◆概述 GENERAL
压力式液位传感器主要由传感器、信号放大器等组成。适用于持续测量压载舱、吃水计以及燃油舱等多种介质的液位。安装在液舱底部的传感器可及时感应由于液位变化引起的压力变化，并将压力变化转换成电信号，通过电缆传送给信号放大器，输出4-20MAa(两线制)直流信号,此型号可由液位显示器直接显示液位的数值,并可由装载计算机显示和控制舱柜的液位。
Pressure type level transmitter consists of transmitter,signal amplifier etc.It is user for continously measuring the liquid level of ballast tank,draft ａnd fuel oil tank.The pressure type transmitter in the liquid tank bottom can timely sense the pressure change due to the height change,and change the level height signal into pressure electric signal.The output signal is changed into 4-20mA(two-wire)DC level signal via amplifier.The level signal is transformed to the level indicator in the control panel via safety barrier,or tank level is indicated ａnd controlled by loading computer
