Abstract
A service life testing device for a pressure sensor includes a first and a second plates, the first plate including a stage carrying a to-be-tested pressure sensor; a pair of drivers, two ends thereof respectively connected to the first and the second plates; a pair of linear slide mechanisms, disposed between the first and the second plates, and each including a slide rail and a slider moving there along, where a compression spring is disposed along an axial direction of each slide rail; a jig, disposed between the first and the second plates, and facing the to-be-tested pressure sensor; and a processing unit, electrically connected to the drivers and the to-be-tested pressure sensor, and configured to control a moving direction, a moving speed, and a moving stroke of the drivers, to cause the to-be-tested pressure sensor to press against or move away from a surface of the jig.
