Measurement apparatus with horizontal specimen device for ultrasonic liquid penetration measurement overcomes inability of conventional arrangements to reproduce process conditions

摘要

The measurement arrangement has a plate (1) with an ultrasonic transmitter (3) mounted on it and a parallel plate (2) with an ultrasonic receiver (4) mounted in a mechanical arrangement. At least one of the plates with its sensor is mounted to move on an axis perpendicular to the sensor surface.- DETAILED DESCRIPTION - The paper specimen (6) is mounted on one plate and the test liquid (7) applied to the other plate. Contact is made between the specimen and the liquid by pressing one plate on the other in parallel
