一、產品簡介 Product introduction
FY2088系列擴散硅壓力變送器采用進口壓力傳感器為測量元件,配以的電子電路而組裝成的一次儀表,具有的抗腐蝕性能及高穩定和高精度,并有標準型、耐高溫型、耐腐蝕型及防爆等多種形式，可廣泛用于石油、化工、電力、冶金、制藥、食品等許多工業領域，可適應工業各種場合及介質，是傳統壓力表及傳統壓力變送器的理想升級換代產品，是工業自動化領域理想的壓力測量儀表。
FY2088 series of diffusion silicon pressure transmitter adopts imported pressure sensor as measuring element, An instrument with advanced electronic circuits and the assembled, Excellent corrosion resistance and high stability and high precision, And the standard type, high temperature - resistant, corrosion resistant and explosion-proof forms, Can be widely used in petroleum, chemical, electric power, metallurgy, pharmaceutical, food and many other industrial fields, Can adapt to various industrial environments, Is the traditional pressure gauge and traditional pressure transmitter ideal upgrade product, Pressure measuring instrument in the field of industrial automation is the ideal.

FY2088系列擴散硅壓力變送器是利用流程壓力和大氣壓力分別加在傳感器的兩側，使傳感器的膜片產生很小的位移，膜片上的蕙斯登電橋將壓力轉換成正比的電壓輸出，再經電子線路放大并轉換成標準的直流電流信號輸出。它抗過載和抗沖擊能力強，溫度漂移小，穩定性高，具有很高的測量精度。
FY2088 series of diffusion silicon pressure transmitter is flow pressure and atmospheric pressure are added to both sides of the sensor, The diaphragm of the sensor produces a small displacement, The diaphragm LOH, Wheatstone bridge output voltage is proportional to the pressure switch, Then the electronic circuit is amplified and converted into direct current signal output standard. The anti overload and anti impact ability, small temperature drift, high stability, high measuring accuracy.
