Sampler apparatus
First Claim
1. A sampler apparatus for sampling materials in a pressurized conveyor line comprisinga housing,attachment means for attaching said housing to said pressurized conveyor line,hollow sampling probe means mounted in said housing, with said sampling probe capable of translation to an extended position relative to said housing and a retracted position, with said sampling probe when in said extended position projecting into said pressurized conveyor line, and with said sampling probe when in said retracted position retracted into said housing, with said sampling probe means including an inlet aperture and a discharge aperture,probe drive means for reversibly driving said sampling probe from said retracted position to said extended position,auger means mounted in said sampling probe, means for cleaning said auger means when said sampling probes means is in said retracted position,auger drive means mounted on said housing for driving said auger drive means, and control means for controlling the operation of said probe drive means and said auger drive means, said housing including a purge port and said sampling probe including a purge aperture and with said purge port and said purge aperture substantially in alignment when said sampling probe is in said retracted position.

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.
