Free flowing powders

The SPV automatic sampler can be used for sampling free flowing powders, granules or flakes out of down spouts. It consists of a pipe section matching the diameter of the conveying line with a permanent, inclined sampling tube. 

Due to the angle of the tube, the sampled product must be free flowing. The tube has a longitudinal sample slot on one side. When not in use, the slot is facing down.


Working principle

When the sampler is activated, the pneumatic torque cylinder rotates the sample tube until the sample slot faces upwards. (1) 

Material enters the sampler through the sample slot and gravity causes the sample to slide down into the sample jar. After sampling, the sample tube is rotated back until the sample opening is facing down. (2) 

Material will pass the sample tube without being extracted.

SPV samplers can be supplied including a control unit, consisting of a cabinet with Siemens Logo PLC and fuses, switches, motor protector and frequency converter. The cabinet is internally wired and tested and standard suitable for a non-classified zone. This control unit is optionally available conforming to ATEX 2014/34/EU.
