1 主要技术参数
⑴ 工作温度:-20℃~80℃;
⑵ 变送器的准确度等级分为:
0.1级,基本误差为±0.1;
0.3级,基本误差为±0.3;
0.5级,基本误差为±0.5(基本误差以量程的百分数表示)。
⑶ 热零点漂移
环境温度偏离参比工作条件时,变送器的零点漂移应不大于0.03%FS/℃。
⑷ 热灵敏度漂移
环境温度偏离参比工作条件时,变送器的满量程漂移应不大于0.03%FS/℃。

3 安装方法
⑴ 选择易于操作、维护的地方进行安装;
⑵ 应尽量远离振动源安装;
⑶ 应尽量远离热源的地方安装;

5 零点,增益调节
零点及增益的调整方法:
压力表在出厂前,已经过标定,无须用户再次调整。若在使用过程中发生零位和满量程偏离,规定每年校检,可以在高一级精度的压力源上重新标定。方法如下:
在无压力的情况下,调整调零Z电位器,使电流输出为4.000mA。加满量程压力,调整增益S电位器,使电流输出为20.000mA。如此反复多次,最终使压力表的零位和满量程调整到标准值。
6 安全使用注意事项
⑴ 搬运与安装变送器时应小心谨慎,避免碰撞而影响电路的性能。
⑵ 变送器进压口内有隔离膜片,切勿人为用异物触碰。
⑶ 变送器外螺纹处一定要注意密封,否则会造成压力不准不稳。
⑷ 安全栅须取得防爆合格证,其安装应按其说明书的要求进行。
⑸ 在产品安装使用中如遇到问题请与我公司联系,在产品发生异常时,请不要擅自打开进行修理,应及时与厂家联系。

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
The given measuring ranges are also available in kg/cm2, kPa and MPa. Special measuring ranges between 0 ... 0.4 and 0 ... 1,600 bar are available on request. Special measuring ranges have a reduced long-term stability and increased temperature errors.
Overpressure limit The overpressure limit is based on the sensor element used. Depending on the selected process connection and sealing, restrictions in overpressure safety can result. A higher overpressure limit will result in a higher temperature error.
