KINAXWT707角位变送器安装在核电站记录燃油阀在柴油上的位置
KINAXWT 707防爆型角位变送器安装在核电站一根燃料棒上，用来记录燃油阀在柴油上的位置。在关键的设备上需要至少三年不可出现问题的地方，选用的很大一个优点除了精度以外，就是耐用抗磨损。
我们来讲一个实际的应用案例，角位变送器应用于捷克的能源生产。
旋转角度测量传感器带有非接触式电容传感系统的测量传感器，用于获取轴的角位置，KINAX WT 707安装在一根燃料棒上，用来记录燃油阀在柴油上的位置。该发电机采用Z40六缸低速柴油机驱动，输出功率为3MW。杜科瓦尼核电站共有12个柴油发电机站。这些保证了如发电厂发生故障，则构成第2类安全系统。KINAXWT 707，测量范围为0~30°，输出4~20 mA的信号发送到控制系统，用于可视化和存储测量数据。需要存储的数据连同其他重要数据-评估电气/机械调节器和柴油发电机在所需测试和负荷下正常运行中的有效性。
角位变送器是机械和电子元件之间的连接装置。它们将角度位置信号按照标准化的0/4-20mA信号输出。通过诸如电位计、霍尔传感器、光学编码器或感应系统等不同的程序实现的。德国GMC公司的角位变送器拥有独有专利的电容式传感系统主要优点是耐用抗磨损。此外，轴上不需要驱动扭矩。Kinax2W2可编程角位置变送器版本可以通过软件在任何位置设置零点。软件还包含一个线性化功能，允许用户自定义线性化曲线。
在杜科瓦尼核电站的柴油发电机站运行角位变送器，必须满足以下要求：
■ 输出信号为4-20mA
■ 精度<0.5%
■ 高机械阻力
■ 坚固耐压
■ EMC
■ 防震
■ 便于组装和拆卸
■ 抗震特性符合IEC标准
■ 抗温湿度等环境影响
■ IP65防护等级
■ MTBF > 1000 h
此外，KINAXWT 707符合IEC/EN 601226*B级的所有技术规格。

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 |
