Description

Technical Field

[0001] This utility model relates to the field of liquid level switch technology, and more specifically, to an integrated liquid level switch with temperature measurement function. Background Technology

[0002] Existing integrated level switches are float-type, but float-type level switches have the disadvantage of being prone to material sticking, making them unsuitable for the lithium battery industry where high-viscosity materials are used. Currently, the lithium battery industry often uses level switches and temperature measuring instruments, requiring at least two instruments to measure the material's level and temperature separately. This not only wastes space but also increases manufacturing costs. Summary of the Invention

The liquid level sensor is used to detect the liquid level information of the material in the container, and the temperature sensor is used to detect the temperature information of the material in the container.

[0006] The junction box includes an electrical connection port, an LCD screen, a housing, and a digital circuit board.

The LCD screen is used to display the liquid level information and temperature information of the material in the container in real time. One end of the housing is provided with the electrical connection port, which is connected to an external electrical control cabinet to output the liquid level information and temperature information of the material in the container to the electrical control cabinet.

[0007] Furthermore, the electrical connection port uses a gland connector.

[0008] Furthermore, the digital circuit board includes a transmitter module, which is used to convert the PT100 signal emitted by the temperature sensor into a current signal in real time and output it to the liquid crystal display screen, which displays the temperature information of the material in the container in real time.

[0009] Furthermore, the liquid level sensor has a hollow structure, and the temperature sensor is placed inside the liquid level sensor.

[0010] Furthermore, the connector includes a nut, and the top end of the sensing rod is threadedly connected to the connector and then threadedly connected to the bottom of the junction box.

[0011] The integrated liquid level switch with temperature measurement function provided by this utility model has the following advantages: (1) It combines the functions of real-time detection of liquid level and temperature, replacing two instruments with one instrument, reducing costs and space requirements; (2) Compared with the original liquid level gauge, this integrated liquid level switch is more sensitive.

Figure 1-3 As shown, the integrated liquid level switch with temperature measurement function includes a junction box 1, a sensing rod 2, and a connector 3. The junction box 1 is connected to the sensing rod 2 through the connector 3.

[0020] The sensing rod 2 includes a liquid level sensor 21, a temperature sensor 22, and a mounting connector 23. The mounting connector 23 is installed on the container. The liquid level sensor 21 is used to detect the liquid level information of the material in the container, and the temperature sensor 22 is used to detect the temperature information of the material in the container.

[0021] Junction box 1 includes an electrical connection port 11, an LCD display screen 12, a housing 13, and a digital circuit board 14. The digital circuit board 14 is placed inside the housing 13, and the LCD display screen 12 is soldered onto the digital circuit board 14. The LCD display screen 12 is used to display the liquid level information and temperature information of the material in the container in real time. One end of the housing 13 is provided with an electrical connection port 11, which is connected to an external electrical control cabinet to output the liquid level information and temperature information of the material in the container to the electrical control cabinet.

[0022] Preferably, the electrical connection port 11 uses a gland connector.

The liquid level signal is a digital signal, and the temperature signal is an analog signal.

[0027] The liquid level sensor 21 detects the liquid level signal of the material in the container in real time and sends the detected liquid level signal to the digital circuit board 14. When the digital circuit board 14 determines that the liquid level of the material in the container has reached a certain liquid level height, it controls the LCD screen 12 to display the ON signal status. When the digital circuit board 14 determines that the liquid level of the material in the container has not reached a certain liquid level height, it controls the LCD screen 12 to display the Off signal status.

[0028] Temperature sensor 22 detects the temperature signal of the material inside the container in real time and sends the detected temperature signal to digital circuit board 14. The transmitter module in digital circuit board 14 converts the temperature signal (PT100 signal) into a current signal and outputs it to LCD screen 12. LCD screen 12 displays the temperature of the material inside the container in real time.

[0029] This utility model provides an integrated liquid level switch with temperature measurement function, which combines liquid level measurement and temperature measurement functions.
