Vibrating string strain gauge is a product of vibrating string elastic beam structure designed by our factory through years of practice. It completely changes the traditional measurement method of using bellows as elastic element, and has the characteristics of high pressure resistance, radial force resistance, secondary sealing, zero point stability, all stainless steel shell, etc. It is suitable for long-term burying in concrete structures of beams, columns, pile foundations, supports, retaining walls, hydraulic structures, linings, piers and footings and their rocks to monitor their stress and strain, and to simultaneously measure the temperature of the burial point, or to choose a thermistor as a temperature measuring element.
