HCS301利用高安全性KeeLoQ滚动码技术及小封装，低功耗等特点完美的解决了RKE系统的需求。
28位非线性加密算法的序列号和6位状态码组成32位滚动码从而构成66位发射码，编码的长度排除了码扫描的威胁；滚动码的唯一性让编码捕获和再发送（被捕获后再发送）变得毫无用处。
加非常安全。
使用便捷的串口就可以对其数据进行配置，加密密钥和序列号是可写不可读的，也就是说试图获取密钥完全是徒劳。
宽电压范围和4输入口使得设计者可以自由的开发多达15种功能的应用，仅需的组件就是按键和RF电路。
HCS301管脚和模块框图3.系统概述：关键术语：制造商代码——一个64位密令，对每个制造商来说是独一无二的，用来为每个发射机（编码器）提供加密密钥加密密钥——在生产过程中烧录到编码器EEPROM的独一无二的64位密钥，控制着加密算法3.1学习HCS系列产品有好几种便于解码器学习的策略。
接下来做个举例，必需提醒大家这些学习策略有些存在第三方专利权。
HCS301是专门为无钥匙进入系统、车辆安全、自动车库等设计的滚动码编码器，这意味这对这些系统来说它是既便宜又安全的。

• 以成像中起的作用分：
– 发射线圈 – 接收线圈
• 发射线圈、接收线圈共用：
– 体线圈 – 头线圈 – 四肢线圈
• 表面线圈仅用于接收
四. 系统调节
• 进入磁体孔腔的物体影响磁场均匀性分布， 同时使线圈的填充系数发生变化，影响线 圈的阻抗特性和品质因数，每次检查病人 前需要进行校准。
2 涡流
• 根据楞次定律，变化的磁场在周围导电材料 中感应随时间变化的电流——涡流。 • 涡流本身又产生随时间变化的磁场，消弱梯 度场，破坏了梯度场就破坏了编码。 • 涡流补偿
– 利用RC元件使电流脉冲预畸变 – 预先补偿梯度的驱动电流 – 有源梯度屏蔽

1 励磁过程 A. 冷却磁体：主磁体线圈处于超导状 态； B. 线圈加载：注入电流 2 退磁
3.失超( Quench
)
• 超导线圈的部分不再是超导状态，线圈储存 的能量部分变成热能散出； • 热能使得线圈的其他部分加热继而失去超导 状态产生更过的热量，恶性循环直至遍及整 个磁体发生失超。 • 失超原因： – 磁通跳跃（Flux jump）~释放能量 – 摩擦生热（Friction resulting heat）~线圈 的微小运动
2.有源匀场（Actively shimming） • 一系列载流绕组排列在磁体孔径的柱形管上， 每个绕组产生的校正磁场与球形谐波展开式 的一个系数近似，设计这些绕组时必须避免 它们与磁体和梯度线圈的相互影响； • 线圈中的电流在系统安装期间确定并保持不 变，直到有工程师进行再匀场时才改变； • 有源匀场使用的线圈绕组有三类：超导匀场 线圈、常导匀场线圈和梯度线圈

Please read this user’s manual carefully and thoroughly before using the instrument.The HHM301 enables any clamp meter or multimeter to enclose a thick or hard- to-reach conductor, bundle of conductors, or busbar while increasing its AC current measurement range to up to 3000 Amperes.The product has three components: a flexible probe, a current-to-voltage converter, and a pair of banana plug output leads. When formed into a loop, the probe is called a Rogowski coil. A Rogowski coil is a helical coil of wire inside a shield that is designed to be placed around a straight conductor, a bundle of conductors, or a copper busbar that typically carries large currents (>10A). The voltage induced in a Rogowski coil is proportional to the rate of change (derivative) of current in the straight conductor. In the HHM301, the integrator circuit needed to change the output of the Rogowski coil to a voltage signal proportional to current is located inside the current-to-voltage converter.2The converter allows the electrician to choose the HHM301’s full-scale current’s range and therefore its current-to-voltage conversion factor. The rotary switch on the converter has three positions: 30A, 300A and 3000A. With the switch in the 30A position, the unit converts current to voltage at a ratio of 100mV/A and outputs the result to the banana plug output leads. The leads are designed to be plugged into a multimeter or clamp meter operating in AC voltage measurement mode. The electrician can then use a simple formula to convert the meter’s voltage reading back to a current measurement.With the converter switch in the 300A position, the conversion factor changeto 10mV/A; in the 3000A position, the conversion factor is 1mV/A. The three ranges offer the electrician three options for measuring very large currents each with a unique combination of range and resolution.The converter is powered by 2 “AAA” batteries, which are supplied with the instrument.KEY FEATURES• Three full-scale ranges: 0 to 3000A, 0 to 300A, 0 to 30A• 18 in. (458mm) long probe creates 6 in. diameter loop• Measurements accurate within 1% of full-scale range• Probe is safe for CAT III 1000V, CAT IV 600V use, converter is safe forCAT II 1000V, CAT III 600V use• Powered by 2 “AAA”batteries (included)WHAT’S IN THE BOXThe HHM301 (a converter plus a non-detachable probe plus non-detachable 90°banana plug output leads) comes fully assembled in a box along with 2 “AAA” batteries and this user’s manual.3PRODUCTOVERVIEWFig. 1 shows the labels andpositions of the controls,indicators and physicalstructures of the HHM301.Familiarize yourself with thefunctions and meanings ofthese controls, indicators andstructures before moving onto the Setup Instructions andOperating Instructions.Flexible current probe(Rogowski coil)Probe couplingPower/Range rotary switchBanana plug output leadsGreen (power on) LEDRed (low battery) LEDBattery compartmentCurrent-to-voltage converterSAFETY INSTRUCTIONSWarning• Do not operate the HHM301 if the probe, converter or test leads appear to be damaged.• When measuring bare conductors, use appropriate personal protective equipment (PPE) such as rubber gloves and headgear certified for high-voltage work.• Also wear PPE if any circuits in the system remain “live” during themeasurement.• If the magnitude of the current to be measured is unknown, set theconverter’s range switch to the highest (3000A) position to begin testing. 4• Always de-energize the circuit under test before installing the flexibleprobe.• Exercise extreme caution when measuring voltages greater than 60VDC or 30VAC.• Never use the probe on a circuit with voltages higher than CAT III 600V.• Never operate the HHM301 with the converter's battery compartmentdoor open.SETUP INSTRUCTIONSINSTALL BATTERIESWarningBefore changing batteries, move the flexible probe away from any live circuits and set the converter switch to the OFF position.The HHM301’s battery compartment (Fig. 1, Callout 7) is located at the back of the converter. To open the compartment, use a small Phillips-head screwdriver to remove the single screw securing the battery compartment cover. Be careful not to lose the small screw. Put the screw and the cover to the side.Install the two supplied “AAA” batteries in the compartment, using the polarity marks stenciled inside it as a guide. Replace the battery compartment cover and secure it with the Phillips-head screw. OPERATING INSTRUCTIONS1.Power on the HHM301 by turning the converter’s rotary switch from the OFF position to the appropriate Range position: 30A, 300A or 3000A. The green LED on the left side of the front panel (Fig. 1, Callout 5) will illuminate. If the magnitude of the current to be measured is unknown, initially set the switch to the 3000A position. You can switch to a narrower range later to improve your measurement resolution if the magnitude of measured current is low enough to warrant doing so.2. Plug the banana plugs into the test jacks of your multimeter or clamp meter, taking care to observe + (positive/red) and – (negative or common/black) polarity markings.3. On your multimeter or clamp meter, select AC voltage measuremen in Auto Ranging mode, or a full-scale range of 3 to 10V in Manual Ranging mode.54. Pull the end of the probe closest to the mark on the probe coupling (Fig. 1, Callout 2) out of the coupling, enclose the conductor(s) or busbar whose current you wish to measure, and then plug the end of the probe back into the coupling (see figure below).position the conductor(s) as close to the center of the loop as possible, given physical limitations. Measurement accuracy decreases by 1% for each 1 in. of positioning off-center.6. Read the measured voltage on your multimeter or clamp meter. If you are using an Auto Ranging meter, the meter will automatically provide readings with the highest resolution. If you are using Manual Ranging, begin by selecting the meter's widest full-scale AC voltage range. Then try switching to a narrower range to improve your measurement resolution.7. Calculate the measured current from the displayed voltage reading using the following formula:Actual current = Voltage reading ÷ Conversion ratioThe conversion ratio for each of the three HHM301 measurement ranges is stenciled on the converter at the left of the range label. The ratios for the 3000A, 300A and 30A ranges are 1mV/A, 10mV/A, and 100mV/A, respectively.6As an example, consider an application in which your multimeter reads 3VAC with input from the HHM301 operating in the 30A range (see figure below).The conversion factor for the 3A range is 100mV/A. Inserting these values into the formula yields the following result:Actual current = Voltage reading ÷ Conversion ratioX= 3V÷100mV/AActual current =30A7SPECIFICATIONS• Measurement Ranges: 0 to 3000A (full-scale), 0 to 300A, 0 to 30A• Conversion Ratios: 1mV/A in 3000A range; 10mV/A in 300A range; 100mV/A in 30A range• Measurement Accuracy: ±1% of full-scale value• Position Error: ±1% @ 1 in. from conductor; ±2% @ 2 in.; ±3% @ 3 in.• Safety Ratings: CAT III 1000V, CAT IV 600V (probe); CAT II 1000V, CAT III 600V (controller)• Probe Length: 18 in. (458mm); creates 6 in. diameter loop• Probe Diameter: 0.33 in. (8.5mm)• Cable Length (probe to converter): 6 ft. (1.8m)• Bandwidth (-3dB): 10Hz to 10kHz• Output Impedance: 10kΩ, minimum• Operating Temperature: 32° to 122°F (0° to 50°C) @ <80%RH• Dimensions of Converter: 4.7 x 2.8 x 1.0 in. (120 x 70 x 26mm)• Weight (including batteries): 11.4 oz. (325g)• Power Source: (2) “AAA” batteries (included)8OPERATING & MAINTENANCE TIPSWhen the red LED on the right side of the converter’s front panel (Fig. 1, Callout 6) illuminates, it’s time to replace the two “AAA” batteries that power the unit (although measurements will remain valid for several hours after the light appears). To replace the batteries, follow the instructions on p. 5. A fresh pair of batteries should typically power 120 hours of operation.The HHM301 is not equipped with an Auto Power Off circuit. To avoid draining the batteries, remember to set the converter’s rotary switch to the OFF position after each measurement session.Remove the batteries when storing the unit or when you do not expect to use it for a long time (months rather than weeks).Do not operate the HHM301 in the presence of a flammable or explosive gas or near an arc welder or induction heater.After subjecting the instrument to a large change in ambient temperature, wait at least 30 minutes before making measurements to guarantee the accuracy of readings.Do not disassemble the HHM301 or immerse it in water.Make sure that the probe, converter and test leads are clean, dry and free of surface contamination before using the instrument.9FOR WARRANTY RETURNS, please have the following information available BEFORE contacting OMEGA:1.

核磁共振主机磁体系统硬件参数配置
核磁共振主机磁体系统硬件参数配置一、磁体系统产生强大，均匀的，稳定的静磁场，用于组织的磁化。
1.1、1.5超导磁体1，通电螺线管感生的磁场强度，与螺线管的匝数，通过的电流大小成正比。
根据焦耳定律，电流通过导体产生的热量，跟电流的平方成正比，跟导体电阻成正比。
如果用普通导体来产生磁场，所消耗的能量将十分巨大。
而超导现象中的零电阻效应，正好解决了线圈发热的问题。
在超导体中的大电流，能够长久运行，而不会转变成热量。
为了实现超导环境，就必须达到超低温。
目前的超导磁共振都是使用液氦来实现的，是目前超导的基础。
2，低温超导金属NbTi（铌钛）合金优良的超导电性和加工性能，其Tc 为9.3K，其使用已占低温超导合金的95%左右。
NbTi 合金可用多芯复合加工法加工成以铜（或铝）为基体的多芯复合NbTi/Cu（铌-钛与铜）超导线材（其Tc为4.2K，即-268.80C），可用于制造MRI 设备的超导磁体。
3，超导磁体首要由超导螺线管线圈（略称超导线圈）、高真空超低温杜瓦容器、和附属器件构成。
1.2、状态监控系统磁体线圈温度、应力、液氦液位、真空度、流量、杜瓦容器压力等参数值的变化。
1.3、紧急处置装置标记: 见场地要求1.4、氦气排放系统标记: 见场地要求1，失超管汇集了磁体的所有气体挥发管口，从磁体上端直通磁体间建筑外大气中。
平时，掉超管的作用就是排除废气。
一旦失超，磁体杜瓦容器中液氦挥发的全部氦气（每一升液氦可气化为1.25m3氦气）将从管中喷出。
如果掉超管预设尺寸不足、铺设路径不合理、欠亨畅、甚至堵塞，磁体因内部压力快速增高而被损坏的可能性将增大。
1.5、磁体外壳1.6、4K冷头,零液氦消耗技术1，绝对温度0K=-273℃，液氦沸点为-268.785 ℃；2，4K冷头+磁体：液氦温度4.2K=-268.8 ℃，可保证液氦不挥发；3，氦气最主要的来源不是空气，而是天然气。
原来氦气在干燥空气中含量极微，平均只有百万分之五，天然气中最高则可含7.5%的氦，是空气的一万五千倍。
