一、产品简介 Product introduction
FY3051HP系列智能高静压差压变送器一种适用于石化和电站高压装置的差压变送器，由于其耐压高达32MPa，并可承受单向过载压力而不被损坏,因此能可靠地用于高压系统的差压测量。过程压力通过两侧或一侧的隔离膜片、灌充液传至δ室的中心测量膜片，中心膜片是一个张紧的弹性元件，它对于作用在其上的两侧压力差产生相应变形位移，其位移与差压成正比，最大位移约100um，这种位移转变为电容极板上形成的差动电容，由电子线路把差动电容转换成二线制的4-20mADC信号，供给PLC及二次仪表。
FY3051HPseries intelligent high static pressure differential pressure transmitter is akind of differential pressure transmitter suitable for petrochemical and powerstation high-pressure devices. Because its withstand voltage is up to 32Mpa,and it can withstand unidirectional overload pressure without damage, it can bereliably used for differential pressure measurement of high-pressure system. theprocess pressure is transmitted to the central measuring diaphragm of the δchamber through two or one isolation diaphragm and filling liquid. The centraldiaphragm is a tensioned elastic element, which produces correspondingdeformation displacement for the pressure difference between the two sidesacting on it, the displacement is proportional to the differential pressure,and the maximum displacement is about 100um. this displacement is convertedinto the differential capacitance formed on the capacitor plate. Thedifferential capacitance is converted into a two-wire 4-20madc signal by theelectronic circuit, which is supplied to PLC and secondary instruments.
FY3051HP系列智能高静压差压变送器除具有远程通讯功能外，还具有内部量程和调零按钮，便于现场重新调整量程和零位、变送器的输出有线性或开方，均可以通过软件实现。此外变送器可以在4~20mA传输信号上叠加一个数字通讯信号进行查询和诊断，在不中断过程输出信号，可在控制室对变送器进行远程查询和重新组态。
FY3051HPseries intelligent high static pressure differential pressure transmitter inaddition to the remote communication function, it also has the internal rangeand zero adjustment button, which is convenient to adjust the range and zeroposition on site. The output of the transmitter has linear or square root,which can be realized by software. in addition, the transmitter can add adigital communication signal on the 4 ~ 20mA transmission signal for query anddiagnosis, and output the signal without interruption. The transmitter can beremotely queried and reconfigured in the control room.
FY3051HP系列智能高静压差压变送器广泛应用于各种工业自控环境，涉及水利水电、铁路交通、智能建筑、生产自控、军工、石化、油井、电力、船舶、机床、管道等众多行业。
FY3051HP seriesintelligent high static pressure differential pressure transmitter is widelyused in various industrial automatic control environments, involving waterconservancy and hydropower, railway transportation, intelligent building,production automatic control, military industry, petrochemical, oil well,electric power, ship, machine tool, pipeline and many other industries.
