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.

SMW-02-6-S液位开关使用说明
浮球液位开关
浮球液位开关结构主要基于浮力和静磁场原理设计生产的。
带有磁体的浮球(简称浮球)在被测介质中的位置受浮力作用影响:液位的变化导致磁性浮子位置的变化。
浮球中的磁体和传感器(磁簧开关)作用,产生开关信号。
音叉液位开关
音叉液位开关的工作原理是通过安装在基座上的一对压电晶体使音叉在一定共振频率下振动。
当音叉液位开关的音叉与被测介质相接触时,音叉的频率和振幅将改变,音叉液位开关的这些变化由智能电路来进行检测,处理并将之转换为一个开关信号,达到液位报警或控制的目的。
为了让音叉伸到罐内,通常使用法兰或者带螺纹的工艺接头将音叉开关安装到罐体的侧面或者顶部。
电容式液位开关
电容式液位开关的测量原理是:固体物料的物位高低变化导致探头被覆盖区域大小发生变化,从而导致电容值发生变化。
探头与罐壁(导电材料制成)构成一个电容。
探头处于空气中时,测量到的是一个小数值的初始电容值。
当罐体中有物料注入时,电容值将随探头被物料所覆盖区域面积的增加而相应地增大,开关状态发生变化。
上海驰控音叉液位开关ckyc-001说明书一、安装指南(1)安装前说明在安装之前,请再次确认仪表型号是否满足现场的环境要求,如:过程压力、过程温度、介质的化学性能等,确保仪表在安装后能够正常使用。
(2)安装一般地,音叉液位开关可以根据需要安装在任何位置,可以水平安装、也可以垂直安装或倾斜安装。
当被测介质具有粘稠性时,为了减少或避免出现挂料现象,请将仪表垂直安装。
(3)安装方向安装音叉液位开关时,应使叉体面和液体升降或流动保持方向一致,可以避免挂料或由于介质对叉体的阻力而产生的测量误差。
(4)避开入料口如图2,音叉液位开关安装位置的选择时,应避免由于安装在入料口位置而造成的测量误差,甚至损坏仪表。
(5)压力/真空对于过压或欠压的容器或管道,必须保证过程连接处的密封完好性。
安装之前应确认好密封材料是否满足现场过程温度和过程压力的要求。
(6)防潮当仪表安装在户外或有潮气的环境中,如遇到下雨或村在冷凝现象时,雨水和冷凝水便会随之往下流,所以在接入电缆之前,请将电缆线弯曲并朝下引,以防止水或潮气进入仪表,如图3所示。
二、接电(1)安全提示(a)从安全角度考虑,只有在断电的情况下才能进行接线;(b)对于防爆型仪表接线时必须遵循相关防爆的接线要求。
(2)接入电缆音叉液位开关的电缆一般采用横截面为圆形的通用电缆。
电缆横截面直径为5-9mm,否则无法确保电缆入口的密封效果。
如果您需要使用其它规格的电缆,请使用匹配的电缆入口螺栓,并注意更换后电缆入口的密封性能。
(3)接线图接线时,请按照如图4和5所示方式进行安全接线。
(4)接线步骤对于隔爆型仪表,只有当环境中不存在会引爆的气体或粉尘时才允许打开外盖操作。
请按照如下步骤进行操作:(a)打开外壳盖;(b)松开电缆螺纹接头上的锁紧螺母;(c)去掉连接电缆大约10cm的外皮和芯线末端大约1cm的绝缘层;(d)将电缆穿过电缆螺纹接头插入外壳中;(e)用螺丝刀打开接线端子;(f)按照接线图将芯线末端插入接线端子中;(g)用螺丝刀拧紧接线端子;(h)通过轻拉接入的电缆线来检查接线是否牢靠;(i)拧紧电缆螺纹接头的锁紧螺母,扣紧密封环;(j)拧上外壳盖。
