Problems solved by technology

[0003] Pressure transmitters on the market are usually composed of pressure sensors, circuit boards, bases, housings, electrical connectors, and external connectors. The electrical components are loaded into the base and housing, and solidified by potting, welding, and threading. Fix it by other means, and complete the electrical connection by welding wires or welding electrical connectors. This kind of pressure transmitter has many parts and complex structure, and requires manual labor to complete a series of processes such as production, calibration, testing, and assembly. complex and low quality

At the same time, due to the application characteristics of pressure transmitters, the diversity of customer requirements is high, the degree of customization is high, and the diversity of structures is also large, because it is difficult to realize automatic production

However, as society develops towards intelligence and automation, the demand for pressure transmitters will increase. The current production mode of manual assembly cannot meet the requirements. Automatic production of pressure transmitters is already imminent, but the current common This structure is unsatisfactory and not suitable for mechanical automatic production such as mechanical identification, mechanical picking and assembly
