[0020] See also Figure 1 The technical solution proposed by the utility model is: a pressure transmitter for a pressure plate in the homogenizer industry, comprising: a flat film elastomer 1 and a fixed rod 5, the left end of the fixed rod 5 is fixedly connected with the flat film elastomer 1, and the fixed connection between the fixed rod 5 and the flat film elastomer 1 is laser welding, and the flat film elastomer 1 is made of martensitic stainless steel material, which is strong and durable to meet the impact of various particles in the homogenizer, and a strain gauge 2 is bonded to the flat film elastomer 1, and the material of the strain gauge 2 is a full bridge piece of polyimide material to meet the environment in which the medium temperature rises due to friction in the homogenizer refining particles, and the right end of the fixed rod 5 is fixedly connected with a protective shell 11, and the fixed connection between the fixed rod 5 and the protective shell 11 is laser welding;

[0021] An integrated circuit 7 is fixedly installed inside the protective housing 11. The setting of the protective housing 11 can protect the integrated circuit 7. A magnetic switch 8 is provided on the integrated circuit 7. An aviation plug 9 is fixedly installed on the right end of the protective housing 11. When the pressure transmitter has a zero drift, the pressure can be reset to zero by using a magnet close to the position of the magnetic switch 8.

[0022] A paint bubble wire 6 is fixedly connected to the strain gauge 2, and the other end of the paint bubble wire 6 is fixedly connected to the integrated circuit 7 to form a pressure measurement body. The paint bubble wire 6 is welded to the strain gauge 2 and the integrated circuit 7 at both ends, respectively, to avoid the paint bubble wire 6 falling off from the integrated circuit 7 and the strain gauge 2, resulting in the inability to perform detection, thereby improving the service life of the pressure transmitter. The paint bubble wire 6 is wrapped by the pectin 12 filled inside the pressure transmitter, so that the paint bubble wire 6 is fixed in the pressure transmitter, further avoiding the risk of the end of the paint bubble wire 6 falling off from the integrated circuit 7 and the strain gauge 2.

[0023] The paint bubble wire 6 passes through the interior of the fixing rod 5, and the integrated circuit 7 is connected to the aviation plug 9 through a silicone wire and outputs a 4-20mA signal. The paint bubble wire 6 is routed from the interior of the fixing rod 5, so that the paint bubble wire 6 can be protected by the fixing rod 5 to avoid the problem of exposure of the paint bubble wire 6.

[0024] A movable pressure plate 4 is sleeved on the fixing rod 5, and four mounting holes are opened on the movable pressure plate 4. The movable pressure plate 4 and the mounting holes can be conveniently fixed with mounting screws. The movable pressure plate 4 can be replaced with different sizes to meet the flexibility of the site. With the traditional threaded structure, the user must drill holes according to the thread size.

[0025] A flat sealing gasket 3 is bonded to the fixing rod 5, and the flat sealing gasket 3 is annular. A counter-edge structure 13 is provided on the outer wall of the fixing rod 5. The setting of the flat sealing gasket 3 can improve the sealing performance of the transmitter. When the pressure transmitter needs to be disassembled, the screws of the movable pressure plate 4 are loosened, and the pressure transmitter can be loosened through the counter-edge structure 13, which facilitates the disassembly of the pressure transmitter.

[0026] An annular groove is provided on the outer wall of the left end of the fixing rod 5, and a high-pressure O-ring 10 is sleeved inside the annular groove. The high-pressure O-ring 10 and the flat sealing gasket 3 cooperate with each other to achieve a double sealing effect, thereby ensuring a more reliable seal under high pressure. By providing an annular groove on the fixing rod 5, the high-pressure O-ring 10 can be conveniently sleeved on the fixing rod 5, thereby limiting the high-pressure O-ring 10 and avoiding the problem of left and right translation of the high-pressure O-ring 10, thereby achieving better sealing.

[0027] The flat film elastomer 1, the fixing rod 5 and the protective shell 11 are filled with fruit gel 12. Since the homogenizer vibrates greatly, the fruit gel 12 filled inside the pressure transmitter can play a shock-absorbing role to prevent signal instability caused by vibration. In addition to protecting the integrated circuit 7, the protective shell 11 also protects the connecting wires between the integrated circuit 7 and the aviation plug 9.

[0028] When the pressure transmitter has zero drift, the pressure can be reset to zero by using a magnet close to the position of the magnetic switch 8. The arrangement of the side structure 13 and the movable pressure plate 4 facilitates the installation and removal of the pressure transmitter. Filling the interior of the pressure transmitter with fruit gel 12 can achieve a shock-absorbing effect, thereby avoiding the problem of unstable signals caused by large vibrations of the homogenizer. The pressure transmitter can be used for remote observation and control and for zeroing on site. The double-layer sealing structure of the flat sealing gasket 3 and the high-pressure O-ring 10 ensures that the sealing is more reliable at high pressure and that the installation is more convenient and compact. The present invention is easy to install and disassemble, can output a 4-20mA analog signal, and is applied to remote observation and control.

[0029] The utility model provides a pressure transmitter for a pressure plate in the homogenizer industry. There are many methods and ways to implement the technical solution. The above is only a preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications should also be regarded as the protection scope of the utility model. All components not specified in this embodiment can be implemented by existing technologies.
