美瑞 М1500数字压力传感器手册说明书

DigitalPressure TransmitterM1500 + Meriam = Performance you can rely on!Meriam’s compact, M1500 Analog or Digital Pressure Transmitters are ideal for pressure measurement needs from 10” H 20 to 3000 PSI Full Scale. Output options include digital (RS-232, RS-485 and USB) or analog (mA or V DC). Choose from differential (dry/dry or wet/wet), gauge, compound or absolute pressure types – see the table below for complete details. Typical NIST traceable digital accu-racy is ±0.025% of F.S. including all effects of linearity, repeatability, hyster-esis and temperature from -20º to +50º C (-4º to +122º F).Digital output options for the M1500 deliver accurate pressure measure-ment to compatible receiving devices. Choose RS-232 single point or RS-485 for networks up to 255 devices. M1500 connections are made via terminal block or DB-9 serial port. The USB digital communication option also pow-ers the M1500 via high power USB ports or powered USB hubs.Software is included for initial setup and support. Meriam Serial Protocol (MSP) or Meriam DLL can be used to send and receive information. Implementation Guides are available at (see Resources / Application Notes).Analog output models are also avail-able. Output accuracy is typically ±0.035% of F.S. The user may config-ure the M1500 for 0 – 5 VDC or 4 – 20mA output. Two SPST opto switches are included. Analog units are config-ured using a USB Mini A Connector and the included Meriam Setup Utility. The utility supports initial configura-tion, zeroing, recalibration and other functions.For wider pressure range require-ments, model M1502 with digital out-put incorporates two pressure sen-sors. Most combinations of AI or CI type pressure sensors are supported. See the table below for available rang-es. M1502 is available with RS-232, RS-485 or USB digital outputs - not available with analog output. A single software command returns both pres-sure readings. The M1502 reduces purchase price and installation costs when multiple pressure measurements are needed.(Orifice plate, Venturi, Accutube, Wedge)• Clean room pressure monitoringStandard AccessoriesP/N Z9A000003PN06 Support Disk including: - Meriam Setup Utility- Meriam Serial Protocol Implementation Guide - USB Device Drivers & Installation Instructions - LabVIEW® VI’s- Meriam DLLOptional AccessoriesP/N Z9P273Analog Starter Kit, 6 ft.

The Meriam M1500 Pressure Transmitter, as well as other pressure products from Meriam, are powered by the EPI™. This ensures you are getting a highly-accurate device capable of ±0.025% FS including all effects of linearity, hysteresis, repeatability and temperature over specified operating temperature range. NIST traceable certification is standard.

Mitral Valve Prolapse Syndrome (二尖瓣脱垂)

Mitral Valve Prolapse Syndrome (二尖瓣脱垂)

The mitral valve begins to prolapse when the reduction of
LV volume during systole reaches a critical point at which the valve leaflets no longer coapt; at that instant, the click occurs and the murmur commences. Any maneuver that decreases LV volume, such as a reduction of impedance to LV outflow, a reduction in venous return, tachycardia, or an augmentation of myocardial contractility, results in an earlier occurrence of prolapse during systole. As a consequence, the click and onset of the murmur move closer to S1. When prolapse is severe and/or LV size is markedly reduced, prolapse may begin with the onset of systole. As a consequence, the click may not be audible, and the murmur may be holosystolic. On the other hand, when LV volume is augmented by an increase in the impedance to LV emptying, an increase in venous return, a reduction of myocardial contractility, or bradycardia, both the click and the onset of the murmur will be delayed.

唯医FM  髋关节撞击综合症的诊治要点

唯医FM 髋关节撞击综合症的诊治要点唯医FM全新升级,强势来袭!本期唯医FM将为您陆续放送美国骨科医师协会(AAOS)精编教程性书籍《AAOS Essentials of Musculoskeletal Care5th》。

中国医师协会骨科医师分会(CAOS)已获授权出版中文版书籍,并已组织国内多个著名医院的医生完成了全文翻译,纸质版即将刊印,电子英文原版也会陆续在唯医网发布。

欢迎老师们登陆唯医网进行学习。

本期为大家放送教程节选内容:髋关节撞击综合症。

长按二维码查看完整译文一同义词股骨髋臼撞击综合症Femoral acetabular impingement (FAI)二定义髋关节撞击综合症,又称股骨髋臼撞击综合症,是由于髋臼缘与股骨头颈连接部骨质形态异常,在髋关节过度活动时两者不断的发生接触、碰撞,导致髋臼盂唇及软骨损伤。

有研究显示,微小的骨质结构异常导致持续不断的微小创伤,逐渐发展为盂唇的撕裂。

Hip impingement, or femoral acetabular impingement (FAI), occurs when areas of osseous deformities on the acetabular rim, the femoral head-neck junction, or both abut at extremes of hip motion and cause injury to the acetabular labrum and and cartilage. Studies havedemonstrated that most labral tears occur after repetitive microtrauma as a result of these subtle structural deformities.三临床表现髋关节撞击综合症多见于运动爱好者,从青少年到中年均可发病。

The recent increase in the use of speed control of ac induction motor for variable speed drive using pulse width modulation (PWM) inverter is due to the advent of modern power electronic devices and introduction of microprocessors. There are many advantages of using ac induction motor for speed control applications in process and aerospace industries, but due to fast switching of the modem power electronic devices,the parasitic coupling produces undesirable effects. The undesirable effects include radiated and conducted electromagnetic interference (EMI) which adversely affect nearby computers, electronic/electrical instruments and give rise to the flow of bearing current in the induction motor. Due to the flow of bearing current in the induction motor,electrical discharge machining takes place in the inner race of the bearing which reduces the life of the bearing. In high power converters and inverters, the conducted and radiated emissions become a major concern. In this paper, identification of bearing current due to conducted emission, the measurement of bearing current in a modified induction motor and to minimize the bearing current are discussed. The standard current probe, the standard line impedance stabilization network (LISN)), the electronics interface circuits are used to measure high frequency common mode current,bearing current and to minimize the conducted noise from the system. The LISN will prevent the EMI noise entering the system from the supply source by conductive methods, at the same time prevents the EMI generated if any due to PWM, fast switching in the system, will not be allowed to enter the supply line. For comparing the results with Federal Communications Commission (FCC) and Special Committee on Radio Interference (CISPR) standards, the graphs are plotted with frequency Vs,line voltage in dB μV,common mode voltage in dB μV and the bearing current in dBμA without and with minimizing circuits.Keywords. EMI;a.c.drives; bearing current.┊┊┊┊┊┊┊┊┊┊┊┊┊装┊┊┊┊┊订┊┊┊┊┊线┊┊┊┊┊┊┊┊┊┊┊┊┊1.IntroductionWith the development of power electronic devices like the insulated gate bi-polar transistor (IGBT), the power MOSFET and the advances in microprocessors, the ac induction motor is becoming popular in variable speed drives with PWM inverter circuits. Since the rise time and fall time of the IGBT are less than 200 nanoseconds, the dissipation loss across the device becomes very less and there by increases the performance of the circuit. However, due to the fast switching action of the device the dw/dt of the inverter output becomes large. This high dw/dX voltage transition coupled with parasitic stray capacitance in the system causes high frequency line to ground current or common mode current and hence bearing current; introducing large EMI in the system.In figure 1,Ilg (the magnitude of ground current) depends on the cable capacitance, machine capacitance,parasitic capacitance of the devices, the output voltage rise time (tr ise) and the system voltage, V oltage gets induced in the rotor shaft of the induction motor due to fast switching. This induced voltage generates circulating current and flows to the ground through the bearing resulting in an electrical discharge machining (EDM) action at the inner race of the bearing.Due to the EDM, the life of the bearing reduces. The common mode voltage Vng (figure 1) can be measured from the star point of the stator winding of the induction motor (IM) or connected node of three 1MO resistors to the ground in case of the IM connected in delta. The reasons for common mode voltage generation are already discussed.It is noted that the sum of sinusoidal balanced phase voltages in a 3-phase IM at the star point is equal to zero. Therefore,Vng=(Van+Vbn+Vcn)/3 ⑴Common mode current=Cdν/dt⑵┊┊┊┊┊┊┊┊┊┊┊┊┊装┊┊┊┊┊订┊┊┊┊┊线┊┊┊┊┊┊┊┊┊┊┊┊┊Where ‘C’ is the total capacitance of the system and V an,V bn and V cn are the voltages between the respective phases and the star point in the stator winding2.Existing conducted emission, bearing current identification and measurement methodsV arious methods have been proposed to reduce the conducted emission common mode voltage and the measurement of bearing current. An output reactor connected to the inverter out put reduces the dv/dt of the inverter output voltage, which in turn reduces the common mode voltage at the star point of the IM and the flow of bearing current. Wious configurations of L-C filter have been reported. The inductance ‘L,and capacitance ‘C’ are designed according to the permitted insertion loss for the given power rating of the inverter. The draw back of the filter method is the voltage drop across the filter.In the passive filter method, the transformer secondary should be isolated for its successful operation and this is not possible in many process/engineering industries. An active common noise canceller has been tried to eliminate the conducted emission common mode voltage produced by the PWM inverter. The active common noise canceller superimposes a compensating voltage applied at the star point. This has the same amplitude as the common mode voltage produced by the PWM inverter but has opposite polarity; hence the common mode voltage applied to the load is cancelled completely. However, this method is suitable only for low voltage/power applications due to the resistive current sensor.Julian proposed a filter circuit for reducing the common mode voltage.This filter circuit is based on current sensing and it operates a fast transistor amplifier for the current compensation. Significant attenuation of the common mode voltage occurs.The method presented in this paper is different from earlier methods. Here,the phase current is sensed by the individual current transformer (CT) and is suitable for any voltage level. Since the CT is used for sensing the phase current there is no voltage drop in the sensor there by there is no reduction of terminal voltage applied to the IM.In tiidr circuit, the primary winding of the transformer is connected in series in each of the phases. Since the circuit uses the transformer, there is voltage drop due to the phase current of the IM, hence the terminal voltage applied to the IM gets reduced. The circuit is also used to reduce the common mode voltage and the common mode current at the star point of the IM. But this circuit is useful for the low voltage and low power applications.In the present work,the standard LISN,the standard current probes are used and the results are compared without and with the common mode voltage reduction circuits for the PWM inverter used for variable speed ac IM drives.┊┊┊┊┊┊┊┊┊┊┊┊┊装┊┊┊┊┊订┊┊┊┊┊线┊┊┊┊┊┊┊┊┊┊┊┊┊Julian proposed a filter circuit for reducing the common mode voltage.This filter circuit is based on current sensing and it operates a fast transistor amplifier for the current compensation.

基于小波阈值和ACMD的滚动轴承瞬时转频估计

基于小波阈值和ACMD的滚动轴承瞬时转频估计

第34卷第2期石家庄铁道大学学报(自然科学版)Vol.34No2 2021年6月Journal of Shijiazhuang Tiedao University(Natural Science Edition)j un.2o21基于小波阈值和ACMD的滚动轴承瞬时转频估计路飞宇s胡鑫磊1,刘素艳12,马增强12((.石家庄铁道大学电气与电子工程学院,河北石家庄050043;(2.石家庄铁道大学省部共建交通工程结构力学行为与系统安全国家重点实验室,河北石家庄050043)摘要:针对变转速工况下滚动轴承瞬时转频估计精度受噪声影响大的问题,提出一种基于小波阈值和自适应chirp模式分解(ACMD)的转频估计方法。

该方法首先利用小波阈值对原始信号做降噪处理,然后对降噪后的信号做ACMD#得到高时频分辨率时频谱,最后利用峰值搜索算法从时频图中估计瞬时转频。

通过对轴承仿真信号和实测信号的分析,证明了该方法能准确估计出瞬时转频,同时增强了噪声鲁棒性,为后续变工况轴承无转速计诊断工作奠定了基袖。

关键词:小波阈值;瞬时转频;抗噪性;ACMD中图分类号:TH133.33文献标志码:A文章编号:2095-0373(2021)02-0046-06变转速工况下滚动轴承故障诊断一直是难点,而诊断成功的关键在于获取精确的瞬时转频可以说,瞬时转频是滚动轴承故障诊断成功的基础参数,是实现无转速计故障诊断的重要前提。

因此,对滚动轴承瞬时转频估计具有重要意义。

当前对于瞬时转频估计的方法主要是基于时频谱分析来实现的,如郭瑜等⑵将短时傅里叶变换(STFT)和峰值搜索相结合,实现了电机的转频估计。

程卫东等囚利用线调频小波路径跟踪提取轴承瞬时转频(Wang et al4*对变转速振动信号做经验模态分解(EMD)变换,估计出瞬时频率,但EMD本身的模态混叠问题使得最终估计精度不高。

自适应chirp模式分解(ACMD)是一种基于变分模态分解(VMD)框架的非平稳信号处理方法囚,解决了VMD处理频率重叠的多分量信号效果不佳的问题,并且无需提前设定信号模态数,提高了时频分辨率[6]…近几年,ACMD在变工况旋转机械故障诊断领域得到了一定的应用[78],可以有效地提取多分量信号成分,准确地呈现信号内部频率与时间的关系,在瞬时频率估计上有很好的应用价值凹,然而,由于轴承运行环境中时常存在强噪声,单独的ACMD算法处理滚动轴承振动信号具有明显抗噪性不足的现象。

Basic topology of a frequency converter
Main advantages: •high efficiency (up to 98%) •wide speed range with good regulation •possibility of connecting several motors •load sharing possibility by using a common DClink •low sensibility to line transients
Voltage ringing overshoot occurs at the motor terminals due to pulse reflection phenomena in the long motor cable. The peak voltage can reach values of up to twice the DC-link voltage (2*Vdc).
In a pulsewidth-modulated voltage-source inverter (PWM-VSI) the common-mode voltage is always either +/- Vdc/6 (during an active vector) or +/- Vdc/2 (during a zero-vector).
• the level of the voltage applied to the main isolation (Upeak) • the rise-time tr determines the inter-turn isolation • Short risetime results in voltage unevenly distributed through the coils Following aggravating factors are usually associated
