Auger sampler ST29

Application

These simple sampling systems take continuous, representative and reproducible samples of any quantity from static, sliding or free-falling solids with particle sizes below 4 mm. After extraction the sample drops into any collection system attached to the outlet with a 1.5″ Tri-Clamp connection.

The unit is easy to install and works reliably. The sample quantity is set freely by the operating time. With a drive and suitable control, sampling can be time-, volume- or event-proportional.

Function

A stainless steel wire helix conveys the product through the sampling tube, and the sample drops from the outlet into a sample container. The helix is driven by hand crank (type M), a pneumatic gear motor (type A) or a 24 V electric motor (type E). Product left in the housing is cleared from the tube by running in reverse, so every sample is fresh.

Mounting and installation

The supplied Tri-Clamp flange is welded into the wall of the pipe or chute, and the sampler is fixed to it with a clamp. A sample collection system can be connected to the outlet. For pressure or vacuum applications, fit a shut-off valve between sampler and collection container.

Advantages

• Suitable for light powders and granules
• Easy to install: one flange is enough
• Easy to clean
• Any sample container can be adapted
• Very low overall height
• Excellent value for money
