ABSTRACT:
A sampler apparatus includes a housing which is adapted for mounting on pressurized conveying lines and a remotely mounted control unit. The housing includes a sampling probe which is extended from the housing to enter the conveying line and collect a sample of material flowing in the conveying line and then is retracted into the housing. An auger is provided to clean out the sampling probe when in the retracted position and force the sampled materials into a discharge tube. The control unit controls the timing of the extension and the retraction portion of the operating cycle.
