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.
