Continuous cold cranking simulating monitors. |
摘要 |
<p>Apparatus for unattended retrieval of samples of material to be tested for viscosity provides substantially continuous monitoring capability for a blending plant. A single device is used for both retrieving the samples from a pipe (10) conveying the material and for delivering the samples to a measuring chamber of a viscometer. The device, such as a pump (12, 14) or a solenoid operated valve, is controlled by a sequence timer (16) programmed to generate a timed sequence of signals. Preferably, the device is operated to provide a new sample to the viscometer when the measuring chamber is being heated, thereby displacing the previous sample without requiring a cleansing agent.</p> |
