6、asured, its extensibility, thickness and pulling resistance have to be considered.选择剖面（表面）时,必须考虑该物体的坚固度,可延长性,厚度,以及抗拉力.Furthermore the slippage is also influenced by the width of the leaning surveying wheel, the contact pressure, the tensile stress in the item to be measured and the angle of belt con

7、tact. The position of the surveying wheel should be made so that the direction of the material flux is away from the bearing point of the transmitter.此外，倾斜的测量轮宽度,接触压力,物体的张应力( 需测量)和皮带包角的角度也会影响到滑动。为使材料流向远离发射器的承受极点,测量轮要仔细安装.Meter counter计米表计米表Direction of material flux材料流向Surveying wheel测量轮different pr

Speedometer generators are often produced together with the drive motors as one unit.速度计是用来测量速度的.就象直流发电机和交流发电机一样,速度计也需要永久的励

10、磁和集电极以及电刷.因速度计的唯一任务就是制造电压,所以它较小.由此发电机制造的电压是以电子测量,以不间断电流的速度和数量分别显示.速度计生成器通常与驱动马达作为一个整体生产出来.

11、线Oscillation fork 震动叉Test magnet 检测磁铁Shift point移转点The oscillation fork is excited in a piezoelectric way. In the air it oscillates with its natural frequency, however, is it touched with liquids, the oscillations change.震动叉是以压电的方式震动。空气中以自然频率震动,但当遇到液体时, 震荡就会发生变化These changes are evaluated electronic

12、ally and create the shift signal. When the test magnet is put at the point marked, the oscillation fork reacts as if it is covered with liquid.变化是以电子方式进行测量并会产生移转信号,当检测磁铁放在标示处,震动叉就会像被覆盖上液体那样产生反应.Overflow protection防止溢出防止溢出The overflow protection is a so-called float. It consists of a hollow ball in w

13、hich liquid can enter and which is connected to a circuit. In this hollow ball there is another ball which is also connected to the circuit. When there is liquid in the float the circuit is open and the pump is switched-off. However, when the small ball touches the hollow ball the circuit is closed

14、and the pump lifts liquid into the pump bucket.防止溢出装置又称 浮子，是一个与电路相连，可内盛液体的空心球. 球内还有个与电路相连的球.当浮子中有液体时,电流是开通的,泵是关闭的.然而,当小球与空心球接触时,电路断电,泵将液体压入泵桶中.

15、 influences the coating speed of the lacquer on the printing roller. The measurement is done by an oscillating bar which serves as sensor. This bar is kept in oscillation by constant electric energy. The oscillation amplitude is changing according to the viscosity of the lacquer, and the electronic

16、controls the oscillation and processes the change of amplitudes.As the viscosity highly depends on the temperature the corresponding measurement temperature has always to be indicated.由于粘性会影响到印刷辊上的漆的喷涂速度,所以粘度的测量非常重要.由作为传感器的振动杆来进行测量. 杆由恒压电源保持振动.振幅随漆的粘度而变化.电子控制着振动和振幅的变化。由于粘性受温度影响极大，相应的测量温度也要显示.Lacquer

At the catalytic active element the part of gas in the air is combusted more or less intensively - depending on the concentration. By this combustion of gas the characteristic te

19、mperature of the element increases which leads to an increase of the electric resistance. By this the circuit is brought out of balance and current is conducting which is put into relation to the existing gas concentration. 可燃性气体和水蒸汽通过熔结金属盘到达测量室。那有一个特殊转炉与第二元件形成一段电路支路，就接触反应性来说，此元件是惰性的。它用来补偿在传感器附近由温度、

20、压力、和湿度造成的震动。空气中接触反应性活跃的元素气体由含量的多少决定其或多或少的燃烧量。在气体燃烧时，元素的特性温度会上升并会引起电阻的上升。至此电路不再平衡，电流工作与现有的气体含量相关。Sensor (concentration of solvents in the air)传感器（空气中溶剂的含量）Gas warning device 气体警报装置 display显示器Pre-alarm预警UEG 45%Main alarm警报UEG 50%Thermocouple热电隅热电隅The thermocouple consists of the valve and the thermost

21、at which are screwed together through two strap halves. The temperature of the medium to be adjusted creates a pressure in the thermocouple which is corresponding to the actual value. This pressure is transferred through the trunk line (5) on the working medium andre-formed into a force. The change

22、is effected via the adjusting bellows (4) and the working medium pin (2) on the cone bar (1). By turning of the set-point adjuster the reaction point is changed via the spring (3). This results in the following: the valve cone passes through its stroke within a higher or lower range of temperature.

23、热电隅由阀和自动调温器组成，阀和自动调温器是由两段带子拧紧相连。待调节的媒介温度在热电隅中产生与实际值相应的压力。压力通过工作中介的中继线（5）传导并重新形成一种力量。变化受调整箱（4）、圆锥杆（1）上的工作中介栓（2）、的影响。旋转固定点调节器，反应点可以通过弹簧（3）改变。结果如下：圆锥阀在温度范围内完成冲程。LeadingScrew主螺栓主螺栓5Valve spring弹簧阀弹簧阀Discharge bellows排气风箱排气风箱31244Pressure regulator with display带显示器的压力调节器带显示器的压力调节器The medium to be measure

24、d flows from the left side into the pressure regulator in order to build up in the lower part a pressure in the valve (1). This pressure has an upward effect and is passed on through a plastics diaphragm (2) to a spring (3). Here it causes by a spiral spring a deflection of the hand at the manometer

25、. By the adjusting screw (4) and the spring a counter pressure can be adjusted so that the pressure in the tube does not exceed a certain value.要测量的中介物从左边流入压力调解器，从而在在阀（1）下部中，形成压力。该压力有向上的冲力，并由一塑料膜（2）传到弹簧处（3）。在此，通过螺旋形的弹簧造成压力器指针的偏转。通过调节螺杆（4）和弹簧，计量压可以调节以保证管中的压力不会超过一定的量。Spring pressure plate弹簧压力板1234Filt

At the beginning of the production the foil colour is read in the sensor and stored. When there is now a change of colour (void, etc.) during production, the sensor recognises it and passes it on to a monitoring unit. The void is recognised!识别断档的仪器为一个可以辨认、储存、和区别颜色的感应
