 enclosure.
The transmitter
is powered with 18-32 VDC (optionally 115/230
VAC) and features a three-wire 4-20 mA output
for direct controlling a continuous control
valve, a PLC, or for monitoring.
Two optional
3A relays can be configured as alarms or latched
for automatic fill or empty operations.
The transmitter
Type 8175 includes a range of fail-safe features.
Signal loss, power supply failure, level or
temperature alarm can be activated with an
adjustable time delay.
A range of
filter functions control the return echoes
and automatically eliminate all interference
due to elements of the vessel.
Easy and fast
commissioning is guaranteed with the “Teach-In”
and “Simulation” functions. Different tank
shapes (cylindrical, cubic, spherical) can
be easily programmed via fixed default shapes
or at complex tank shapes step by step.
The measured
value can be shown as a level, a distance
(in cm, m, inch or feet), or direct as a volume
(liter, m 3 , imp. gal, U.S. gal).
The simulation
functions allow the system to be tested under
dry-run conditions.
Burkert offers
the Ultrasonic Level Transmitter together
with process control valves as a complete,
easy to control system.
Easy commissioning,
installation and operation makes the Burkert
level control system number one in cost of
ownership.
