R Powder Sampler
This pneumatically operated automatic sampler is specifically designed to provide automatic sampling of powders and granules from hoppers and conveying lines.
The body is constructed from aluminium, the sampling tube from 316 stainless steel and the seals from PTFE. It is operated by a pneumatic cylinder to VDMA cylinder and as it is completely air driven, the sampler is explosion proof.
A sample is taken when on receiving a signal from the controller, the tube extends into the flow of material. The air driven auger motor is simultaneously started. The tube will remain in this position for the preset time, continually collecting the sampled product. The timing device is flexible and easy to reset, allowing the correct quantity of sample to be collected each time.
When the preset time is reached the tube retracts from the conveying line, the motor however, continues to operate to enable all the sample remaining in the tube to be purged. This is vital to ensure that each sample taken is a true and precise representation of the product.
When the sample tube is retracted there is no obstruction to the flow of material and the unit is sealed.
