1.Pressure type level transmitter consists of transmitter, signal amplifier etc . It is used for continuously 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 level height signal into electric signal .The output signal is changed into 4`20mA(2-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. 2.Technical parameter output:4 20mADC accuracy:≤±0.5%F.S supply voltage:12 28v DC range:standard175 4000mbar absolute 1400 4000mbar overpressure:standard6 25bar absolute:10 25bar diaphragm cell:capacitive transmitter with ceramic diaphragm material:diaphragm:ceramic sensor body:SUS304/SUS316L operating temp range: transmitter:-40 125degree amplifier:-25 55degree protection class: transmitter:IP68/submersible amplifier:IP66 intrinsically safe type:ex ia c T3-T6 cable length:3m in standard(option:up to50m)
