II. GENERAL INFORMATION
2.1 System Description
The GSS-U Sampler is designed to collect a representative sample of granular, flake, powder, or other materials
in a gravity conveying line or from a hopper tank. Figure 2-1 illustrates a typical GSS-U Sampler application.
Sample collection is initiated in response to either an operator's manual command or a signal automatically
generated by controller logic, usually time-based but which could also be volume or quantity based. A sample
cycle begins when an electric motor operating through a right angle gear reducer rotates the drive housing input
shaft. The clutch solenoid, which energizes at the same time the motor starts, allows the slotted sampling tube
(auger tube) in the product line to rotate through one revolution to collect a sample of the material. As the auger
tube rotates the sample auger also is turning and continues to auger material out of the auger tube for a period of
time after the auger tube stops rotating. The sample then falls down and out the 2.00" (51mm) OD discharge tube
to the desired sample collection point, at which point an Inter
s
ystems SCS Sample Collection System (optional)
may be installed.
