[0002] A transmitter is a device used to convert one form of energy into another. It can convert mechanical energy, electrical energy, thermal energy or other forms of energy, and is commonly used in various applications in industrial production, such as sensors, electronic equipment, instrumentation, etc. Transmitters can convert raw signals into signals that can be monitored, recorded or controlled, and play an important role in industrial control systems.

[0003] Generally, before the transmitter is put into use, it is necessary to perform filling and testing on the transmitter through a corresponding liquid filling device to determine whether there is leakage in the welding of the preceding components of the transmitter during the production process, whether the high and low sides of the sensor are connected, eliminate the influence of the component tolerance range on the medium filling, and whether the intermediate elastomer meets the requirements of the drawing. However, in the prior art, general filling devices are unable to fill transmitters of different models, and the adjustment is complicated, resulting in high investment costs and low detection efficiency.

[0036] The invention provides a transmitter quantitative filling system.

[0037] In an exemplary embodiment, a transmitter dosing system includes:

[0038] A liquid supply module, which is connected to the transmitter 3 and is used to introduce the detection medium into the transmitter 3;

[0039] A control module is arranged between the liquid supply module and the transmitter 3. The control module controls the amount of medium filled into the transmitter 3 by the liquid supply module. The control module includes a detection unit 7. The detection unit 7 is used to detect the amount of medium.

[0040] The locking module 5 is arranged on the transmitter 3 . After a certain amount of medium is introduced into the transmitter 3 , the locking module 5 locks the detection medium in the transmitter 3 .

[0041] In this embodiment, the liquid supply module and the detection module are set up to fill the selected transmitter 3 with a corresponding amount of medium. After filling, the transmitter 3 is detected to detect the amount of medium inside it and compare it with the preset filling amount, so as to quickly obtain the detection result and improve the detection efficiency.

[0042] In an exemplary embodiment, the present invention also includes a vacuum unit 4, which is connected to the transmitter 3. The vacuum unit 4 is used to perform vacuum treatment on the transmitter 3. A first valve 9 is provided between the vacuum unit 4 and the transmitter 3. When the first valve 9 is opened, the vacuum unit 4 performs vacuum treatment on the transmitter 3.

[0043] In this embodiment, the transmitter 3 can be evacuated by the vacuum unit 4 so that the inside of the transmitter 3 can maintain a vacuum state, so as to facilitate the subsequent measurement of the amount of medium inside the transmitter 3. The first valve 9 is set. When the first valve 9 is opened, the vacuum unit 4 works and the inside of the transmitter 3 is evacuated through the interface between the vacuum unit 4 and the transmitter 3.

[0044] Exemplarily, in this embodiment, the vacuum unit 4 includes a vacuum pump, a vacuum pipe and a vacuum gauge. The vacuum pipe connects the transmitter 3 and the vacuum pump. The first valve 9 is set on the vacuum pipe. When the first valve 9 is opened, the vacuum pump is started synchronously. The vacuum pump evacuates the transmitter 3 and the vacuum gauge detects the vacuum degree. When the requirement is met, the vacuum pump is turned off and the vacuuming is completed.

[0045] It is worth noting that the vacuum unit 4 in this embodiment may also adopt other devices and components capable of evacuating a vacuum, as long as they can evacuate the transmitter 3 .

[0046] In an exemplary embodiment, the liquid supply module includes a medium source 2 and an exchange processing unit 1, the exchange processing unit 1 is connected to the transmitter 3, the medium source 2 is connected to the exchange processing unit 1, and a second valve 10 is provided between the medium source 2 and the exchange processing unit 1. When the second valve 10 is opened, the exchange processing unit 1 fills the transmitter 3 with medium.

[0047] The medium source 2 in this embodiment is used to provide medium to the transmitter 3, and the exchange processing unit 1 processes the medium and then sends it into the channel connected to the transmitter 3, and the medium is introduced into the transmitter 3, and the control is achieved through the second valve 10. When the second valve 10 is opened, the medium in the medium source 2 flows into the transmitter 3. The opening time of the second valve 10 is controlled by the control module to pass the medium amount corresponding to the target transmitter 3.

[0048] In an exemplary embodiment, the control module further includes a control unit 6 , and the first valve 9 and the second valve 10 are both electrically connected to the control unit 6 .

[0049] The control unit 6 in this embodiment can control the opening time and duration of the first valve 9 and the second valve 10. The control unit 6 can realize automatic and refined control without manual operation.

[0050] Exemplarily, the control unit 6 in this embodiment adopts a PLC controller to realize the control of the first valve 9 and the second valve 10, but it is not limited to the PLC controller, and other controllers can also be used to realize the corresponding functions.

[0051] In an exemplary embodiment, a third valve 12 is provided on the exchange processing unit 1, and the third valve 12 is electrically connected to the control unit 6. A reference source 8 is preset in the control unit 6. The detection unit 7 is used to detect the amount of medium inside the transmitter 3. When the amount of medium introduced into the transmitter 3 by the exchange processing unit 1 is the same as the reference source 8, the locking module 5 works to encapsulate the medium in the transmitter 3, the third valve 12 opens, and the excess medium in the liquid supply module flows out from the third valve 12, and the reference source 8 is reset at the same time.

[0052] In this embodiment, through the preset reference source 8, the required amount of medium entering can be determined according to the target transmitter 3, and the amount after the medium is passed into the transmitter 3 is compared with the reference source 8, so as to obtain the result of whether the transmitter 3 is leaking, thereby realizing the detection function.

[0053] It is worth noting that, through the fourth valve 11, after the detection is completed, the medium in the transmitter 3 can flow out through the fourth valve 11 to be collected or recovered. The third valve 12 in this embodiment is also controlled by the controller.

[0054] It should also be noted that in this embodiment, after the medium in the medium source 2 enters the transmitter 3 through the exchange processing unit 1, it is maintained for a period of time, during which time it is constantly compared with the reference source 8 to see if there is a difference, which can improve the accuracy of the detection result.

[0055] In an exemplary embodiment, the locking module 5 is disposed between the transmitter 3 and the exchange processing unit 1 , and the locking module 5 is electrically connected to the control unit 6 .

[0056] In this embodiment, the transmitter 3 is locked by the locking module 5, which can effectively prevent the medium in the transmitter 3 from escaping, thereby ensuring the accuracy of the detection result.

[0057] In an exemplary embodiment, a fourth valve 11 is provided on the exchange processing unit 1 . The fourth valve 11 is electrically connected to the control unit 6 . The fourth valve 11 is used to discharge the medium in the transmitter 3 .

[0058] It is worth noting that the fourth valve 11 in this embodiment is controlled by a controller.

[0065] Compare the actual filling volume with the preset filling volume to obtain the test result;

[0066] Determine whether the transmitter 3 is leaking based on the detection result.

[0067] Exemplarily, judging whether the transmitter 3 is leaking according to the detection result includes:

[0068] If the actual filling volume is less than the preset filling volume, the transmitter 3 is leaking;

[0069] If the actual filling amount is equal to the preset filling amount, the transmitter 3 is not leaking.
