Description

Technical Field

[0001] The present application relates to the technical field of transmitters, and in particular to a remote liquid level differential pressure transmitter. Background Art

[0002] Transmitters are developed from sensors. Any sensor that can output standard signals is called a transmitter. Standard signals refer to signals whose form and quantity range of physical quantities conform to international standards. DC signals are not affected by the inductance, capacitance and load properties of the line, and there is no phase shift problem.

[0003] When a common transmitter is connected to a capillary, the capillary is usually plugged into the transmitter. This may become loose due to repeated plugging, or the converter may be accidentally knocked off, affecting efficiency. At the same time, since the capillary is long, it is easy to get tangled and knotted after long-term use, causing damage to the capillary. Utility Model Content

[0010] Furthermore, installing a scraper can clean the mirror surface of the device body to prevent impurities from adhering to the mirror surface of the device body and affecting its use.

[0011] Through the above solution, magnets are installed on the backs of the two fixing frames, and the two magnets are symmetrical.

[0012] Furthermore, by installing magnets, the fixing frame can be secured when the device body is in use, thereby improving the convenience of the user.

[0013] Through the above solution, the two clockwork springs are both in a reset state, and the two reset springs are both in a stretched state.

[0014] Furthermore, installing the clockwork spring can recycle the capillary tube through the elastic deformation force of the clockwork spring, so that the capillary tube can be evenly rolled up in the fixed frame.

[0020] Furthermore, the fixing frame is made of plastic material, which can reduce the weight of the fixing frame and avoid affecting the measurement results.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] The remote transmission type liquid level differential pressure transmitter can limit the capillary tube by installing a swinging piece, so that the capillary tube can be stably plugged into the extension tube, avoiding looseness between the capillary tube and the extension tube and affecting the use of the device body.

[0034] A remote level differential pressure transmitter in the present embodiment can limit the capillary by installing a swinging piece, so that the capillary can be stably plugged into the extension tube, avoiding looseness between the capillary and the extension tube and affecting the use of the device body.
