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.

FG600智能静压液位计
一.概述
FG600智能静压液位计是本公司为适应市场需求,而自行开发和生产的新一代液位测量仪表,该仪表具有性能,安装简单和使用方便的特点,FG600系列有六种型号静压液位计:
FG600-1型为沉入缆式结构;
FG600-2型为沉入杆式结构;
FG600-3型为直装螺纹旋入式结构;
FG600-4型为直装法兰式结构,四者均具隔爆和本安型。
FG600-5和FG600-6接触介质部分材料为PTFE或哈氏合金,适用于强酸、强碱等强腐蚀介质测量,具本安防爆型。FG600-5型为沉入缆式结构;FG600-6型为沉入杆式结构。
二.工作原理
FG600智能静压液位计通过压力传感器实现液位测量。压力传感器探入或接触被测液体,受到一定的静压(P)。此压力(P,MPa)与液体高度(h,m)的关系列为P=10&#1471;³ρ gh。式中ρ为被测液体密度(g/cm³),g为当地的重力和速度(m/s²)。对于一定的被测介质和地点,ρ和g为常数,压力和液位高度成正比。如此,通过压力传感器实现了液位测量。

四.防爆型与防腐型液位计安装使用注意事项
(一) 隔爆型
1. 在爆炸危险区域开启液位变送器外壳时,必须切断仪表电源.
2. 把盖旋紧后务必将盖上的紧定螺纹旋紧.
(二) 本安型
1. 液位计应单独安装,尽量远离大功率设备,以避免电磁感应和静电感应.
2. 本安电路的外部导线应单独布置,不允许与高压电缆一起敷设.
3. 液位计到安全栅的连接导线应尽量缩短,禁止盘卷连接导线的分布电感,分布电容与液位计的等效电感,等效电容分别之和须少于安全栅规定的额定值(例如:当导线截面1mm2时,连接导线的总长度不大于1000米).
4. 为确保本安性能,用户不得随意更换器件,维修有困难应送本公司修理.
5. 变送器线路板上设有电源接线端子(端子下面有“+”“-”标记),接线后,端子的卡口外不得有裸铜线
(三) 防腐型(FG600-5、 FG600-6)
FG600-5、FG600-6防腐型静压液位计电缆接触被测介质的材料系聚四氟乙烯.鉴于该材料比金属材料强度差、硬度低等特点,请用户在运输、拆包装和仪表安装过程中,防止仪表受到碰伤、摔损、冲击和折曲等损坏.另外,使用FG600-5的用户需注意以下几点:
1. 切勿折曲电缆和损伤电缆表面;
2. 电缆和传感器、变送器之间不得拉拔;
3. 传感器外壳材料为PTFE的FG600-5必需加配重(其材料为PTFE或哈氏合金C276),配重安装时请将传感器端部的护罩旋下,然后手持传感器将配重旋入,开始旋入时请注意将螺纹对正.
4. 传感器和配重一起投入介质时,请缓慢设放,切勿猛然掷入.
五.安装方式图
注意:FG600-1、FG600-5的导气电缆不可过分夹紧和折曲过锐,FG600-1、FG600-5的安装方式有螺纹连接、法兰连接和分离式三种,法兰连接采用GB9119。.6-88。标准中DN50和DN100作为常用规格.
FG600-3的安装方式为直装式螺纹连接,其外螺纹为G11/2〞、G2〞、G21/2〞(分别对应于不同的最小静压满量程)。
FG600-4的安装方式为直装式法兰连接,法兰标准采用GB9119.6-88.标准中DN50和DN80作为常用规格。
FG600-2、FG600-6的安装方式为螺纹连接和法兰连接,法兰标准采用GB9119.6-88.标准中DN50、DN80作为FG6001-2常用规格,DN65、DN100作
为L301-6的常用规格。
上述法兰常用规格的主要尺寸如下(单位:mm)
公称通经DN | 法兰外径 | 螺栓孔中 心圆直径 | 螺栓孔直径 | 螺栓 | 密封面 直径 | |
数量 | 螺纹 | |||||
50 | 140 | 110 | 14 | 4 | M12 | 88 |

80 | 190 | 150 | 18 | 4 | M16 | 124 |
100 | 210 | 170 | 18 | 4 | M16 | 144 |
六.关于零点和满度调节的说明
液位计出厂前,已校准零点和满度。现场安装后,若测量传感器的安装位置与实际液位的零位有差异时,可通过变送器内的零点电位器调整来实现一致。
零点调整范围为量程的±5%
满度调整范围为量程的±10%
由于结构条件限制,FG600系列隔爆型液位计的零点和满度不能在现场调节,可通过液位显示仪调节。
负载特性 电气连接
最大负载电阻取决于仪表馈电电压,阴影所 注 :①当有表头显示时
①为正②为负③为表头
标注的区域为本安型负载特性区域 ④为表头负
接线工作完后请注意:
1.务必把盖旋紧,直到两端面重合.对于隔爆型液位计尚需再将盖上的紧定螺钉旋紧.
2.将电缆引入口的螺栓旋入,使密封圈抱紧电缆,确保密封.
七.本安型静压液位计防爆系统连接图
八.传感器配重
在测流动性较大的介质时,为防止传感器剧烈摆动、用户可选用配重,它可起到稳定传感器的作用、标准型配重(直径42mm)用于一般测量方式;沉底式配重可将液位计沉入底部亦可利用“配重连接件”的螺栓将其固定在工艺设施上.
九.电缆卡轮的使用
导气电缆长度超过50米的液位计应在电缆长度的1 / 2处(或略大于1 / 2处)用卡轮卡紧电缆,通过尼龙绳吊下边的电缆和传感器,尼龙绳的另一端固定在井口的适当位置.卡轮的卡紧方式如图所示:电缆在轮沟上绕一圈,其交叉处用不锈钢件通过四个不锈钢螺栓压紧,尼龙绳一端穿过不锈钢件的孔并栓紧,另一端上拉至井口固定,卡轮上方的电缆务必处于松驰状态.
