It is a compact switch with a rugged stainless steel body and forks for use in a wide range of liquid applications. Economical 3/4-in. or 1-in. threaded mounting in pipes or tanks or hygienic mounting for food industry use. Direct load switching suits all supplies or PNP output for direct interface to PLCs. For use in safe area only.Short Fork TechnologyThe natural frequency (~1300Hz) of the fork is chosen to avoid interference from plant vibration which may cause false switching. This also gives short fork length for minimal intrusion into vessel and pipe. Using Short Fork Technology, the Rosemount 2110 isdesigned for use in virtually all liquid applications. Extensive research has maximized the operational effectiveness of the fork design making it suitable for almost all liquids, including coating liquids (avoid bridging of forks), aerated liquids, and slurries.Rosemount 2110 Application and Mounting ExamplesFor most liquids including coating and aerated liquids and slurries, the function is virtually unaffected by flow, turbulence, bubbles, foam, vibration, solid particles, build-up or properties of the liquid.For use in safe area and process temperatures up to 302°F (150°C).Mount in any position in the tank or pipe. Mounting is by 3/4-in. or 1-in. threaded or hygienic fitting.2110c l e a r _r e v .t i fReference Manual00809-0100-4029, Rev AAJuly 2005Rosemount 21101-3Overfill ProtectionSpillage caused by overfilling can be hazardous to people and theenvironment, resulting in lost product, and clean up costs. The 2110 is alimit level switch used to signal overfill at any time.Pump ProtectionShort forks mean minimum intrusion wetside and allow simple low costinstallation at any angle into your pipes or vessels. With the fork projectingonly 2-in. (50 mm) (dependant on connection type), the 2110 can beinstalled in even small diameter pipes. By selecting the option of direct loadswitching electronics, the 2110 is ideal for reliable pump control and can beused to protect against pumps running dry.High and Low Level AlarmMaximum and minimum level detection in tanks containing many differenttypes of liquids are an ideal application for the 2110. The robust 2110operates continuously at temperatures up to 302°F (150°C) and operatingpressure up to 1450 psig (100 barg) making it perfect for use as a high orlow level alarm. It is common practice to fit an independent high level alarmswitch to provide extra back up to the level switch in case of failure.Leak DetectionFlanges, gaskets, seals, corrosive liquids – they all have the potential toleak at the most inconvenient times. Many users site tanks and vesselsabove trays or in containments to prevent any liquids from escaping. Alevel switch can quickly and accurately detect any leakage and therebyeliminating cost.Pump ControlMany processes have batching and header tanks, and there is usually theneed to control a pump to maintain levels between set points. These tanksare often manufactured from thin wall materials and cannot support theweight of heavy instrumentation.Hygienic ApplicationsWith the option of highly polished forks providing a surface finish (Ra)better than 0.8 µm, the 2110 meets the principle design criteria of the moststringent hygienic requirements used in food and beverage, andpharmaceutical applications. Manufactured in stainless steel the 2110 isrobust enough to easily withstand steam cleaning (CIP) routines attemperatures up to 302°F (150°C).Reference Manual00809-0100-4029, Rev AA July 2005Rosemount 21101-4Application Considerations •Ensure liquid is inside the temperature and pressure ranges (see specifications).•Check that the liquid is inside recommended viscosity range 0.2 to 10,000 cP .•Examples of products with too high of viscosity is chocolate syrup, ketchup, peanut butter and bitumen. The switch will still detect these products but the drain time can be very long.•Check that the liquid density is above 37.5 lb/ft 3 (600 kg/m 3).•Examples of products with too low of density is acetone, pentane and hexane. •Check for risk of build-up on the forks.•Avoid situations where drying and coating products may create excessive build-up.•Ensure no risk of bridging the forks.•Examples of products that can create bridging of forks are dense paper slurries and bitumen.•Check if solid content in liquid•Problems may occur if product coats and dries causing caking•As a guideline maximum solid particle diameter in the liquid is 0.2-in. (5 mm)•Extra consideration is needed when dealing with particles bigger than 0.2-in. (5 mm), consult factoryHandling the 2110Figure 1-1. Do not hold the 2110 by forks.2110/2110_19a a , 2110_19a a .e p s1-5Figure 1-2. Do not alter the 2110 in any way.2110/2110_27a a .e p s1-6Rosemount IdentificationFigure 1-3.

If selecting a relay to wire in series with the 2110, the user must ensure that the drop-out voltage of the relay is greater than the voltage which will be generated across the relay coil when 3mA flows through it.NOTE (FOR DIRECT LOAD SWITCHING)DPST = ‘Double Pole, Single Throw’ (on/off) switch - must be fitted for safe disconnection of the power supply. Fit the switch as near to the 2110 as possible. Keep the switch free of obstructions.

2120全能型振动音叉液位开关｜测量原理及安装一、测量原理罗斯蒙特 2120 液位开关（简称“液位开关”）基于短音叉振动技术，适合几乎所有液体应用， 2120 采用音叉的工作原理设计。
使用压电晶体以音叉的固有频率对音叉进行振动。
对于这种频率的变化，可进行连续监控。
振动音叉传感器的频率根据浸入的介质而变化。
液体密度越高则频率越低。
当用于低液位报警用途时，容器或导波管内的液体向下排放流经音叉，引起固有频率的变化，这一变化被电子元件检测，从而切换输出状态。
当 2120 用于高液位报警用途时，容器 / 导波管内的液体上升并与音叉接触，又可切换输出状态。
液位开关配有“心跳式”LED，用于指示其工作状态。
当开关的输出为“OFF （关）”时， LED 闪烁，当输出为“ON （开）”时， LED 恒亮。
二、安装准备工作该液位开关可提供本安或防爆 / 防火型。
还可提供适用于普通场所的液位开关型（针对未分类的安全区域）和卫生型。
带重型法兰和延长型音叉的罗斯蒙特 2120 液位开关（简称“液位开关”）的重量可能超过 18 kg (37 lb)。
搬运、吊装和安装液位开关前需要进行风险评估。
对罗斯蒙特 2120 应轻拿轻放，请采用正确姿势。
如下图：环镜考虑因素：此液位开关设计为在开放式或封闭式储罐以及管道上安装。
它不受天气影响，能够防尘，但必须防止其受到水淹。
确保在储罐或管道外有足够的空间。
需要 30 mm (1.2 in.) 空隙，以便拆卸护盖。
务必安装金属外壳盖，使金属与金属接触，或塑料与塑料接触，从而确保正确密封。
应使用罗斯蒙特 O 形圈。
必须按照国家和当地电气规范将外壳接地。
最有效的接地方法是直接接地来获得最小阻抗。
对于带有 NPT 导管入口的金属外壳，应使用音叉的地线。
三、安装建议*避免安装在储罐进液口附近。
*避免音叉溅上大量液体。
应增加延时以减少意外开关情况。
*避免安装在热源附近。
*确保音叉不与罐壁 / 管壁或配件接触。
罗斯蒙特PH计操作规程一、传感器与分析器之间的接线图二、标定菜单三、准备工具：电导率标液、大活扳手一把、抹布若干、水杯一个四、标定过程：电导率的标定我们采用的标定方法类似于单点标定。
首先我们应该将电导率探头取出用蒸馏水或者新鲜水清洗干净。
要是有杂质粘附或者堵塞在探头的检测缝隙内就要用相应的试剂进行清除（或者用其他办法但是必须确保电极的完好）。
清洗完成后要用吸水纸或者干净的抹布将探头尽量的擦拭干净以免杂质（水或者其他电解质）融入试剂中影响标液的试值从而影响标定结果。
清理完后此时需要标定电导率零点，电导率零点的标定很简单就是将探头置于空气中看电导率会不会归零要是不归零就可以用一下方法进行标定按MENU键→进入主菜单→再选中calibrate→进入标定菜单→再选中标定项conductivty→然后选中in process进入标定状态。
此时界面显示上方为测量值，下面为标定值。
此时在下方Cal 的位置输入0然后按ENTER键即可做完这些这些之后就可以开始标定量程了，将探头放进试剂中，此时最好电极是悬浮于标液中不要让电极碰到容器四壁，标液最好高于电极10mm左右以保证电极完全侵没在标液之中，完成这些就可以进行第的标定了。
按MENU键→进入主菜单→再选中calibrate→进入标定菜单→再选中标定项conductivty→然后选中in process进入标定状态。
此时界面显示上方为测量值，下面为标定值。
然后输入此时标准液的真实值例如：147待测量值稳定后就可以按确认键，在此过程中可以轻微的摇晃探头使得电极与标液充分接触，但是小心不能损坏电极，洒落标液或者使电极暴漏于空气中。
此时如果检测示值与真实值偏差过大并且长时间恢复不过来应检查电导池常数（因为一般情况下一旦投用电导池常数是正确的）。
按MENU键→进入主菜单→再选中calibrate→进入标定菜单→再选中标定项conductivty→按右键选中》在按ENTER进入之后选中resistivity进入看里面的数值是否跟要求的（或者名牌上）的电导池常数一致。
