SF-P671S4 介绍 Introduction

SF-P671S4由高性能扩散硅压阻式压力传感器作为测量元件,把与液位深度成正比的液体静压力准确测量出来,内部的专用集成电路将传感器毫伏信号转换成标准(电流或电压)信号输出,建立起输出信号与液体深度的线性对应关系,实现对液体深度的测量。产品精度高、体积小。适用于石油、化工、电厂、城市供水、水文勘探领域的液位测量与控制。

SF-P671S4 uses a high-performance diffused silicon piezoresistive pressure sensor as the measuring element to accurately measure the hydrostatic pressure of the liquid proportional to the depth of the liquid level. The dedicat-ed integrated circuit inside converts the sensor's millivolt signal into a standard(current or voltage) signal output, establishing a linear correspondence between the output signal and the depth of the liquid, and achieving measure-ment of the depth of the liquid. The product has high precision and small size.Suitable for liquid level measurement and control in the fields of petroleum,chemical, power plants, urban water supply, and hydrological exploration.
