Automatic Samplers


Automatic Samplers

Accurate, representative samples begin with the right equipment. With individual design and component construction, InterSystems’ Automatic Samplers adapt readily to your particular application, regardless of capacity, layout or material - all backed by decades of industry success. An in-line automatic sampler - or primary cross-cut sampler - is frequently installed in place of a section of spouting as a 45° or 90° model. As material flows through the sampler, a pelican diverter with a leading-edge opening traverses the stream and extracts a representative sample. A mechanical divider receives the sample by gravity and then passes through a continuously oscillating swing valve that reduces the sample and distributes it into a one, two or three sample adapter determined by the flow rate, installation, and frequency of the samples. Sample delivery units are used to transport bulk samples from one point to another, reducing labor costs with efficient motor operation of blower and air lock. A variety of automatic controls and collection systems options offers more opportunities to create the sampling system that best fits your needs.

Key Features

Collection Systems

Collection systems are available as lockable cabinets or hopper style. With an automated collection system such as the Rotating Indexing Cabinet, you can receive and store samples virtually unattended. An adjustable timer is pre-set to determine the number of samples (or duration) per container. When it is time, the system automatically positions the 8, 16 or 24 sealed containers for the next filling. Other collection systems provide for automated or manual bag filling.

Mechanical Dividers

Mechanical dividers divide the extracted sample from the primary sampler down to a workable size while allowing the excess to return to the main material stream. These dividers are designed to maintain representative sample integrity and accuracy with lower handling costs. Manufactured in four models: MD 100, MD 200, MD 300 and MD 1000, with one, two or three sample discharges. MD 50/50 Sample Splitter also available.

Pneumatic Sample Delivery Units

Sample delivery units are used to transport bulk samples from one point to another, reducing labor costs with efficient motor operation of blower and air lock. Units are available in 2” and 3” (50.8 and 76.2 mm) diameter sizes. Use is dependent upon volume of sample and distance to be transported.

Automatic Controls

InterSystems control packages are available to suit any sampling control application. The standard units allow manual and automatic sampling modes and contain all the essential components to adjust and control the timing of sampling operations. These units can handle a wide variety of voltages and frequencies and can be constructed for most environments.

Expor-ter Cross-Cut Sampler (GCE)

High Volume, Heavy Duty Operation in 45° Or 90° Spouts/Chutes

This sampler is constructed of 7 gauge steel with 5/16” (7.94 mm) abrasive resistant lining. Standard features include A.R. steel slide plate, slide plate cam followers, fabricated box slide plate, bolt-in pelican, heavy duty drive, large inspection door and flip out dust seals. Drives can be electric, pneumatic or hydraulic.

Rotary Cross-Cut Sampler (GRA)

Vertical (90°) Gravity Flow Spouts/Chutes

The internal pelican traverses through the material stream to obtain an accurate sample and moves out of the stream when not taking a sample. The unit features dust tight design with heavy gauge steel, wear resistant liners and replaceable cutter blades on the pelican. Pelicans can be either 45° or 60° styles depending upon the flow characteristics of the material. Drives can be electric, pneumatic or hydraulic.

Gravity Chute Sampler (GP)

Inclined or Vertical 45° or 90° Applications

This Sampler features easy installation and simple operation with one moving main part. Adjustable sampling frequency with automatic or manual operation is standard. When activated, the slotted, stainless steel sample tube enters the product stream and takes a sample. The sample then flows by gravity to a sealed container. When not sampling, the sample tube is retracted and out of the product stream. Drives can be electric, pneumatic or hydraulic.

Belt End Samplers

All models feature sample delivery by gravity or pneumatics and are custom designed to meet your operation’s needs. Features include internal access for serviceability, rugged heavy gauge steel construction, heavy duty drive components, abrasion-resistant liners at all wear points and replaceable cutter blades. These models are designed as “drop-in” models or as complete discharge hoods. The pelican rests behind the dust seal and out of the material stream when not operating. Drives can be electric, pneumatic or hydraulic.

Pneumatic Line Samplers (PS)

Model PS Samplers are designed for applications with free flowing materials, ranging from flour and microscopic powders to large granules and pellets or heavy viscosity liquids with solid suspensions. The PS collects accurate samples from gravity or pneumatic conveying systems (positive or negative, dense or dilute phase) and may be mounted in vertical or horizontal lines, spouts or chutes. The sample tube enters the product stream, collects a sample, retracts and deposits the sample by means of a stainless steel polished auger to the collection system. The close-tolerance polished auger provides for excellent clean-out. Standard construction includes an aluminum seal housing, stainless steel sample tube and auger and Teflon pressure seals.
