Instrument for the continuous measurement of viscosity, especially of bitumens |
摘要 |
The instrument comprises a viscometer for a product such as bitumen and a pump for transferring the product to a flat wall-type heat exchanger. A channel formed in the heat exchanger wall is brought to an adjustable temperature and the channel output is connected to the viscometer. A probe for measuring the temperature of the product is placed within the viscometer, the temperature being adjusted to an index value within a predetermined range by means of a regulator for varying the pump output and controlling the temperature of the heat-exchanger wall.
