摘要

The device (10) has a pressure sensor (200) integrated to a case (100), and a liquid crystal display screen (300) placed in the sensor for displaying a value representative of the pressure measured by the sensor. A resin (130) fills an interior volume of the case. A transparent cover (120) of the case, the display screen and the sensor are situated in a parallel plane. The case includes a connection insert (500) fixed to the sensor by welding.
