3151智能型双法兰液位变送器选型手册(双语通用)

差压变送器与智能放大板组合,可构成智能远传压力、差压变送器,与符合HART协议的手操器配合,可以相互通讯,进行设定和监控。为了适应不同的安装需求,本系列变送器具有多种形式的远传装置供用户选择,变送器的主体结构与差压相同/3151智能型双法兰液位变送器选型手册(双语通用)
The combination of differential pressure transmitter and intelligent amplifier board can form intelligent remote pressure and differential pressure transmitter, which can communicate with each other, set and monitor in cooperation with HART protocol manual operator. In order to meet different installation requirements, this series of transmitters have many forms of remote transmission devices for users to choose. The main structure of the transmitter is the same as the differential pressure
双法兰液位变送器可避免被测介质直接和变送器的隔离膜片接触,这种测量方法适用于下述几种情况被测介质对变送器敏感元件有强腐蚀作用需要将高温被测介质与变送器离3、被测介质中有固体悬浮物或高粘度介质被测介质易固化或结晶5、更换被测介质需严格净化测量头/3151智能型双法兰液位变送器选型手册(双语通用)
The double flange liquid level transmitter can avoid the direct contact between the measured medium and the isolation diaphragm of the transmitter, This measurement method is applicable to the following situations: the tested medium has strong corrosion on the transmitter sensitive elements, and the high-temperature measured medium needs to be separated from the transmitter; 3. There is solid suspension or high viscosity medium in the measured medium, and the measured medium is easy to solidify or crystallize; 5. The measured medium needs to be replaced, and the measuring head needs to be cleaned strictly
逐台进行模拟“在线运行”考核,保证变送器在极限环境温度、介质温度和工作压力(包括正压或真空)下,稳定而可靠地态型面”远传膜片结构,超载后膜片不会受损:;长期工作后精度不会发生变选用全熔焊和刚性密封结构的灌充系统,根除了漏油现象的发设计新颖的毛细管结合部件,使毛细管得到可靠的保护,在现场使用不易折断种、形式和尺寸多样的远传装置,以及丰富的灌充液种类,可以满足各种不同场合的测量提供各种特殊需要包括高温、高真空、快响应和不等长毛细管(差值≤4.5米)远传差压变送器/3151智能型双法兰液位变送器选型手册(双语通用)
One by one, the simulation "on-line operation" assessment shall be carried out to ensure that the transmitter can stably and reliably transmit the profile "remote diaphragm structure under the limit ambient temperature, medium temperature and working pressure (including positive pressure or vacuum), and the diaphragm will not be damaged after overload:; the filling system with full fusion welding and rigid sealing structure will not be selected after long-term operation, A new capillary combination component is designed to eliminate the oil leakage, so that the capillary can be reliably protected. In the field, the remote transmission device with various types, forms and sizes, which is not easy to break, as well as a variety of filling liquid are used, It can meet all kinds of special needs in different occasions, including high temperature, high vacuum, fast response and unequal length capillary (difference ≤ 4.5m) remote differential pressure transmitter
双法兰液位变送器选型的时候尤其要注意一个很重要的因素,就是差压式液位变送器,它是安装在液体容器的底部,通过表压信号来反映液位的高度。在制药、化工行业的液位测量的控制过程中,盛装液 体的容器经常处于有压的情况下,此时常规的静压式液位变送器变不能满足测量要求,由于在传感器电路和结构.上的改进,提高了差压液位测量技术在制药和食品行业的实用价值。/3151智能型双法兰液位变送器选型手册(双语通用)
When selecting the type of double flange liquid level transmitter, we should pay special attention to a very important factor, that is, the differential pressure type liquid level transmitter, which is installed at the bottom of the liquid container and reflects the height of the liquid level through the gauge pressure signal. In the control process of liquid level measurement in pharmaceutical and chemical industries, the container containing liquid is often under pressure. At this time, the conventional static pressure liquid level transmitter cannot meet the measurement requirements. Due to the improvement of sensor circuit and structure, the practical value of differential pressure liquid level measurement technology in pharmaceutical and food industries is improved.
远传差压变送器选型远传变送器是在变送器主体基础上附加远传装置的变型所以其选型工作行:首先确定变送器主体的类型(DP)、测量范围和结构材料,然后按现场的安装要求确传装置类型和丿组成灌充系统的各参数(如灌充液的工作温度、粘度和毛细管的长度)与变送器的性能指标密切相关,因此归入变送器主体选型范畴,不单独列表选择
Selection of remote differential pressure transmitter remote transmitter is a variant of remote transmitter with remote device attached to the transmitter body, so its selection work is as follows: first, determine the type (DP), measurement range and structural material of the transmitter body, Then according to the site installation requirements, confirm that the device type and parameters of the filling system (such as the working temperature, viscosity of the filling liquid and the length of the capillary) are closely related to the performance index of the transmitter. Therefore, they are included in the selection category of the transmitter main body and are not selected in a separate list
