SUN-T系列无源核子料位计上海沃纳机电科技有限公司1、产品原理 ——————— 第2页2、产品特点 ——————— 第3页3、产品介绍 ——————— 第4页4、电厂运用 ——————— 第8页5、产品安装 ——————— 第10页6、调控系统 ——————— 第11页8、产品比较 ——————— 第12页9、公司简介 ——————— 第13页SUN-T 系列 小型 增强功能 无源核子料位计γ射线， 是指波长 1pm—10 pm 的电磁波 ；x 射线，是指波长在1nm—10 nm 的电磁波。

他们是高能量的光子流、电磁波，都是高能射线。

原子在两种状态下会向外释放射线：1、原子核内激发。

当放射性物质的原子核发生α衰变或β衰变时，原子核处在激发态。

而当原子核由激发态跃迁到基态时，会放出高能光子、释放出γ射线、x 射线。

2、原子核外内层电子激发。

当物质的原子受到外部能量激发时，围绕原子核的内层电子会从低能级轨道跃迁到高能级轨道。

而这样的激态电子运动是不稳定的，当它重新回到低基态时，就会以x 射线形式将能量释放出来。

激发方式有剧烈燃烧、高能光子流、电子流轰击等。

高能射线有很强的穿透力，在穿过物质时，强度减弱与物质的密度相关，符合指数规律。

主要机理是一定能量的射线束中的光子与物质发生光电效应、康普顿效应和电子对效应后损失其能量，从原射线束中消失。

光电效应 康普顿效应 电子对效应强度为I 0的射线穿过厚度为t ，密度为ρ的被测物后，强度减为I ，当I 0和t 一定时，I 与ρ相关。

I = I 0e -tρk其中k 为质量吸收系数有源核子料位计的原理是利用人工处理的137Cs、60Co 等放射性物质作为放射源。

γ射线是由物质衰变时放射出的，放射性强度非常高。

其测量是一种主动测量。

当物料达到放射源所在位置时，射线受到物料阻挡与吸收。

接受器根据射线强度的变化，判断物料是否达到测量位置。

无源核子料位计的原理是一种被动测量仪器，不需要人工放射源，充分利用自然环境中广泛存在的微量天然放射性核素所释放的γ射线、X 射线，以及剧烈燃烧、强光子轰击等激发条件下，所释放的X 射线。

微型料位开关全文共四篇示例，供读者参考第一篇示例：微型料位开关是一种用于检测和监控物料水平的设备，其小巧轻便的设计使其非常适合安装在狭小空间或者对装载有限的设备上。

这种开关通常由功能性部件和外壳组成，通过不同的工作原理来实现物料水平的检测。

它们被广泛应用于各种工业领域，如食品加工、化工、医药等，起到了非常重要的作用。

微型料位开关的种类繁多，主要可以分为浮球式、振动式、电容式等几类。

浮球式料位开关通过浮球的上升和下降来开关触点，当物料水位达到一定高度时，浮球会浮在物料表面，从而使开关触点闭合；而当物料下降到一定程度时，浮球则会沉下来，开关触点则会断开。

这种操作原理简单易懂，且结构稳定，因此在许多行业得到广泛运用。

振动式料位开关则是通过探头上的振动部件来实现物料水位的检测，当物料达到一定高度时，会阻碍振动部件的振动，触发开关动作；反之，在低水位时则不会有阻碍振动的物料存在，保持开关处于关闭状态。

这种类型的料位开关由于设计简洁、敏感度高、不易受外界干扰，因此被广泛应用于粉体、颗粒物料的检测领域。

电容式料位开关通过物料和电容传感器之间的介电常数差异来实现开关触点的动作。

当物料接触到电容传感器时，会改变电容传感器感应的电容值，从而触发开关的动作。

这种类型的料位开关具有精确的检测能力，可以应用于各种不同介电常数的物料，具有较强的通用性和灵活性。

微型料位开关在工业领域有着广泛的应用，可以用于物料的控制、监测和报警。

在食品加工行业，微型料位开关可以用于监测食品的水平，确保生产过程的顺利进行，同时也可以用于检测食品的残留物料，保障产品质量。

在化工行业，微型料位开关可以用于监测化工原料的储存和消耗情况，及时控制生产过程，确保生产安全。

在医药行业，微型料位开关可以用于监测药品的存储情况，精准控制药品的配料比例，保障产品质量。

虽然微型料位开关在工业领域有着广泛应用，但是在选择和安装时仍需注意一些问题。

需要根据物料的特性来选择适合的料位开关类型，确保其可以正确地检测物料水平。

SITRANS LU 01 level monitor uses one Siemens Milltronics ultrasonic transducers (ordered separately) to accurately monitor material levels without material contact.The SITRANS LU 01 transmits electronic pulses to each connected ultrasonic transducer.The transducer converts the electronic pulses to ultrasonic pulses which are emitted from the transducer face in a narrow beam. The SITRANS LU 01 measures the time from the pulse emission, to reception of the reflection (echo) from the material. Using the time measured, the SITRANS LU 01 calculates the distance from the transducer face to the material.The distance calculation depends upon the sound velocity within the vessel. When an Echomax transducer is used, variable air temperatures are automatically compensated.For superior air temperature compensation, a Siemens Milltronics TS-3 temperaturesensor may be used for each vessel. A simple calibration feature compensates forThe SITRANS LU 01 uses Siemens Milltronics patented Sonic Intelligence®echoprocessing. Sonic Intelligence provides high measurement reliability, regardless ofchanging conditions within the vessel monitored. By using ultrasonic echo rangingprinciples with Sonic Intelligence and velocity compensation, the SITRANS LU 01provides outstanding measurement accuracy, usually within 0.25% of range.The distance calculation can be converted to space, material level, material volume, or remaining vessel capacity. The reading chosen (and operating data) for each vessel is displayed on the LCD (liquid crystal display).The relays and mA outputs may be used as preset (or programmed as desired) to activate alarms and/or operate remote monitoring equipment and/or process control equipment.With the addition of a Siemens Milltronics Smartlinx ® protocol specific plug-in communications module, the SITRANS LU 01 is compatible with popular industrial control system standards. Supported protocol include PROFIBUS DP, Allen-Bradley®1 Remote I/O, Modbus® RTU, and DeviceNet TM.Programming can be done locally using the portable programmer keypad, or remotely through optional Dolphin Plus software or SmartLinx.•The programmer transmits the keypad entries via infrared link to the SITRANS LU 01, and can be removed when not in use.•Dolphin Plus allows programming either through the RJ-11 port or hardwired via the RS-232/485 communication port.•SmartLinx provides protocol specific hardware and software for interface with popular industrial communication systems.1.Allen-Bradley is a registered trademark of Rockwell Automation. Modbus is aregistered trademark of Schneider Electric. DeviceNet is a trademark of ODVA(Open DeviceNet Vendor Association).The SITRANS LU 01 is typically used to monitor material level in open or closed vessels but can be used in almost any process which requires a distance measurement (within the system range).Refer to Technical Reference Application Examples on page89 for detailed descriptions of some configuration examples to which the SITRANS LU 01 may be applied.

当射频导纳料位计安装在容器中时就构成了一个电容器，电极的金属棒（测量电极）作为电容的一个极板，容器壁（注：若容器壁为绝缘材料，则应该设置另一个电极，称之为参考电极）作为电容器的另一个极板。

当料位上升到测量电极位置，平常包围在两个电极板间的空气被被测物料取代，由于被测物料与空气的介电常数的差异，导致电容量发生突变，射频导纳料位计通过射频电路检测到这一突变，并转换成开关信号，通过继电器完成开关动作。

一、简介料位计, 是用来测量料仓/容罐/仓储等料位的计量仪表, 并将料位信号（开关量或连续量）转换为电信号（模拟信号或数字信号）传送到PLC/DCS上, 辅助自动化系统控制卸料、加料或停止进料, 保持料仓内料位高度。

料位计又称为料位仪表, 料位传感器, 料位仪, 料位变送器、物位计、物位仪表等。

料位计可测量各种状态的物料, 如液态、浆液状、灰状、粉状、颗粒状、块状等的物料料位, 广泛应用于各个行业。

料位计的分类随着工业自动化水平的提高, 以及在工厂的实践经验中, 料位计种类繁多, 根据不同的分类方式, 有如下种类,1）根据被测对象分为:液位计（测量液体）界面仪（测量液液、固液分界面）物位计（测量固体物料）2）根据测量目的分为:开关量测量（即高低料位报警）连续量测量（实时料位监测）3）根据测量方式及原理分为:接触式: 阻旋式、音叉式、电容式、重锤式、射频导纳式、导波雷达式二、非接触式: 电磁式、超声波式（三维成像）、雷达式、核子式、中子式、射线式、称重式、无源核子、辐射式、激光式三、各种料位计的各种原理及优缺点1.阻旋式料位开关测量原理: 高料位时, 通过电机驱动传动杆末端的桨叶旋转, 当物料覆盖并阻止桨叶旋转时, 输出触点（干接点）报警信号, 同时切断电机电源；低料位时, 桨叶由被覆盖状态到释放, 弹簧将电机拉回工作位置, 输出相反的触点（干接点）报警信号。

适用工况：适用于各种固体物料测量；温度<=800℃, 压力<=10bar, 拽引力<=2.8t, 灵敏度达20g/l, 可要求FDA食品级认证, EHEDG卫生级认证, ATEX、FM/CSA、IEC-Ex、GOST粉尘及气体防爆认证；2.音叉式料位开关测量原理: 高料位时, 通过压电激励探头末端的音叉体产生100~350Hz的振动频率, 当物料覆盖住探头时, 便停止振动, 输出触点（干接点）报警信号；低料位时, 探头由被覆盖状态到释放, 开始振动, 输出相反的触点（干接点）报警信号。
