    摘要： A rheometer (10) includes a holder assembly (14) for coupling a test specimen (50) to a motor assembly (20) to effect rotational strain in the test specimen (50) while enabling the determination of axial displacement effected by the test specimen normal to the direction of the rotational strain, the holder assembly (14) having a first member (34) coupled to the test specimen (50), a second member (16) coupled to the motor assembly (20), and a suspension arrangement (14) coupling the first member (34) with the second member (16) for simultaneous maximum resistance to relative rotational displacement between the first and second members and minimum resistance to relative axial displacement between the first and second members. Information pertaining to the axial displacement, and to the temperature of the test specimen, is obtained through measuring circuits (128, 132) which include sensors (120, 150, 160) placed in moving component parts of the rheometer.

    摘要： The process meter serves for the measurement of a physical process parameter of a medium contained in a process vessel or flowing in a process line and comprises a meter probe (10), with a sensor arrangement (60), providing measured signals (s1, s2) and a meter electronics device (50), connected to the meter probe (10). The sensor arrangement (60) comprises a primary sensor element (17), reacting to the physical process parameter, also in particular, changes in the physical process parameter and provides a measured signal (s1), dependent on the physical process parameter. The sensor arrangement (60) further comprises at least one temperature sensor (40), arranged in the meter probe (10), which records a local temperature (T1) in the meter probe (10) and provides the sensor arrangement (60) with a measured temperature signal (θ1) which represents the temperature (T1) in the meter probe (10). The meter electronics device (50) generates an instantaneous measured value (X), representing the physical parameter, using the measured signal (s1) and using a correction value (K1) for the measured signal (s1). The meter electronics device (50) determines said correction value (K1), by means of the curve with time of the one measured temperature signal (θ1), such as to take account of the temperature values recorded by the temperature sensor (40) in the past. According to the invention, temperature generated errors in the measured signal are well compensated by said process meter, even with a fluctuating transition range for the temperature distribution within the meter probe and particularly with the application of only a few temperature sensors.

    摘要： On-line rheological measurements are made utilizing a rheometer (20) of the type in which a first metering pump (24) delivers diverted melt from a process main stream to a capillary passage (36) and a second metering pump (34) returns the diverted melt from the capillary passage to the process main stream and the viscosity of the diverted melt is measured by controlling the rate of flow of the melt through the capillary passage to maintain constant the pressure drop between spaced apart locations along the capillary passage and measuring the temperature of the melt in the capillary passage. The measurements may be made while controlling the speed of the second metering pump independent of the speed of the first metering pump to maintain the pressure at the exit of the capillary passage essentially constant. A parallel flow passage (70) has an inlet placed between the first metering pump and the entrance to the capillary passage, in close juxtaposition with the entrance, and an outlet placed between the exit from the capillary passage and the second metering pump, and a valve (76) in the parallel flow passage is operated so that diverted melt selectively is passed through the parallel flow passage to attain a relatively quick response and relatively short residence time of the diverted melt in the rheometer.
