- Other materials on request
Non contact parts: - 304 grade stainless steel
- Other materials as required.
The Pneumatic Inline Powder Sampler is specially designed and engineered so that powder is kept out of the bearings by a special flexible membrane - this means the sampler will not jam
The sample is collected in a cup and so is not physically altered by the sampling process
When the sampling cup is retracted, the full bore of the downpipe is available for powder flow
Made from FDA acceptable materials and is easy to strip down for cleaning
When the sampler is not in use the full bore of the downpipe is
available for powder flow.
Sampling
The sampling cup is extended into the downpipe to catch the
product as it falls.
Discharging
The sampling cup is then retracted and inverted. The powder
sample falls down the discharge chute to where it is collected
Confirm that there is an earthing route from the cup to the Tee Piece (see section 5.3)
Confirm that there is an earthing route from the Tee Piece to the downpipe (see section 5.4)
Visually check that the sampler is making a good seal with the inside face of the product chute when
in the extended and retracted positions.
* Polymer components must be viewed as consumable parts and replaced at the first signs of wear.
Lubrication schedule
There are no components on this sampler assembly which require lubrication.
5.3 Earthing (Grounding) Check – Inside Sampler
Ensure that the resistance between the cup and the Tee Piece is less than 1 Ohm.
The FreeGlide is fitted with phosphor bronze bearings; these provide a constant metal to metal earthing path
through the equipment. There is no adjustment possible by the the customer.
If the resistance is greater than 1 Ohm, then the inner workings of the sampler are electrically isolated.
The device must not be reinstalled until it has been properly investigated.
Earthing (Grounding) Check – to surrounding equipment
Ensure that the resistance between the Tee Piece and the Downpipe (i.e.
surrounding equipment) is less than 1 Ohm.
The automatic sampler uses pneumatics to extend and retract the cup and to rotate it. Electrical sensors are used to monitor the position of the automatic sampler .
