Abstract

The invention discloses an on-line liquid viscosity and density detection probe. The on-line liquid viscosity and density detection probe is characterized by comprising a coil framework, wherein an upper end cover and a lower end cover are respectively arranged at the two ends of the coil framework; a cavity defined by the upper end cover and the lower end cover of the coil framework serves as a measurement room; the upper end of the measurement room is opened to serve as a liquid flow inlet; the lower end of the measurement room is sealed by a lead seat; a movement floater made of a magnetic conducting material is arranged in the measurement room; an ultrasonic sensor is mounted on the lead seat at the lower end of the measurement room; coils are wound on the outer wall of the coil framework. The on-line liquid viscosity and density detection probe is simple in structure and convenient to mount, solves the problems existing in on-line liquid viscosity and density measurement, can achieve an automatic cleaning function, is durable, can be added with a temperature sensor to prevent measurement from being influenced by temperature and is high in measuring accuracy.

Description

technical field [0001] The invention relates to an industrial detection device, in particular to a liquid viscosity density on-line detection probe. Background technique [0002] Viscosity and density are important performance indicators of liquids. The existing viscosity measurement methods include capillary method, falling ball method, rotation method and vibration method, etc. Density measurement is commonly used by densitometer method. [0003] For example, Chinese Patent No. 201320739700.3 discloses a liquid viscosity detector, which ensures the accuracy of measurement by installing a stirring device and a temperature sensor in the container, and installing a detection device in the lower part of the container, and using a photoelectric gate for measurement. [0004] In the existing technology, there are many similar patented technologies to achieve viscosity detection. On the one hand, most of the methods are offline measurement, which is difficult to meet the requirem...
