This model adopted new technique is suitable for many kinds of liquid medium. The LED control system put the electric signal together with the digital display. Also, it can set the zero calibration, full scale value, dots and damping time. Suitable applications include food, pharmaceutical, petrochemical, metallurgical, water-supplying automatically and so on. 工作原理 抗腐蝕的陶瓷壓力傳感器沒有液體的傳遞,壓力直接作用在陶瓷膜片的正面,使膜片產生微小的形變。厚膜電阻印刷在陶瓷膜片的背面,連接成一個惠斯通電橋(閉橋)。由于壓敏電阻的壓阻效應,使電橋產生一個與壓力、激勵電壓成正比的的高度線性電壓信號。標準的信號根據壓力量程的不同標定為 2.0/3.0/3.3mV/V,可以和 應變式傳感器相兼容。通過激光標定,傳感器具有很高的溫度穩定性和時間穩定性,受壓后惠斯登電橋橋臂阻值的變化使電橋失去平衡產生了一個與壓力成正比的電壓輸出信號,經過差分歸一放大器輸出放大后,再經過電壓電流的轉換,變換成4~20mA 的標準電流信號輸出,并可經數顯表頭直接顯示在線壓力值。 Working Principle No liquid transport, the pressure effect the face of the ceramic diaphragm to lead a small distortion. Thick film resistance was printed in the back of the diaphragm to form a Wheatstone bridge. And a voltage signal in high-level linearity comes out. The standard signals were signed by 2.0/3.0/3.3mV/V which is compatible with the transmitter. After some inside transform, it comes out as the current of 4~20mA and displayed by the transmitter.

Suggest the supply Us to be 24V. The connected gauge should be RL=250Ω。If you choose other date for Us and RL,the RL can not exceed RL= Vs-12/0.02 . Use wires to seal the holes on the sides of the transmitter or install the signal wire to the holes and fix by tight nut. The hole without used should be sealed. 出廠前壓力變送器已按訂貨要求調試合格,用戶無需再做調整。長時間使用后如需重新標定,可分別調整 “調零電位器”和“調量程電位器”。壓力量程的下限值對應于4mA,上限值對應20mA. ( Z- 調零電位器 S-調量程電位器) The transmitter has been debugged as the customer’s request, no need to debug again. After long time of using, if needed, it can be debugged by adjust“ Zero electric device” and“ Range electric device”. The down limit of the range should be corresponding with 4mA,and up limit will be with 20mA. ( Z- Zero electric device S- Range electric device) 安裝注意事項 1. 直接安裝在測量點上(任意角度)。 2. 盡量安裝在溫度梯度與溫度波動小的測壓點上,同時避免強振動和沖擊。 3. 室外安裝時,盡可能放置于保護盒內,避免陽光直射和雨淋,以保持變送器性能穩定和延長使用壽命。 4. 測量蒸汽或其它高溫介質時,注意不要使變送器的工作溫度超限。必要時請安裝散熱裝置或其它冷卻裝置連接。 5. 安裝時應在變送器和介質之間加裝壓力截止閥,以便檢修和防止取壓口堵塞而影響測量。在壓力波動范圍大的場合還應加裝阻尼器或壓力緩沖裝置。 Installation notes 1. Direct install to the measuring point(any angles). 2. It is better to be with less temperature fluctuation and avoid the strong vibration. 3. If it is needed to install outside of the house, it is better to put it into a protect case to avoid sun and rain. 4. While measuring the high temperature mediums, please do not exceed the temperature limitation. If necessary, fit it with cooling devices. 5. Add pressure cut-off valve between the transmitter and the medium and add the dampers if the pressure changes a lot. 產品詳細資料請點擊:S.YS4 小巧型數顯壓力變送器.pdf 變送器、壓力變送器、小巧型數顯壓力變送器YS4
