Description

Technical Field

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

[0002] With the continuous development of industrial Internet, Internet of Things and automation, intelligent weighing is increasingly widely used in logistics, sorting and other fields. As an important component for intelligent weighing data perception, the use of sensors on belt scales is usually to install four sensors at the four corners below a belt scale. The sensor and the belt scale are connected through a pressure head assembly. However, in actual application, the pressure head assembly has major problems. The main problem is that after the belt is running, the entire weighing platform vibrates, causing the steel ball in the pressure head assembly under at least one corner of the belt scale to shake greatly, causing the weighing data to jump, which seriously interferes with the stability and accuracy of subsequent data processing and weighing display. For this reason, we proposed a pressure head assembly for the sensor. Utility Model Content
