Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and more specifically, to a dual-row needle-type temperature and pressure sensor. Background Technology

[0002] A dual-row needle-type temperature and pressure sensor is a sensor that integrates temperature and pressure measurement functions. It typically contains two independent sensing elements, one for measuring temperature and the other for measuring pressure. This design allows the sensor to provide data on two different physical parameters simultaneously. The dual-row needle sensor design uses needle-shaped sensing elements to enable accurate measurements in confined spaces or with specific materials. Applications of this sensor may include industrial process control, environmental monitoring, medical devices, and scientific research.

[0003] In existing technologies, temperature and pressure sensors have different outputs from their external connectors, requiring different connectors to be replaced, which can easily cause interface confusion during production testing and use. Therefore, we have made an improvement by proposing a dual-row needle-type temperature and pressure sensor. Utility Model Content
