Sample quantity extracted is determined by cutter angle and rotation speed. Rotation speeds are set to maintain standards for cutter speed through
the material being sampled, according to radius of cutter, to avoid sample bias. Cutter opening for fine solids is adjustable up to 18 degrees (five percent extraction) by means of simple mechanical
brackets. A hinged inspection door with safety switch is provided to access the brackets for cutter angle adjustment. Cutter angle is selected to obtain the proportion of sample specified.
Cutter blades are replaceable, fabricated from type 304 stainless steel or other wear resistant material as specified. Cutter edges are inspected
and adjusted through a removable access plate. Stainless steel cutter edges are replacable.
Motor drives are typically 1/3 HP or 1/2 HP according to sampler model required and application requirements. A timer-starter control unit model
PB-200 series is available for stand-alone operation of a PRV sampler. Alternatively, the sampler can be operated from a remote or centralized control system, or a programmed logic controller.
