    The Cup Sampler (CS) extracts an increment/cut from a free-falling flow of bulk material in a vertical duct.

    Accurate sampling is achieved through precise control of the pneumatic system, which allows time-, volume-, or event proportional samples to be taken.

    It consists of a piston-mounted cup that is led into the falling material stream for sampling. When activated, the cup traverses the material stream and collects the sample. When a sample has been collected, the cup retracts into the housing, tilts, and discharges the material through the sample outlet.

    What‘s the benefit?

    • With its compact size and standard triclamp flanges, the CS is designed for quick and easy installation.
    • As opposed to manual grab sampling, the CS provides a fully automated sample and eliminates tedious and hazardous work.
    • The control system ensures that the CS continuously collects samples with correct timestamps.
    • The CS is enclosed in a cover housing to avoid external cross-contamination.
    • Well suited for harsh environments and rough abrasive materials. Which is often seen in the fertilizer industry.
    • The CS disassembles easily for fast inspection and maintenance.
    • The cup is parked in the CS housing and only interrupts the material flow during sampling, keeping the cross-section of the vertical duct fully intact.

    How does it do it?

    The CS consists of a piston-mounted cup that is led into the falling material stream for sampling. A robust pneumatic drive system controls this motion with high precision.

     

    When activated, the cup traverses the material stream and collects the sample. When a sample has been collected, the cup retracts into the housing, tilts, and discharges the material through the sample outlet.

     

    The entire system is enclosed in a protective housing to prevent external contamination. In resting position, the cup is parked above the sample outlet and the connection to the material stream is sealed. This prevents non-sampled material from entering the system and keeps the cross-section of the vertical duct unobstructed.

     

    The CS is installed with a TC flange welded into the wall of the vertical duct. The sampler is attached to the flange using a Tri-Clamp, allowing easy disassembly for cleaning and maintenance. A sample collection system, such as a bottle adaptor or bag holder, can be connected to the sample outlet.

    Variants and Options.

    Mark & Wedell’s Cup Sampler is available in variants to suit low to high volume sampling for pipes from 100mm up to 500mm. All designed for pneumatic control to ensure consistent, reliable, and maintenance-friendly operation.

     

    • The compact CS-50 versions deliver 50 ml per stroke, ideal for frequent, low-volume sampling.
    • The CS-150 versions deliver 150 ml per stroke, ideal for medium-volume sampling.
    • The CS-300 versions handle 300 ml per stroke, suited for high-volume sampling.

     

    All variants are made from high-grade stainless steel and feature a modular design for easy integration, maintenance, and customization.

     

    Option 1.

    The M&W control cabinet can exchange signals with the client’s control system.

     

    Option 2.

    The CS can be delivered with a support structure.

     

    Option 3.

    The CS can be delivered with a bottle adaptor.

     

    Option 4.

    The CS can be delivered with a bag holder.

     

    Option 5.

    The CS can be delivered with a duct that can lead the mainstream material further in the process stream.

     

    Important note

    The Cup Samplers can be calibrated with respect to the client’s material(s) and local sampling conditions. M&W offer clients a facility for quantitative assessment of the performance of CS on the  client’s own material(s).
