◆概述 GENERAL
壓力式液位傳感器主要由傳感器、信號(hào)放大器等組成。適用于持續(xù)測(cè)量壓載艙、吃水計(jì)以及燃油艙等多種介質(zhì)的液位。安裝在液艙底部的傳感器可及時(shí)感應(yīng)由于液位變化引起的壓力變化，并將壓力變化轉(zhuǎn)換成電信號(hào)，通過(guò)電纜傳送給信號(hào)放大器，輸出4-20MAa(兩線制)直流信號(hào),此型號(hào)可由液位顯示器直接顯示液位的數(shù)值,并可由裝載計(jì)算機(jī)顯示和控制艙柜的液位。
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
