Apparatus and method for testing a pressure sensing mat

摘要

A testing apparatus for testing a pressure sensing mat comprises a support plate for arranging thereon a pressure sensing mat to be tested, a pressure source and a pressure chamber, fluidly connected to the pressure source for generating pressure in the pressure chamber. The pressure chamber is partially delimited by a substantially fluid-tight flexible membrane operationally arranged in facing relationship to the support plate. In operation, the flexible membrane transmits pressure generated in the pressure chamber onto the pressure sensing mat when the pressure sensing mat is arranged on the support plate. The apparatus further comprises a diagnostic circuit connectable to the pressure sensing mat for measuring an electrical response of the pressure sensing mat to the pressure transmitted thereon by the membrane.
