1 主要技術參數
⑴ 工作溫度:-20℃~80℃;
⑵ 變送器的準確度等級分為:
0.1級,基本誤差為±0.1;
0.3級,基本誤差為±0.3;
0.5級,基本誤差為±0.5(基本誤差以量程的百分數表示)。
⑶ 熱零點漂移
環境溫度偏離參比工作條件時,變送器的零點漂移應不大于0.03%FS/℃。
⑷ 熱靈敏度漂移
環境溫度偏離參比工作條件時,變送器的滿量程漂移應不大于0.03%FS/℃。
⑸ 絕緣電阻
在參比工作條件下,變送器各端子對地之間的絕緣電阻不得低于50MΩ/250V。

3 安裝方法
⑴ 選擇易于操作、維護的地方進行安裝;
⑵ 應盡量遠離振動源安裝;
⑶ 應盡量遠離熱源的地方安裝;
⑷ 直接安裝在管道或設備上,安裝時用扳手夾緊在變送器六方處。

5 零點,增益調節
零點及增益的調整方法:
壓力表在出廠前,已經過標定,無須用戶再次調整。若在使用過程中發生零位和滿量程偏離,規定每年校檢,可以在高一級精度的壓力源上重新標定。方法如下:
在無壓力的情況下,調整調零Z電位器,使電流輸出為4.000mA。加滿量程壓力,調整增益S電位器,使電流輸出為20.000mA。如此反復多次,最終使壓力表的零位和滿量程調整到標準值。
6 安全使用注意事項
⑴ 搬運與安裝變送器時應小心謹慎,避免碰撞而影響電路的性能。
⑵ 變送器進壓口內有隔離膜片,切勿人為用異物觸碰。
⑶ 變送器外螺紋處一定要注意密封,否則會造成壓力不準不穩。
⑷ 安全柵須取得防爆合格證,其安裝應按其說明書的要求進行。
⑸ 在產品安裝使用中如遇到問題請與我公司聯系,在產品發生異常時,請不要擅自打開進行修理,應及時與廠家聯系。

Description The model S-20 pressure transmitter for general industrial applications is the ideal solution for customers with demanding measuring requirements. It features a very good accuracy, a robust design and an exceptional number of variants, meaning it can be suited to the widest range of applications.
Versatile The model S-20 offers continuous measuring ranges between 0 ... 0.4 and 0 ... 1,600 bar in all the major units. These measuring ranges can be combined in almost any way with all the standard industry output signals, the most common international process connections and a wide number of electrical connections. Furthermore, it offers numerous options, such as different accuracy classes, extended temperature ranges and customer-specific pin assignments.
High quality The robust design turns the model S-20 into a very high quality product, which even the most adverse environmental conditions cannot affect. Whether with the lowest temperatures when used outdoors, with extreme shock and vibration in machine building or with aggressive media in the chemical industry, this transmitter can meet all requirements.
Availability All variants described in this data sheet are available on very short lead times. For particularly urgent demands, there is a sizeable stock available.
Measuring ranges
