A text area at the top is (big bar) 2-Spaltig, so the text extends upwards!
Then adjust the transparent beams according to and while holding the
8 mm distance from text.
I think this means that, if you need to add more lines of text, extend the big
bar upwards, while maintaining the proper distance from the text.
The lower pane (smal bar, Dokuklasse) must be only single-column!

damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will be
used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property
damage.

SITRANS AS100 Sensor
SITRANS AS100 is an acoustic sensor for flow detection. It monitors high frequency acoustic
emissions (sound waves) generated by:
●the friction and impact of solids flow in pipes, chutes, and conveyors
●cavitation occurring in pumps, pipes, and valves
●turbulence of gases or liquids leaking through valves and flanges
●friction and jarring of mechanical parts
Acoustic emissions travel readily through solid materials such as metal, but are strongly
attenuated when traveling through air. As such, the Sensor is immune to airborne interferences
and provides a non-invasive method of monitoring process activities.
The sensor can be configured electrically during wiring to operate in either low or high sensitivity
range mode. The high sensitivity range applies where highest signal levels vary up to 40 dB. The
low sensitivity range applies where highest signal levels vary between 28 and 68 dB.
SITRANS AS100 Sensor provides an analog output for use with the Sitrans Control Unit. The
Sensor may be operated independently from the Control Unit by providing an external supply.
The output is fed into a control panel, chart recorder, data logger, or programmable logic
controller with a suitable input.
SITRANS AS100 Sensor is primarily used for solids flow detection. However, this device can be
used in pump cavitation and fluid leak detection, provided sufficient noise levels are generated.

Ideal Locations
●areas where the acoustic emission levels are highest and most consistent
●where the material impact is greatest
●areas closest to the point of leakage (e.g. valve body)
●closest point to source of cavitation (e.g. pump body)
Conditions to Avoid
●non-metallic surfaces, as these tend to attenuate acoustic emission levels
●pipes with non-metallic liners as these tend to attenuate acoustic emission levels
Conditions to Consider
●joints and interfaces attenuate the acoustic emission levels.
●minimal temperature variation where acoustic emission levels are weak.
●location should provide sufficient response time in alarm or control circuit. e.g. loss of bearing
lubrication, plug chute detection.

Note
•
To ensure the most ideal location, test the SITRANS AS100 by clamping the Sensor to
the application, and running a trial period to determine the system's performance. The
acoustic emission level can be monitored by a voltmeter across the analog output. Refer
to Interconnection (Page 21).
•
Coating the contact surfaces with grease enhances the propagation of acoustic emissions
to the Sensor.

Note
•
If welding, weld must be a continuous bead. Tacking does not provide sufficient
acoustical coupling.
•
Do not arc weld on equipent connected to a SITRANS AS100. Remove the SITRANS
AS100 or disconnect electrically to avoid current flowing through the sensor.
•
If gluing, use Loctite 326 adhesive, or equivalent. Follow manufacturer’s instructions to
ensure proper adhesion.
