9500 Vibrating Wire Piezometer
Introduction
The 9500 vibrating wire water pressure gauge is fixed on both ends of the stainless steel cylinder by a group of vibrating wire sensing elements. A set of electromagnetic coils is used to excite the vibration of the steel string. By measuring the vibration frequency of the steel string, the correction coefficient can be used to calculate the pressure value acting on the sensing element, thereby achieving monitoring of groundwater pressure. This product is mainly used to monitor the groundwater pressure of structures such as water conservancy facilities, basic engineering, retaining walls, dams, embankments, deep excavation bases, tunnels, and landfill sites.
