卡姆鲁普热量表说明书

食品营养标签能量计算方法国际统一单位，即焦耳(J)，或卡(cal)。

lkcal指1000g纯水的温度由15?上升到16?所需要的能量;1焦耳(J) 是指用1牛顿 (N)力把lkg物体移动lm所需要的能量。

“千焦耳”(kJ); “兆焦耳”(mega MJ)。

1kcal=4.184kJ 三大产热营养素卡价碳水化合物:17.15kJ (4.0614kcal)脂肪:39.54 kJ (9.3171 kcal)蛋白质:16.7kJ (4.0613 kcal)食品营养标签NRV%值计算: 对照GB28050-2011查出每种营养素对应的NRV值: 如能量 8400KJ蛋白质 60g ;脂肪 ?60g ;碳水化合物 300g ;钠离子 2000mg以统一阿萨姆奶茶为例:其营养标签成分表为4+1 核心营养素加能量: 项目每100ml NRV% 能量222KJ 3%=(222?8400)×100%蛋白质0.6g 1%=(0.6?60) ×100%脂肪1.5g 3%=(1.5?60) ×100%碳水化合物9.2g 3%=(9.2?300) ×100%钠40mg 2%=(40?2000) ×100%总能量=(0.6×4+9.2×4+1.5×9)×4.18?220 KJNRV(Nutrient Reference Values)，营养素参考值。

营养标签中营养成分标示应当以每100克(毫升)和/或每份食品中的含量数值标示，并同时标示所含营养成分占营养素参考值(NRV)的百分比。

2008年5月，中国卫生部颁布的“食品营养标签管理规范”说明:营养素参考值(NRV)是食品营养标签上比较食品营养成分含量多少的参考标准，是消费者选择食品时的一种营养参照尺度。

“食品营养标签管理规范”提供了食品标签营养素参考值(NRV)标准营养，素参考值是依据我国居民膳食营养素推荐摄入量(RNI)和适宜摄入量(AI)制定的。

MULTICAL® 603 M-Bus协议（V1.1）1.介绍1.1概况介绍•本协议只适用于MULTICAL 603 M-Bus。

•M-Bus模块有如下几种。

图1 图2图3•HC-003-20和HC-003-21可以使用电池和市电供电，但是HC-003-22只可以使用24V 和230V电源供电。

•HC-003-33可以用于连接24VAC常开或常关的电热执行器。

•支持的波特率有300,2400,9600和19200，8E1。

1.2通信间隔•MULTICAL603最小通信间隔为2s。

•为了确保电池寿命，通信间隔应大于10s。

不建议太频繁的通信。

1.3M-Bus格式M-Bus协议有以下几种帧格式。

1.4通信流程M-Bus抄表可分为下面四种抄表方式。

每块表都有一个独立的一级地址，一级地址通信最多可连接250块表。

➢按照二级地址通信二级地址（序列号）通讯是对一级地址通讯的扩展。

当仪表数量过多时，一级地址无法满足通讯要求，此时需要通过二级地址进行扩展。

与一级地址通讯不同，使用二级地址通讯时首先要通过二级地址“选择仪表”。

选择仪表成功后，便可通过一级地址“FDh”与被选中仪表进行通讯。

通讯结束后还要发送“取消选择” 命令，以释放一级地址“FDh”，以备继续与其他仪表通讯。

具体流程如下：➢点对点通信点对点通信仅用于采集器只连接一块表时，一级地址统一使用“FE”，抄表流程与一级地址通信完全相同。

➢广播通信广播通信用于对仪表参数统一配置的情况下，如修改仪表的时钟，修改仪表的波特率等。

广播通信时一级地址统一设为“FF”，广播通信只需要发送修改参数命令，仪表没有应答。

1.5一级地址出厂默认的一级地址为热量表SN号的后三位。

如果后三位数值在001~250之间，则就认为此数值为一级地址。

如果后三位数值大于250，则取后两位数值作为一级地址。

2.常用M-Bus指令2.1选择仪表指令SND_UD -> ACK请求命令：68 0B 0B 68 53 FD 52 NN NN NN NN HH HH ID MM CS 16应答命令：E5命令解析：此命令使用二级地址选择仪表，选择成功后可进行数据请求及配置命令。

*********************技术数据表HM R系列涡轮流量计配英制内螺纹2应用HM R 涡轮流量计系列（R 是指英制内螺纹）用于连续和非连续流速测量。

主要用于润滑性和非润滑性介质的测量。

这种流量计尤其适用于低和中等粘度液体的测量。

如水、乳化剂、乙二醇混合物和轻质燃油。

甚至可以测量低温流体。

涡轮流量计生产期间，仅使用可以耐腐蚀性液体的高级钢。

结合使用碳化钨轴承，HM R 可保证进行最佳准确测量，即使在最苛刻的应用条件下，也能保证极长的使用寿命。

结合使用多种涡轮叶轮尺寸和叶片几何造型，可以获得多种尺寸，从而具有较大的测量范围。

因此，HM R 可完美适用于测量、监测、混合和给药领域的各种应用。

通过较短的响应时间、非常动态的性能和高度测量准确性，即使在最苛刻的应用条件下，也能够确保准确校准并控制流速。

涉及到危险区域应用时，我们依据ATEX 、IECEx 、CSA 和其他标准要求，提供高度安全的传感器和Ex 防护放大器。

获得了EAC （TR-CU ）等其他认证。

原理和设计涡轮流量计（HM ）是基于福特曼叶轮计原理的体积测量计。

可通过平均流速，记录流经管道的流速。

介质在轴向方向上朝着涡轮叶轮流动，并旋转。

自由旋转的叶轮的转速，在较大范围内与平均流速直接成正比。

涡轮叶轮质量较轻，因此可确保对流速变化做出非常快速的响应和非常动态的反应。

两个整流器可产生准层流，从而提高测量准确性。

涡轮叶轮的速度通过外壳上非接触式的传感器技术（换能器）获取。

这一传感器系统可不断变化，以适应不同应用的要求。

例如，也可以提供指示流向的信号。

可采用每体积单位的脉冲进行分析。

这一流量计的校准系数（K-系数）描述了每个体积单位对应的准确脉率。

为了测定一个流量计的具体校准系数，我们在交货之前，在内部校准了每一个流量计。

校准期间，考虑了客户指定的操作粘度。

我们提供的每个流量计均随附一份相应的校准证书。

KEM 涡轮响应时间短，响应时间根据标示宽度的不同，介于5至50 ms 之间，可促进精确灌装。

1HIGH TEMPERATURE CLOTH-FACED INFRARED PANEL HEATERSOMEGALUX TM QF Series heaters are very popular infrared panel heaters used in a wide variety of applications. The QF Series panel heaters’ radiant surface is constructed through a patentedprocess using bonded high temperature cloth quartz. A black coating is applied to the face of the heater for greater emissivity. A 2.5 cm (1") thick ceramic fiber refractory board is grooved out to support the precision resistance coils.The resistance coil is then housed into the grooved-out refractory board. A layer of durable, high temperature, cement is used to bond the quartz face to the resistance coils as well as to the refractory coil support. The resistance coils used are an iron/chromium/aluminum alloy which can operate up to 1315°C (2400°F). These are then welded to stainless terminals which are routed to the back of the heater for external electrical connections. The welding insures the best possible electrical path. By changing to stainless buss bars and terminals, the conductivity is increased, insuring less heat buildup in the terminals. The heater board is then backed up by a high temperature insulation to prevent back heat loss. Finally, this is all packaged in a sturdy aluminized steel frame.U 870°C (1600°F) Maximum Operating Temperature U B lack Quartz Ceramic Cloth Face U O utput Wavelength Between 2.5 and 6 Microns U N o External Reflectors RequiredCHOOSING THE RIGHT IR HEATER Not all infrared heaters are alike. Here is a list of some of the most important questions to answer when determining which heater to choose.1. R ESPONSE TIME: How quickly do heaters need to reach operating temperature? IR heaters can reach operating temperatures as quickly as 2 seconds or take as long as 1 hour. Most take between 5 seconds and 10 minutes.2. P OWER REQUIREMENTS: What watt density (usually referred to as watts per square inch) is required?3. E NVIRONMENT: What will theambient temperature be? Will there be any flux, fibers, hazardous chemicals, or any other matter disturbing the environment? 4. C ONTROL METHOD: IR heaters can be controlled one of two ways:1 having the heaters on a percentage timer (open loop) and 2 through the use of a temperature control (closedQF SeriesShown with the CN9000A Series Controller.loop) method. The temperaturecontrol method is the most accurate way to control heaters and keep them at a consistent temperature. If you choose temperature control, you will have to decide whether to use a thermocouple or a pyrometer to measure temperature.5. P ROCESS NEEDS: Is it a conveyor, indexing, or a stationary process? Does the process call for a cleanable surface on the heater? Are zones in the individual heaters required? Compensation?6. A PPLICATION PROCESS: What exactly is the application? Are you trying to cure something? Melt something? Cook something, etc.?7. S PACE RESTRICTIONS: Is space limited?* Specify voltage, i.e. insert 240 for 240V or 480 for 480V.Ordering Example: QF-061810, 15 x 46 cm (6" x 18") 1080 Watt heater, 10 W/in2 Watt density that may be powered by either 120 Vac or 240 Vac single phase.2* Specify voltage, i.e. insert 240 for 240V or 480 for 480V.† This heater has two junction boxes at opposite ends of the panel.Ordering Example: QF-123625/240, 30 x 91 cm (12" x 36") 10800 Watt 3-phase heater, 25 W/in2 Watt density, 240 Vac.3QF SERIES INFRARED PANEL HEATERSCONSTRUCTION1.
