In the common condition, the displacement is less than 0.025mm and the electron wires can get the information of the displacement and transform it to be a standard industry measuring digital. Because the distance between the film and the ceramic body only is 0.1mm, the biggest displacement for the over pressure is 0.1mm. And the transmitter has the ability to resist the strong concussion and over loading. 技術參數 技術指標 使用對象: 液體、氣體或蒸汽 測量范圍: 表 壓：0～5KPa～6MPa; 負    壓：-0.1MPa～2MPa 輸    出: 4～20mADC 電    源: 12～30VDC 負載特性: 4～20mADC 二線制負載R ≤50(V-12) 溫度范圍: 環(huán)境溫度 -20～+70℃ ; 標準介質溫度 -20～+80℃ 外殼防護: 優(yōu)于IP65 防爆類型: 本安型ia Ⅱ CT5(應外配安全柵) Technique Index Technique figures Mediums: Liquid, gas and stream Ranges: Positive pressure:0～5KPa～6MPa; Negative pressure：-0.1MPa～2MPa Output: 4～20mADC Power supply: 12～30VDC Loading: 4～20mADC two-line loading R ≤ 50(V-12) Temperature: Environment -20～+70℃ ; Standard Medium -20～+80℃ Case protection: Better than IP65 Explode-proof:Essential safety iaⅡCT5(Add safe bar outside)   性能指標 綜合: 等級：0.1%、0.25% 、0.5% 溫    漂：± 0.15%F.S/10℃ 穩(wěn) 定 性：優(yōu)于± 0.2% F.S/ 年 穩(wěn) 定 性：優(yōu)于± 0.1%BFSL/ 年 溫度影響：在-20～+70℃范圍內，變化量小于± 0.18%/10℃ 振動影響：在任何方向上振動頻率為20-200H時,變化量小于±0.02%BFSL/年 沖擊影響：任何方向100G沖擊11ms后，變化量小于± 0.02% BFSL 負載影響：只要輸入變送器的端子電壓高于12V，就無負載影響。 位置影響：安裝位置不影響零點 Capability figures Accuracy: Accuracy class: 0.1%、0.25%、0.5% Temperature drift: ± 0.15%F.S/10℃ Stability: Better than ± 0.2% F.S/Year Stability: Better than ± 0.1%BFSL/year Temperature effects: In the scope of -20～+70℃, the change is less than ± 0.18% / 10℃ Vibration effects: Under the vibration frequency of 20-200Hz，the change is less than ±0.02% BFSL/year Concussion effects: After the concussion of 100G for 11ms,the change will be less than ± 0.02% BFSL Loading effects: Make sure the end voltage higher than 12V，there will be on loading effects Position effects: Installing place can not effect the zero point. 結構指標 結構材料：膜片：氧化鋁陶瓷 外    殼：低銅鑄鋁 接觸介質材料：SUS304;（或SUS316及SUS316L可選） 過程連接：標準提供M20×1.5外螺紋 (或者其它約定要求) 電氣連接：可根據需要從任何一個出口引出，建議使用φ10工業(yè)電纜作為引線，以便密封，引出接頭可選用通用電纜接頭PG16或M20× 1.5，不引線一端用端蓋封住。 Structure figures Material: Film: Alumina ceramic Case: Low copper casing aluminum Wetted parts: SUS304；（or SUS316 and SUS316l foroptions） Process Connection: Standard M20×1.5 male thread(or other special requests) Electric connection: It is better to choose φ10 industry wire connect from any exit.

五、系統(tǒng)連接及調試 變送器在測量系統(tǒng)中的連接見圖3。建議電源電壓Us 選用24V.DC。 二次儀表中采樣電阻（負載電阻）RL 的阻值選用250 Ω。如果Us 和RL 選用別的數值，那么RL= Vs-12/ 0.02 值 不能超過由公式計算得到的數值。 變送器頂部兩側面的連接孔用電纜密封或信號線裝配，信號電纜通過緊固螺母鎖緊，不用的連接口必須密封。 五、Connection and debugging See the chart as follow. 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 exceedRL= 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. 如果使用的是本質安全防爆儀表，必須與安全柵配套使用，組成本安防爆系統(tǒng)。 If it is the essential safety pressure gauge, it is necessary to fit with the safe bar to form the essential safety system as following:   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4mA，上限值對應20mA. 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. 六、安 裝 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場合，同時避免強振動和沖擊。 3. 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。 4. 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。 六、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. While measuring the high temperature mediums, please do not exceed the temperature limitation. If necessary, fit it with cooling devices. 4. 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：陶瓷電容型壓力變送器2088.pdf 變送器、壓力變送器、陶瓷電容型壓力變送器2088   本公司經營陶瓷電容型壓力變送器2088，質量保證，歡迎咨詢洽談。
