Description

Technical Field

[0001] This utility model relates to the field of oil sensor technology, and in particular to an oil viscosity sensor and an oil viscosity detection system. Background Technology

[0002] With the increasing level of industrial automation, sensors are playing an increasingly important role in automated control systems. As a source of information for monitoring, sensors have become a crucial means of industrial automation, and the data they detect can support the efficient, stable, and healthy development of industrial automation. Viscosity sensors, as a type of sensor for detecting oil viscosity, can reflect changes in kinematic viscosity in oil in real time, providing important criteria for judging changes in oil quality. They have broad application prospects in industrial hydraulic lubricants and the petroleum industry.

[0003] Because viscosity sensors need to be inserted into oil pipelines, the impact of the oil inside can easily damage them. To protect the sensors, a common practice is to install a protective cover around the sensor with small holes for oil to flow in and out. However, this method can prevent the oil inside the protective cover from exchanging with the oil inside the pipeline, resulting in the inability to obtain timely viscosity data and inaccurate viscosity readings from the viscosity sensor.

[0004] Furthermore, the viscosity of the oil is related to temperature. A common approach is to install a temperature sensor separately on the pipeline to measure the temperature of the oil inside the pipeline, but this method increases the workload of installation.

[0005] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0006] This invention provides an oil viscosity sensor and an oil viscosity detection system, which solves the drawbacks of existing methods for detecting oil viscosity data that are inaccurate or have large deviations.

[0007] The technical solution of this utility model is as follows: An oil viscosity sensor is provided, comprising: a main component, and a probe portion and a control portion respectively installed on both sides of the main component; the probe portion includes: a probe cover connected to the main component, and a viscosity sensor, a temperature sensor, a magnetic coil, and a probe core disposed within the probe cover; the probe cover is provided with an oil inlet hole, the probe core is disposed inside the magnetic coil, and the probe core is disposed on one side of the oil inlet hole with a size larger than the oil inlet hole; the control portion is electrically connected to the magnetic coil, the viscosity sensor, and the temperature sensor.

[0008] The control unit controls the magnetic coil and receives data from the viscosity sensor and temperature sensor. The probe housing protects the viscosity sensor, temperature sensor, magnetic coil, and probe core. The viscosity sensor detects the viscosity of the oil, and the temperature sensor detects the temperature of the oil. Under the control of the control unit, the magnetic coil moves elastically up and down, allowing the oil inside the probe housing to exchange with the oil in the pipeline through the inlet. This ensures that the viscosity detected by the viscosity sensor is the same as the viscosity of the oil in the pipeline, guaranteeing accurate and virtually error-free viscosity data. Furthermore, since the temperature sensor is also located inside the probe housing, there is no need to install a separate temperature sensor, reducing installation workload.

[0009] Furthermore, the main component includes: a mounting plate, a mounting platform connected to one side of the mounting plate; the probe cover is connected to the mounting platform, and the control unit is connected to the other side of the mounting plate.

[0010] Furthermore, the viscosity sensor and temperature sensor are mounted on the main component.

[0011] Furthermore, a coil groove is provided inside the probe cover, and the magnetic coil is disposed in the coil groove, which facilitates the fixed installation of the magnetic coil.

[0012] Furthermore, the probe cover is connected to the main component by a threaded connection.

[0013] Furthermore, the control unit includes: a cover connected to the main component, a power board and a control board disposed within the cover, and cables passing through the cover and electrically connected to the power board and control board; the power board and control board are respectively electrically connected to the viscosity sensor, the temperature sensor, and the magnetic coil. The control board is used to control the power supply to the magnetic coil, thereby enabling the probe to move up and down, and simultaneously, the control board is used to receive data detected by the viscosity sensor and the temperature sensor.

[0014] Furthermore, the control unit also includes a gland connector mounted on the cover, through which the cable passes into the cover.

[0015] Furthermore, the control unit also includes a sealing ring disposed between the gland connector and the cover.

[0016] Furthermore, the cover is threadedly connected to the main component.

[0017] Furthermore, this utility model also provides an oil viscosity detection system, including: the aforementioned oil viscosity sensor, controller, cloud platform, and user terminal; the controller is electrically connected to the oil viscosity sensor via a cable, the controller is communicatively connected to the cloud platform, and the cloud platform is communicatively connected to the user terminal.

[0018] By adopting the above solution, this utility model provides an oil viscosity sensor and an oil viscosity detection system. By placing the coil and probe core inside the probe housing, rapid exchange of oil within the housing is achieved, ensuring that the viscosity detected by the viscosity sensor accurately reflects the viscosity of the oil in the pipeline. This guarantees accurate and virtually error-free oil viscosity data. Furthermore, by also placing the temperature sensor inside the probe housing, a dedicated temperature sensor is eliminated, reducing installation workload. Attached Figure Description
