摘要：
A method for measuring a nip pressure and/or a pressure profile is provided, wherein a nip-forming roll is fitted with a pressure sensor under a coating layer which is protective and functions as a spring on top of the sensor, and the nip pressure delivers to the bottom surface of the coating a deformation proportional to the nip pressure and the deformation compresses the sensor, which responds to the deformation by generating an electric signal.
