A novel solution for measuring pressure non-invasively is presented, offering new perspectives for retrofittable monitoring and optimization applications. The clamp-on sensor is based on measurement of the circumferential deformation of pressurized pipes, using a compliant pre-stressed metal clamp with strain gauges as sensing elements. The design concept of this measurement system is presented, including the underlying functional mechanisms. Its achievable measurement performance and applicability limitations have been derived from long-term validation tests.
