Description

Technical Field

[0001] The utility model relates to the technical field of pressure transmitters, and more specifically to a pressure transmitter capable of preventing pressure shock. Background Art

[0002] A pressure transmitter is a device used to measure, monitor and convert pressure signals. It converts pressure signals into standard electrical signals (such as voltage or current signals) for easy transmission, processing and control. Pressure transmitters are commonly used in industrial automation, process control, mechanical equipment monitoring and other fields, and are commonly found in factories, chemical plants, power plants, the oil industry and other places.

[0003] The working principle of the pressure transmitter is usually based on the pressure sensing element. When subjected to pressure, the sensing element will produce corresponding displacement or deformation, thereby generating an electrical signal. This electrical signal is processed by the conversion circuit and output, which can be a standard analog signal or digital signal, which is used to connect to monitoring systems, PLC controllers, data acquisition devices and other equipment to achieve pressure monitoring and control.

[0004] Pressure transmitters are usually installed in industrial sites or on mechanical equipment. These environments may be subject to the risk of external impact or collision. Since the pressure transmitter itself has too many electronic components, the existing pressure transmitter housing will be subject to external impact, which will cause the internal electronic components to vibrate, thereby causing the internal electronic components to malfunction and affecting their service life.
