The CZJ type magnetostrictive static level is a high-precision measuring instrument used to measure the changes in relative elevation. The liquid level height is accurately calculated by measuring the distance from the electronic chamber's transmitting device to the float. The settlement monitoring system composed of magnetostrictive static level gauges utilizes the principle of communicating vessels to calculate the settlement amount based on the changes in the liquid levels of the equipment at the reference point and the observation point. It is mainly applicable to long-term, automated and high-frequency vertical displacement monitoring in geotechnical and structural safety engineering
