automatic industrial sampling

PRT

The PRT belt end sampler model from Intersystems provides representative and repeatable samples, employs very simple and reliable operation and uses minimum headroom. It samples fines, small or large particles and works with abrasive materials.

Mounting may be in chutes, hoppers, at belt-end or head chutes. When activated, a slotted sample tube enters the product stream with the slot facing down. While full y extended, the sample tube rotates 270 degrees, taking a representative sample through the product stream. The sample tube then retracts out of the product stream, into the sampler housing and deposits the sample into the discharge. The sample tube can be driven pneumatically or hydraulically.

SAMPLE TUBE OPERATION

At rest & retracted – tube then begins to enter product stream at the 6 o’clock position
As the tube moves through the product stream it rotates from the 6 to 3 o’clock position while collecting sample
After collection, tube retracts back into the PRT sample
Retracted, the tube rotates back to the 6 o’clock position & releases sample into the chute – ready to repeat
