SITRANS AS100 and CU02 Acoustic Sensor Brochure

SITRANS AS 100
Proven continuous protection
for general industry
Stable, high frequency (75 to 175 kHz)
acoustic sensor for flow detection. The
0 to10 V DC analog output works
with SITRANS CU 02 or directly with
the customer’s PLC.

Easy, low-cost installation
Non-invasive mounting – screw-in,
bolt on, weld or bond in place with
optional mounting disc – ideal for
hazardous or hygienic environments
Low and high sensitivity ranges
Immune to plant vibrations
Compact stainless steel construction
for harsh environments
Extended temperature and
hazardous area options available
IP68 (waterproof) rated
SITRANS CU 02
Flexible control as a standalone system
or interfaced with the customer’s DCS
or PLC.

safe
Process protection devices act as an early warning system to avoid costly process interruptions and equipment breakdown. SITRANS AS 100 reacts instantly to changes in solids
flow to warn of blockages, product absence or equipment failure such as burst filter bags.
SITRANS CU 02 processes signals from the sensor, providing relay and analog outputs for
interface into a process. The two relays are fully programmable and independent of each
other. Low maintenance, easy to install and superior cost-effective protection,
SITRANS AS 100 and SITRANS CU 02 - a million in one.

Million in one
Process protection technology
with field experience
Siemens instruments come with
extensive field experience with a
million instruments in industrial
applications.
Designed to withstand the sustained rigors of heavy primary
industries, these products have
proven their reliability in a wide
range of harsh applications including the mining, mineral processing
and cement industries. They are
also used extensively in wet and
dry food processing and petrochemical industries.
With this experience, we understand the importance of
reliability, and we know what it
takes to make a trusted and
accurate instrument for demanding applications.
