KINAX WT707多功能角位变送器多个使用案例
KINAX WT707多功能角位变送器多个使用案例。适用于恶劣环境下的工业应用。KINAX WT707是一种非常坚固的绝对角度位置变送器，由于其独特的电容测量原理，特别适合在恶劣环境中的应用。它以非接触方式获取轴的角度位置，并将其转换成与测量值成比例的外加直流电。WT707带无接触电容式感应系统的测量变送器，用于获取轴的角位置。在测量输出端读取范围为4到20 mA的与负载无关的DC信号。由于其坚固的设计，KINAX WT707主要用于机械制造和造船。

符合Ex ia IIC T6的“本质安全”防爆保护，可在爆炸性环境中使用
用电位计调节量程/优化适应所需的量程
输出量特性：线性或特性曲线
驱动轴可以无限旋转：即使超出测量范围的上限值，也不会发生损坏。
坚固外壳中的表面安装装置：抗振动和冲击，适用于机械制造和造船业
具备海上执行能力（以前是GL，Germanischer Lloyd）
不久前，布鲁塞尔地铁(Figure2)以72km/h过弯道时产生很大噪音，法国铁路运输公司(S.T.I.B.)因此想要寻找一个系统来润滑弯道导轨。润滑可减少轨道磨损和降低噪音水平。
这个应用的核心是一个坚固的角位变送器KINAXWT707安装在火车转向架的轴承上，当向右转弯时，润滑右内轨道，当向左转弯时，润滑左侧轨道。角位置传感器的灵敏度足以在500米的长弯道和72公里/小时的相对高速下发挥润滑作用。
往气罐内装满液态氨是个细致活。装载过程中气罐一个小小的错误动作都会导致氨气的大量释放，对人和环境造成伤害，法国马津加德氨气工厂就成功使用了KINAXWT707角位变送器。WT707监测氨气填充过程中的气罐位移。为此，KINAX WT707安装在固定臂和活动臂之间的旋转点上。如果气罐移动导致活动臂移动超过±5...10cm(±1°)，这样的变化被传输到控制系统。触发器立刻执行安全操作，比如关闭充气管的阀门，发出警报并进行警报登记。
除此之外，KINAXWT707还有很多其它的应用，例如油罐或沼气池（易燃易爆环境）的液位测量，船舶上舵的位置测量，吊桥的倾角等等，我们的KINAX产品经受市场的多年验证，依然安全可靠的工作着。即使在恶劣的使用环境，也不会产生由于磨损原因的维修需要，大大节省了维修时间和成本。

Additional gear 2 : 1 to 144 : 1 Choose the full scale value of KINAX WT 707 (without gear) ME ≤ 150°. Limit of error: ≤ 0,5 % for ME ≤ 150° and ≤ 1,5 % for ME ≥ 150°. Determine the required reduction ratio to the following formula: n · 360 [°] i = Reduction ratio i = ME [°] n = No. of turns (end of range of object being measured) ME = Full scale value of KINAX WT 707 (without gear). If “ME” is higher but max. ≤ 150°) and “i” is as small as possible the the hysteresis error will be smaller. Example of calculation of the error of the hysteresis; known are: n = 4.1 rotations, i = 10, ME = 147.6° and j = approx. 1.0° j = gear backlash F % = 100% · j · i = 100 · 1.0 · 10 = approx. 0.68% error of the n · 360° 4.1 · 360 hysteresis Gear backlash approx. 1.0° for 2 ≤ i ≤ 12.5 approx. 1.5° for 12.5 < i ≤ 60 approx. 2.0° for 60 < i ≤ 1600 |
