一、产品简介 Product introduction
FY3051AP系列智能绝压变送器可以实现对除气系统，蒸镏干塔、蒸发哭和结晶器等的绝对压力测量，允许在10Mpa下的过压。是专业用于真空测量控制的系列产品，完全解决了真空测量难的问题。作为一种高精度智能型的现场压力参数的检测仪表，用来测量各种介质在液体，气体和蒸汽状态下的压力的参数，并将被测的压力参数转换成4-20mA标准电信号输出，同时采用HART协议，具有与手操器或上位机进行通讯的功能，能适应不同用户的需要。
FY3051APseries intelligent absolute pressure transmitter it can measure the absolute pressure ofdegassing system, distillation tower, evaporation tower and crystallizer, andallow overpressure under 10Mpa. it is a series of professional products forvacuum measurement and control, which completely solves the problem ofdifficult vacuum measurement. as a kind of high-precision intelligent fieldpressure parameter measuring instrument, it is used to measure the pressureparameters of various media in liquid, gas and steam state, and convert themeasured pressure parameters into 4-20mA standard electrical signal output. Atthe same time, it adopts HART protocol, and has the function of communicatingwith the manual operator or upper computer, which can meet the needs of differentusers.
FY3051AP系列智能绝压变送器的绝对压力是指直接作用于容器或物体表面的压力，即物体承受的实际压力，其零点为绝dui真空，符号为PABS(ABS为下标)。包围在地球表面一层很厚的大气层对地球表面或表面物体所造成的压力称为“大气压”，符号为B；用压力表、真空表、U形管等仪器测出来的压力叫“表压力”(又叫相对压力)，“表压力”以大气压力为起点，符号为Pg。
Absolutepressure of FY3051AP series intelligentabsolute pressure transmitter refers tothe pressure directly acting on the surface of the container or object, thatis, the actual pressure on the object. Its zero point is absolute vacuum, andthe symbol is PABS (ABS is subscript). the pressure caused by a thick layer ofatmosphere surrounding the earth's surface on the earth's surface or objects iscalled "atmospheric pressure", with the symbol of B; the pressuremeasured by pressure gauge, vacuum gauge, U-tube and other instruments iscalled "gauge pressure" (also known as relative pressure),"gauge pressure" starts from atmospheric pressure, with the symbol ofPG.
FY3051AP系列智能绝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。
FY3051APseries intelligent absolute pressure transmitter in addition to the remote communicationfunction, it also has the internal range and zero adjustment button, which isconvenient to adjust the range and zero position on site. The output of thetransmitter has linear or square root, which can be realized by software. inaddition, the transmitter can add a digital communication signal on the 4 ~20mA transmission signal for query and diagnosis, and output the signal withoutinterruption. The transmitter can be remotely queried and reconfigured in thecontrol room.
FY3051AP系列智能绝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。
FY3051APseries intelligent absolute pressure transmitter is widely used in various industrialautomatic control environments, involving water conservancy and hydropower,railway transportation, intelligent building, production automatic control,military industry, petrochemical, oil well, electric power, ship, machine tool,pipeline and many other industries.
