Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensors, in particular to a pressure-resistant pressure sensor. Background Art

[0002] A pressure sensor is a device or apparatus that senses pressure signals and converts them into a usable electrical output signal according to specific rules. Pressure sensors typically consist of a pressure-sensitive element and a signal processing unit. Depending on the test pressure type, pressure sensors can be categorized as gauge pressure sensors, differential pressure sensors, and absolute pressure sensors.

[0003] Pressure sensors installed on pipelines are relatively common. This type of pressure sensor can monitor the negative pressure in the pipeline cavity in real time. However, when the pressure exceeds the load of the pressure sensor used, it will cause cracks or even explosions on the surface of the device, posing a serious threat to the personal safety of workers and nearby equipment.
