SAMPLING DEVICE |
摘要 |
(57) The invention relates to a sampling device for taking a sample particularly from a fluid substance, such as paper pulp. The sampling device comprises a body (1) to be fixed at a process interface and an element (2) mounted in connection with the body for effecting a sampling procedure. For a sampling procedure, said sampler element (2) is adapted to be shifted to an operative position into communication with a fluid substance through an opening (7) or a like made in body (1). In its inoperative position, said sampler element (2) cuts off communication between said opening (7) of body (1) and a process (P). The sampler element (2) includes a chute-like member (3) which, in the inoperative position of sampler element (2), said chute-like member (3) being in a position partially extending from the body into process (P), defines by its inner surface (32) together with a portion of the rim of said opening (7) in body (1) a fluid substance inlet passage (8) into said body (1) during a sampling operation.
