音叉式物位开关说明书

音叉式物位开关说明书

☆产品简介:音叉式物位开关是一种新型的物位开关。

仪表由一个发讯叉体和放大器部分组成,在叉体根部压紧两组压电晶体,一组作为驱动器,驱动叉体产生振动,另一组作为检测器,用以将叉股转换成电压信号。

当叉股受阻时,振动器振幅变小,振动频率改变,继电器输出开关信号。

从而实现物位限位测量。

传感器材质为316不锈钢,可抗轻度腐蚀,用于限位控制器和高/低位报警。

☆工作原理:音叉式物位开关工作原理根据物料对振动中的音叉有无阻力,探知料位是否到达或超过某高度,并发出通断信号。

传感器的音叉以固有的频率振动,当音叉触及液体或其他物料时,其固有的振动频率降低,能量消耗在物料颗粒间的摩擦上,迫使振幅急剧衰减而停振,频率的变化激活液位开关,产生通断信号。

☆典型应用:●自来水、矿泉水●流动性好的固体粉料●可产生气体的液体●纸浆、胶水、染料●柴油等危险场所●废水、泥浆、酸碱溶液●啤酒、啤酒发酵剂、饮料一、拆箱小心的打开包装箱并除去包装箱内的填充物,仔细核对装箱单上的每项条款,包括仪表型号、安装附件、说明书等,若发现有缺货,与装箱单不符或破损现象,请立即与我公司联系。

二、查看说明书该说明书包括仪表的技术参数、安装及调试规范,请仔细阅读说明书中的每一项内容,如对说明书中的内容有不明白的地方,可以打电话或传真的方式与我公司联系。

三、技术参数●供电:24VDC(标准);220V AC(可选)●环境温度:-20℃~70℃●输出方式:SPDT继电器(单刀双掷)●介质温度:-40℃~150℃●工作压力:小于2MPa ●介质密度:最低0.6g/cm3●回差设置:约3mm ●功耗:0.5W●高低位报警:现场可设置为高位或地位报警●电气接口:M20*1.5●过程连接:NPT 1”螺纹安装(标准螺纹)法兰安装(可选)●外壳防护:IP66四、产品特点●适应性强:被测液体不同的电参数、密度对测量均不产生影响。

结垢、搅动、湍流、气泡、振动、中等粘度、高温、高压等恶劣条件对检测也无影响。

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.

This center, available 24 hours a day, will assist you with any needed information or materials.The center will ask for product model and serial numbers, and will provide a Return Material Authorization (RMA) number. The center will also ask for the process material to which the product was last exposed.Rosemount National Response Center representatives will explain the additional information and procedures necessary to return goods exposed to hazardous substance can avoid injury if they are informed of and understand the hazard. If the product being returned was exposed to a hazardous substance as defined by OSHA, a copy of the required Material Safety Data Sheet (MSDS) for each hazardous substance identified must be included with the returned goods.WarrantyEmerson Process Management will replace a faulty or failed 2110 with a new unit provided that the fault or failure is reported either directly or via an accredited representative, within 1 year from the date of supply, and the product has been installed and used in accordance with Emerson Process Management instruction manual 00809-0100-4029.

确保液体处于规定的温度和压力范围之内。
安装时,不得用手抓握叉股或敲击叉股,以免叉体受力变形,甚至损坏内部压电晶体。
安装时,不允许仰装方式,即叉端向上方式。
水平安装时,两个叉股必须处于同一高度,不能一上一下。
仪表安装位置,必须尽量避免物料的直接冲击或飞溅。如无法避免,可以在仪表安装 上方,安装防护罩,防止物料冲击叉体。

☆产品简介:
音叉式物位开关是一种新型的物位开关。

仪表由一个发讯叉体和放大器部分组成,在叉体根部压紧两组压电晶体,一组作为驱动器,驱动叉体产生振动,另一组作为检测器,用以将叉股转换成电压信号。

当叉股受阻时,振动器振幅变小,振动频率改变,继电器输出开关信号。

从而实现物位限位测量。

传感器材质为316不锈钢,可抗轻度腐蚀,用于限位控制器和高/低位报警。

☆工作原理:
音叉式物位开关工作原理根据物料对振动中的音叉有无阻力,探知料位是否到达或超过某高度,并发出通断信号。

传感器的音叉以固有的频率振动,当音叉触及液体或其他物料时,其固有的振动频率降低,能量消耗在物料颗粒间的摩擦上,迫使振幅急剧衰减而停振,频率的变化激活液位开关,产生通断信号。

☆典型应用:
●自来水、矿泉水●流动性好的固体粉料●可产生气体的液体
●纸浆、胶水、染料●柴油等危险场所●废水、泥浆、酸碱溶液●啤酒、啤酒发酵剂、饮料一、拆箱
小心的打开包装箱并除去包装箱内的填充物,仔细核对装箱单上的每项条款,包括仪表型号、安装附件、说明书等,若发现有缺货,与装箱单不符或破损现象,请立即与我公司联系。

二、查看说明书
该说明书包括仪表的技术参数、安装及调试规范,请仔细阅读说明书中的每一项内容,如对说明书中的内容有不明白的地方,可以打电话或传真的方式与我公司联系。

三、技术参数
●供电:24VDC(标准);220V AC(可选)●环境温度:-20℃~70℃
●输出方式:SPDT继电器(单刀双掷)●介质温度:-40℃~150℃
●工作压力:小于2MPa ●介质密度:最低0.6g/cm3
●回差设置:约3mm ●功耗:0.5W
●高低位报警:现场可设置为高位或地位报警●电气接口:M20*1.5
●过程连接:NPT 1”螺纹安装(标准螺纹)法兰安装(可选)●外壳防护:IP66
四、产品特点
●适应性强:
被测液体不同的电参数、密度对测量均不产生影响。

结垢、搅动、湍流、气泡、振动、中等粘度、高温、高压等恶劣条件对检测也无影响。

●不需调校:
由于音叉限位开关的检测不受被测介质电参数及密度的影响,所以无论测量何种液体都不需现场调校。

免于维护:
由于音叉限位开关的检测过程由电子电路完成,无活动部件,所以一经安装投运使用便不需要维护。

五、安装说明
音叉限位开关通常采用侧装(在仓壁侧面安装)方式安装与仓体侧壁对料位高度进行上下限位置的检测;当仓体不便侧面开孔时可采用顶装(在仓的顶部安装)方式安装,位置应选择能避开进料时物料冲击的位置;亦可安装与管道上防止泵的无料运行。

●注意事项:
安装传感器时,将其插入罐体,用扳手卡住传感器螺纹上部的六方形拧紧即可,注意不要用手拧动壳体,因为在拧紧的过程中会造成壳体与探杆间发生转动。

在出厂时壳体内部的电子单元与传感器的连接电缆已接好,用力拧壳会使内部的连接电缆拉断。

安装施工时注意叉体不要受到强烈冲击,以免损坏压电晶体。

仪表传感器应尽量避开物料的冲击,水平安装时,叉体的两个平行叉应取与地面垂直方式(此时叉体方向标记冲上或者冲下),以保证物料能容易地从叉板之间流出。

六、产品调试
(一)检查电源接线:
所有电源接线均接至电子单元顶部的端子板上。

元件位置分布图
直流24V供电交流220V供电
继电器输出继电器输出
(二)高低位报警选择:
高低位报警可在现场由安装在电子单元上的高低位报警选择跳块进行设置。

在右侧时为高位报警,在左侧时为低位报警(出厂时一般设为高位报警,也可以改变输出接线)。

高位报警:当物料淹没传感器中心端时(或仪表出现故障时),发出高位报警信号(跳块位置如图1所示)。

低位报警:当物料低于传感器中心端时(或仪表出现故障时),发出低位报警信号(跳块位置如图2所示)。

图1.高位报警图2.低位报警
(三)继电器的接线
每台仪表带有一组继电器触点(SPDT)单刀双掷,继电器仅作为一个开关,不能直接带动报警器或其他较大功率设备动作。

所有控制信号均由电子单元顶部的端子排输出。

绿灯亮时表明继电器工作正常(未报警,如图3所示),灯灭时继电器处于报警状态(在断电或仪表出现故障时,继电器也处于报警状态,如图4所示)。

图3.高位报警图4.低位报警
打开外壳上盖,内有接线端子、拨动开关、发光二极管LED,灵敏度调节钮。

灵敏度调节钮顺时针旋转,灵敏度降低;逆时针旋转,灵敏度增高。

通常出厂时已标好无需调校,对于高粘度液体介质,一般调低灵敏度。

七、测试
出厂时一般调至高位报警,将音叉式物位开关接上电源,灯亮将其提起后垂直插入水中,插入深度应大于25mm,此时输出指示灯点灭;再将音叉提起离开水面,输出指示灯变亮,说明仪表工作正常。
