Specification Sheet SS-CP-2385-USPRODUCT DESCRIPTIONThe AMC910 multi-purpose calibrator is the right solution for high precision signal, temperature, and pressure calibrations, as it combines the power and features of a laboratory calibrator, with the addition of an isolated measurement channel.The AMC910 calibrator offers laboratory grade accuracy, high per-formance and simple-to-use functionalities. With the optional exter-nal pressure modules, the system may be taylored to address all possible calibration needs.FeaturesThe JOFRA AMC910 not only offers temperature and pressure calibration features, it combines sourcing of current and voltage, measurement of millivolts and resistance with a second completely isolated measurement channel for a single laboratory calibration instrument unmatched in ver-satility, performance, and value. This flexibility means that only one unit is needed for calibration or verification giving the confidence needed for test instruments as well as for field calibrations.The JOFRA AMC910 has the ability to store up to 9 setpoints for each output range. The setpoints can be selected manually or automatically stepped at timed intervals. The AMC910 also features an intuitive, easy-to-operate user interface and computer control through the RS232 or IEEE-488 interface for automated production testing. The unit sources DC voltage and current for multifunction workload coverage, enabling calibration of data loggers, strip chart recorders, multi-meters, handheld calibrators, and other industrial instruments. This is the cost-effective solution for multiple calibration needs.Model AMC910Advanced Multi-purpose CalibratorN ow wi t h s ou r c i n ga n d me a s u r i n g i no n e i ns t r u m e n t2Direct keyboard entry (1)The JOFRA AMC910 provides simple, front-panel entry of mode,range, and value. Using direct keyboard entry (1), the exact valuedesired is entered using the numeric keys, and the ENTER keyis pressed to set the output to that value. Whichever way youchoose, setup is simple and fast. In the voltage output mode, theJOFRA AMC910 auto-ranges on the entered value for maximumaccuracy at all times.Curser entry (2)Using cursor entry (2), the LEFT/RIGHT arrow keys are used tomove the cursor under the digit in the display to be changed. TheUP/DOWN arrow keys increment/decrement the value at the cur-sor position.Choose the mode you want (3)Voltage ModeThe JOFRA AMC910 offers four precision voltage output ranges(100mV, 1V, 10V, and 100V) all with ±0.003% of reading ±0.001%F. S. accuracy. These ranges are ideal for calibrating a broadrange of DC voltage instrumentation. Additionally all voltageoutputs settle to full specification in less than 200ms making theJOFRA AMC910 ideal for automated calibration systems.An automatic stand-by mode (3) assures that output voltagesabove 30VDC must be acknowledged by the operator before thevoltage appears at the output jacks. The stand-by mode is alsotriggered if the output current compliance is exceeded, therebyprotecting the device under calibration.Current ModeThe JOFRA AMC910 features a precision current output range(100mA) that offers 0.01% accuracy, which is ideal for calibratingprocess instrumentation especially 4 to 20mA equipment. Witha full 12 volts of compliance at 100mA virtually any precision DCcurrent measuring device can be calibrated using the JOFRAAMC910. Like the voltage ranges the current range offers quicksettling time and an operate/stand-by mode.Thermocouple ModeThe JOFRA AMC910 can read and source any of 11 typesof thermocouples. Its T/C input and output is Cold JunctionCompensated, using an ultra-stable PT-1000 sensor.RTD ModeThe JOFRA AMC910 can read and source 9 RTD types as well asYSI-400 and Ohms for non-standard curves. Probe coefficients (A,B, C, and R0) can be entered directly, with storage for up to fivecustom curves and one SPRT curve. The performance of the JOFRAAMC910 in the RTD mode compares to dedicated RTD measure-ment instruments. Unlike low-cost, less accurate RTD instruments,the display in the JOFRA AMC910 is always active, reading to threedecimal places, using polynomial averaging to extract a high accu-racy signal. The result is a very high accuracy reading.Pressure ModeSignal calibration capabilities of the JOFRA AMC910 include, cur-rent, voltage and resistance. In temperature mode, the unit can readand source any of 11 types of thermocouples and 9 RTD types aswell as YSI-400 and Ohms for non-standard curves. In pressuremode, the instrument operates with all JOFRA APM modules andcovers pressure ranges from vacuum to 700 bar / 10,000 psi, select-able through more than 60 different pressure modules, representingvacuum, absolute, gauge and compound pressure types as well asSetpoint Control (4 and SPT)A SHIFT key (4) provides easy accessto the setpoint controls of the JOFRAAMC910. Up to nine setpoints canbe defined for each output mode andeach thermocouple and RTD type.Setpoints are recalled individually atthe touch of three buttons, SHIFT (4),SETPOINT (SPT) button and then thecorresponding numeric keys 1-9. Anynumber of sequential setpoints canbe stepped through automatically,with complete control of dwell time.Either way, for rapid setup of repeat-able tests, no other instrument comesclose to the JOFRA AMC910.Remote Control (4)All of the JOFRA AMC910 operating functions can be accessedvia RS232, IEEE-488 or optional USB interface cable using astandard PC running Windows® HyperTerminal or other soft-ware using an ASCII protocol. Custom control programs maybe written using programming software such as C++. Switchingbetween LOCAL and REMOTE is as simple as touching theSHIFT (4) and LOCAL buttons.Rock-Solid StabilityThe accuracy of the JOFRA AMC910 is specified for both 90-dayand one-year intervals. Manual zero calibrations can be made onall T/C and pressure functions to eliminate offsets.Flexible Output (5, 6 and 7)Five-way copper alloy binding posts (5) provide a wide range ofconnection options. A standard pressure module connector isprovided (6), as is the CJC T/C mini-jack (7).Isolated Measurement Channel (8 and 9)The JOFRA AMC910 features a fully isolated measurement chan-nel which allows the user to calibrate process transmitters andsignal isolators. In reality it’s like having two instruments in one!This channel also incorporates a 24 volt loop power supply topower 2-wire transmitters and a HART interface resistor enablingdirect connection to HART communicators. Key features are:Two voltage ranges 10V and 100V DCMilliamp range 0 to 50mAMilliamp range with simultaneous 24 volt power (0 to 24ma)Selectable 250 ohm HART resistorAccuracy of 0.005% of reading on all ranges•••••3SPECIFICATIONS AMC910(1 year at 23°C ±5°C;

In all cases it is the responsibility of the user to employ safe working practices and verify that the system is safe before connection. Even isolated systems may exhibit significant capacitance which will become highly charged during the application of the insulation test. This charge can be lethal and connections, including the leads and clips, should never be touched during the test. The system must be safely discharged before touching connections.DESIGNED FOR EVERYDAY USETest leads are a key component of any precision instrument and that safety, long life, and the ability to provide reliable connections to a variety of test pieces found in everyday applications are of the utmost importance. Megger design test leads for both safety and practical operation.LOCKING HV INSULATED PLUGS/NON-REMOVABLE TEST CLIPSAll Megger 5 kV, 10 kV and 15 kV insulation testing test leads are fitted with unique locking HV plugs and non-removable test clips. This reduces the likelihood of a plug or clip inadvertently losing electrical connection and the capacitance of a long cable remaining lethally charged.With the arrows on the plug finger guard horizontal on the instrument as shown to lock. Twist 90º to to unlock. In addition,for the same reason, the test clips are not removable from the test lead.PRACTICAL INSULATION DESIGNMoving jaw fingers maintain the clips touch proof safety when clip is closed but flex back to allow metal teeth of the clip to contact test piece unimpeded when in use.Megger clip beingtested with IECstandard testfinger for creepageand clearance.PRACTICAL JAW DESIGNCurved jaws allow reliable connection around test piecesand flat jaw tips provide excellent connection and grippingof individual wires.OPTIONAL TEST LEADSMEDIUM AND LARGE TEST CLIPSTest leads above with medium and large size insulated clips are available supplied as an option in 5m, 8m, 10m and 15m lengths.

差压零位漂移对标准孔板流量计流量的影响摘要:天然气产销厂主要的计量方式采用的是变送器(流量管理器)配标准孔板的差压式流量计,该类型流量计的检定周期为一年,在一个检定周期内,仪表的差压零位会随着时间或温度而发生变化,这个微小的变化会对该类型流量计的流量计量产生何种程度的影响,是亟待研究的一项重要内容。
为此,通过在实验室内开展各项试验,对差压零位漂移进行数值模拟,找出差压零位漂移对不同气质,不同运行范围,特别是低限运行时的流量影响的规律,指导厂内各区站的日常检查。
并通过大量的试验及对试验数据的归类分析,找出了差压零位漂移对流量计量影响的规律。
关键词:差压零位漂移;标准孔板流量计;流量分析1现状调查1.1该类仪表的使用情况通过对全厂在用的流量计进行调查发现,我厂在用标准孔板流量计为170台,旋进旋涡流量计为61台,其它类型流量计,标准孔板流量计占到了全厂流量计总数的72.3%。
该类仪表的压力及差压变送器的精度均为0.2级。
1.2该类仪表的运行情况为了便于对该类型仪表的线性稳定性进行分析,我们选取了2台编号分别为T233648、T233651型号为2010TC的多变量变送器和2台编号分别为17961225、15841265型号为103的流量管理器近三年来的差压检定记录并对该表的线性度计算,整理汇总发现我厂在用的三合一变送器和流量管理器具有极佳的线性稳定性,所以得出结论:该类型仪表的差压零位发生漂移,将直接导致检定拟合曲线的整体漂移,也就是说,差压零位漂移量将直接导致各检定点的测量值发生与零位漂移量大小几近相同、方向也相同的变化量,从而对计量的数据产生影响。
2实验过程在该项目开展前,制定了详细的实验实施方案,并严格按照实施方案进行实施。
选取了一台编号为16970037型号为FB103的流量管理器来完成整个实验数据的采集工作,该表差压最大基本误差为0.03%,静压最大基本误差为0.02%,差压线性度为0.03%,静压线性度为0.02%,流量积算部分的最大基本误差为0.01%。
HART375手操器对罗斯蒙特3051系列变送器组态实训一、375手操器的使用按下图进行接线:1、变送器接线端子:左侧端子为24V电源正、中间端子为24V负(也称公共端)、右侧端子为检测电流信号端。
2、HART375手操器有两组插孔,一组为FF总线协议插孔另一端为HART协议插孔。
3、MCMC55 MC55是一台多功能校验仪,校验变送器时将变送器两个端子用导线连接到MC 上面标有2-W xmtr两个插孔上,按下MC5电源开关→D→D出现→设置窗口1和设置窗口2,窗口1一般设置为测量窗口、单位为mA,窗口2一般设置为压力窗口、单位可选择mpa、kpa、pa或其他压力单位。
选择完两个窗口后再按D键就可以校验变送器了。
4、在连接线路上串联一个250Ω的电阻为负载电阻,我们一般用电阻箱代替,把电阻箱旋钮拨到250Ω即可。
接完线检查无误,就可以通电对变送器进行组态和常规校验。
HART375手操器具体操作:1、打开电源开关等待375进入主菜单画面。
2、使用光标笔双击“HART应用栏”如果手操器与变送器通讯正常,则画面应转入在线状态。
此时双击“仪表设置”即可进入变送器的组态菜单仪表状态画面有五个选项:1双击“显示过程变量”后,你可以查看与变送器相关所有测量参数。
2进入诊断画面,你可以对也不进行各种校验及回路测试,另外变送器的各项报警也可以查看。
3进入“基本设置”你可以进行修改仪表位号;工程单位;变送器量程及阻尼时间。
因此,这是最常用的菜单,你可以双击5个选项的任何一个进入该菜单。
以下是菜单3:请注意:单击“左箭头”可以退回上一级菜单,单击“×”图标退回主HOME””退回到在线菜单(online,此菜菜单(此时可以关机),单击“HOME单为实时参数更新画面)。
3-1:修改单位:双击“单位“进入修改工程单位子菜单:ENTER””,这时候会告诉你使用光笔单击所选定的单位,然后单击“ENTER当前过程变量在该选定单位尚未发送至变送器之前仍然为原单位,提示你应在随菜单中进行发送(SEND),因此,见到提示后,即按OK则出现下随菜单:SEND””并在见到提示后,按OK,修改后的单位即下装到变送器中。
多功能校验仪校准TC及RTD通过优化环路校准测量系统,使其更好地支持温度检测元件的独有特征,能够大幅提高性能。
所有温度探头及其检测元件都是独一无二的,材料、结构、用途或者使用环境均各有不同。
这种独特性贯穿于传感器的整个使用寿命期间,表现形式为机械冲击和振动引起的漂移,或者暴露于被测材料时污染引起的漂移。
只有通过定期检定,才能适应这些差异和变化,提高总体测量性能。
在许多工业和商业过程中,温度的角色非常重要。
例如医药公司的灭菌、航空航天行业为确保最佳强度而进行的金属热处理、冷库中的温度检定,以及大气和海洋研究。
在所有温度测量应用中,传感器对结果的影响非常大;遗憾的是,在很多测量中,没有通过优化系统来获得温度传感器的最佳性能。
大多数过程温度测量是通过连接至变送器的检测元件实现的。
图1所示为常见配置的示意图。
在许多应用中,往往独立检定测量系统的检测元件,但这样往往忽略了将系统作为一个整体能够明显提高性能。
独立检定或校准检测元件的主要原因之一是这样做的效率更高。
利用电子热电偶(TC)或电阻温度检测器(RTD)模拟器,可简便、快捷地检定测量组件。
该方法不检定相关温度探头的性能,而是认为所有探头完全相同并严格遵守一定的标准。
在实际应用中,没有两个探头是完全相同的,它们全部会偏离理想标准,并且其特征随时间和使用发生变化。
Rosemount Inc.以表1为例,给出了关于644H型智能温度变送器可能实现的性能改善的信息。
为实现这一性能改善,为Rosemount 644H提供信息(Callendar Van Dusen方程系数),使其能够修正温度检测元件的独特性能,本例中为标准IEC751 Pt100传感器。
干井和微型恒温槽是检定温度探头及其他相关传感器的上佳选择,但是本身没有能力校准变送器的输出或读数装置,不能优化整个测量环路。
为了实现并保持上述的性能改善,需要一个热源,并结合能够校准变送器和读数装置的智能电子式过程校准器。
