    ACOUSTIC SENSOR

    Features Non-Mechanical: Doesnt foul up or wear out

    Noninvasive: Doesnt break, leak, or clog

    Simple Mounting: Doesnt take long or require shutdown

    Acoustic Emission Detection Technology: Reliably detects material flow/no flow conditions

    Two Alarm/Control Relays and 0/4-20 mA Output: Will easily connect to your process

    Reliable, Continuous Protection for Bulk Solids FlowThe SITRANS AS100 sensor prevents problems in solids flow processes

    caused by abnormal flow, sudden blockages, product absence, or equip-ment failure, such as burst filter bags. It reacts instantly to changes in flow of pellets, powders, or most bulk solids in pipes, chutes, vibratory feeders, pneumatic conveyors, and gravity flow systems.

    Any sudden blockage that prevents product flow or any rupture that increases flow as product escapes from a pipe or bag is immediately detected by the AS100. This enables you to take early preventative ac-tion, avoiding expensive damage.

    Early Warning of Flow ProblemsThe friction and impact of bulk solids flow in pipes, chutes, and con-

    veyors all generate high frequency sound waves noises that are often inaudible to the human ear. The SITRANS AS100 detects deviations in these sound waves caused by changes in solids flow rates and warns of impending problems.

    Operation Unaffected by Plant Environment NoiseThe AS100 uses unique acoustic emission technology to detect high

    frequency sound waves generated by equipment and materials in mo-tion. These sound waves travel readily through solids materials, but are strongly attenuated when traveling through air. Consequently, the AS100 is immune to interference from airborne noise and low level structural vibration, providing a noninvasive method of process monitoring. Because the AS100 operates in a high frequency broadband, it is immune to com-peting background noise generated by machines and other processes. Audible noises and low frequency vibrations are screened out.

    Simple, Low-Cost InstallationThe noninvasive sensor can be installed without any shutdown of

    process or equipment. In minutes, the compact unit can be attached to a flat surface, pipe, flange, elbow, or joint, where acoustic emission levels are potentially highest.

    The light-weight unit weighs only one pound and is easily positioned. A range of installation option are available to suit your needs. Installation can be via a clearance hole and bolt, drilling and tapping, mounting disc, or an extension tab. The unit can be screwed in, bolted in, or bonded in place. Once installed, simply connect the power supply and alarm output and set the alarm level, and the unit is fully operational.

    24-Hour Protection in Tough EnvironmentsWith no moving parts and a type 304 stainless steel housing sealed

    against dust and moisture, the AS100 provides continuous protection around the clock and requires little or no maintenance.

    Because the AS100 is mounted outside the process, it is completely noninvasive. In hazardous or hygienic food environments, this is a great advantage as there is no need for constant cleaning and concerns about product contamination are eliminated. The SITRANS AS100 is also unaf-fected by abrasive applications.

    Acoustic Sensor and Controller for Bulk Solids Flow

    The standard sensor operates effectively from -4 to 176 F (-20 to 80 C), with extended temperature options offering sensing from -40 to 185 F (-40 to 85 C) or -40 to 257 F (-40 to 125 C).

    Field-Proven DetectionThe SITRANS AS100 monitors a wide range of granular and bulk solids

    materials, including:

    Sugar (granulated or powder) Wood chips Coal (slugs to dust) Cement Polyethylene pellets Grain Cocoa beans Sand Fiberglass

    Applications include:

    Solids flow sensing Filter monitoring and Flow/no flow, high flow/low flow switching Inflow blockage detection Burst filter bag detection Cyclone blockage detection Route verification

    Ease of UseThe AS100 system combines a highly sensitive acoustic sensor with

    easily set up controls. Powered by 20 or 30 VDC, the sensor provides a DC analog voltage that can be monitored by the dedicated SITRANS CU 02 control unit, or a PLC that accepts 0-10 VDC input signals.

    Control OptionsWith a SITRANS CU 02 control unit, the system can be readily configured

    for setpoints indicating such conditions as high flow, low flow, or no flow, or it can be added to a control loop via a 4-20 mA output.

    Two relays are fully programmable and independent of each other, and can be used to operate an alarm or switch device. The control unit can be mounted up to 1500 feet from the sensor.

    The signals are amplified and processed by the AS100 sensor to provide the levels of acoustic emission activity as a function of time.

    With a CU 02 as part of the system, two relays, an LCD, and 4-20 mA outputs are provided. The sensor output can also be fed directly to a PLC accepting a 0-10 VDC signal.

    The sensor can also be operated independently of the control unit by providing an external power supply.

    The output is fed into a control panel, chart recorder, data logger, or programmable logic controller with a suitable input.
