JUMO Quantrol LC100 LC200 LC300式通用PID控制器系列简要描述说明书

Page 1/12JUMO Quantrol LC100/LC200/LC300 Universal PID Controller SeriesBrief descriptionThe Quantrol series is available in the three DIN formats 48mm x48mm, 48mm x96mm, and 96mm x96mm. It is used for two-state and three-state control applications as well as for the control of regulating valves or SCR power controllers via a continuous controller output.The universal analog input for RTD temperature probes, thermocouples, or current/voltage sig-nals is user programmable. The setpoint value, the actual value, and all parameters are dis-played on two seven-segment LED displays (red/green) with one or two decimal place(s). The values can be displayed in °C or °F. Depending on the format, up to five relay outputs with a switching capacity of 3A / 230V or up to four logic outputs 0/14V are available. The switch po-sition of the relays or logic outputs is displayed using yellow LEDs. Different functions can be as-signed to these outputs. An analog output 0to10V or 0(4)to20mA is configurable as continuous controller output, actual value output, or setpoint value output. Using the binary input, the device settings and operation can be locked, a ramp or the timer can be activated, or self-optimization can be initiated. The supply voltage is optionally AC110to240V or AC/DC 20to30V.The controller has a ramp function with adjustable gradient for constant setpoint change. In ad-dition, a special firing curve for small pottery kilns can be used which allows controlled starting and time dependent firing. The user can enter setpoint values, gradient, and firing time directly at the device.The device can be connected to host systems or devices using the RS485 serial interface. In-stead of operating the device from the front, the user can also program the controller using the setup program and USB interface; this requires no additional voltage supply for the controller. The Quantrol series, like all JUMO controllers, is also equipped with reliable JUMO self-optimi-zation (autotuning).LC100 (702031) LC200 (702032)LC300 (702034)Block diagramOption 1Option 2Option 3Option 4X X X X Relay output (N/O contact) X X X X Logic outputX Analog outputX RS485 interface Special features•48 × 48, 48 × 96, 96 × 96 mm formats •Two-state/three-state and continuous con-troller•Sensor monitoring•Up to 5 outputs•Self-optimization (autotuning) for exact PID control•Manual/automatic mode•Configurable limit value monitoring (alarms)•Setpoint changeover•Level inhibit and key lock•RS485 interface (Modbus RTU)•Ramp and timer function•Firing curve for pottery kilns•Push-in controller insert•Setup interface (USB Mini-B)Approvals/approval marks (see "Technical data")Data Sheet 702030Data Sheet 702030Page 2/12DescriptionSelf-optimization (autotuning)Standard features include the tried and tested self-optimization (oscillation method), which makes it possible for the controller to be matched to the control loop by a user who is not a control technology expert. Here, the re-action of the control path to the specific vari-able changes is evaluated and the controller parameters proportional band, reset time, de-rivative time, cycle time, and filter time con-stant are calculated.Ramp functionThe ramp function is used for a constant change of setpoint value w up to the ramp limit value SP (entered setpoint value). A rising or a falling edge arises depending on the actual value at the time of ramp start t0. The slope is defined by a gradient which is entered during the controller configuration.Firing curveThe firing curve is used for controlled starting and time-dependent firing of small pottery kilns. The user can enter setpoint values, gra-dient, and firing time directly at the device.Limit value monitoringThe controller is equipped with two limit value monitoring functions, each with eight configu-rable alarm functions. Any analog signals can be selected as actual and setpoint value from a selector. When a limit value is exceeded, a signal can be displayed or an internal control-ler function initiated. With the limit value mon-itoring, extensive alarm and limit valuefunctions can be implemented.TimerThe timer is started manually or automatically (after power on, for example). When the timer expires, the timer output signal changes its state (configurable). The timer can be used to implement functions like time-limited control or setpoint changeover.Setup programThe setup program provides the user with aneasy and comfortable way to configure the controller using a PC.The PC has to be connected to the controllers USB interface (Mini-B type) with a USB cable.Thereby the controller is powered over the USB interface. As a result, no mains supply is required during the configuration.Data Sheet 702030Page 3/12Controller parametersAll the parameters and their meanings are included in the table. Some parameters may be missing or meaningless for a particular type of controller.Technical dataThermocouple inputRTD temperature probe inputParametersValue range Factory setting MeaningProportional band 1 (Pb1)0 to 9999 digit 0 digit Size of the proportional bandThe controller structure is not effective with Pb = 0 (behavior identical to limit value monitoring).

Electronic transport in two dimensional graphene

arXiv:1003.4731v2 [cond-mat.mes-hall] 5 Nov 2010
(Dated: November 9, 2010)
We provide a broad review of fundamental electronic properties of two-dimensional graphene with the emphasis on density and temperature dependent carrier transport in doped or gated graphene structures. A salient feature of our review is a critical comparison between carrier transport in graphene and in two-dimensional semiconductor systems (e.g. heterostructures, quantum wells, inversion layers) so that the unique features of graphene electronic properties arising from its gapless, massless, chiral Dirac spectrum are highlighted. Experiment and theory as well as quantum and semi-classical transport are discussed in a synergistic manner in order to provide a uniﬁed and comprehensive perspective. Although the emphasis of the review is on those aspects of graphene transport where reasonable consensus exists in the literature, open questions are discussed as well. Various physical mechanisms controlling transport are described in depth including long-range charged impurity scattering, screening, short-range defect scattering, phonon scattering, many-body eﬀects, Klein tunneling, minimum conductivity at the Dirac point, electron-hole puddle formation, p-n junctions, localization, percolation, quantum-classical crossover, midgap states, quantum Hall eﬀects, and other phenomena.

工程应用实例
1. 信号流程
(1) 接收信号流程由射频部分送来的基带DQPSK调制信号 (f0=7.2 kHz)，进入带通滤波器MAX295EWE，滤除带外噪声，然后进入运算放大器(TL084)放大至适当电平(0～3 V变化范围)。放大后的信号由模数转换器AD7862进行量化，量化后的数据进入DSP芯片，通过软件编程进行DQPSK解调、维特比译码和解交织等，得到原始信息码。DSP将该信息码送给Intel8251A，转化成9.6 kb/s的UART数据流，最后经MAX232EESE转变成RS232电平(±12 V)送往数据终端。

在探伤时，重要的是缺陷信号和干扰信号比。为了获得需要的频率而采用滤波器，如图3.3.16(a)所示，需要进一步抑制干扰信号，可采用幅值甄别电路。把这一电路调整到裂缝信号正好能通过的状态，凡是低于裂缝信号都不能通过这一电路，这样干扰信号都抑制掉了。如图3.2.16(b)所示。
