ABSTRACT:
A sampling apparatus is characterized by a sampler coupled to a product-containing vessel by an adapter. The sampler has a bore received in the adapter and leading to an opening in the vessel. A plunger in the bore has an annular recess intermediate its ends. The plunger is reciprocated forward in the bore to project the recess through a forward outlet from the bore and through the vessel opening into the vessel to receive a sample of liquid therein. The plunger is then reciprocated rearward to retract the recess from the vessel and into the bore to a sample delivery point. When the plunger is in the sample delivery position, a relatively long portion of the sampler bore exists between the front of the plunger and the forward bore outlet. The sampler has two motors. A first one of the motors reciprocates the plunger during sampling cycles between its sample receiving and sample delivering positions. A second one of the motors operates when the sampler is idle to move the plunger to a parked position where its forward end is close to or at the forward outlet from the sampler bore. In its parked position, the plunger closes the forward outlet from the bore to prevent product from entering, stagnating in and clogging the forward end of the bore and thereby rendering the sampler inoperative.
