177313-01-01 Bently Nevada TK-3接近系统测试套件

Bently Nevada TK-3接近系统测试套件模拟轴振动和位置，用于校准Bently Nevada监视器。除了验证监视器读数的操作条件之外，TK-3还用于接近探头的静态和动态验证。正确校准的系统确保传感器输入和产生的监视器读数是准确的。

该系统使用可拆卸的主轴千分尺组件来检查传感器系统和位置监视器校准。这种组件的特点是具有一个通用的探头安装架，可以容纳直径从5毫米到19毫米(0.197到0.75英寸)的探头。当用户以校准的增量将目标移向或移离探针尖端时，支架固定探针，并使用电压表记录前置器传感器的输出。主轴千分尺组件还具有方便的磁性底座，便于在现场使用。

振动监测器使用电机驱动的摆盘进行校准。位于摇摆盘上方的摇臂组件将接近探头保持在适当的位置。该组件使用通用探针架，与主轴千分尺组件使用的探针架相同。通过结合万用表使用接近探头的绝对标度因数，用户调整探头以找到存在所需机械振动量(由峰-峰DC电压输出确定)的位置。不需要示波器。然后，用户可以将振动监控器的读数与接近探头观察到的已知机械振动信号输入进行比较。TK-3的机械振动信号峰峰值范围为50至254微米(2至10密耳)。

The Bently Nevada TK-3 Proximity System Test Kit simulates shaft vibration and position for calibrating Bently Nevada monitors. In addition to verifying the operating condition of monitor readouts, the TK-3 is also used for both static and dynamic verification of proximity probes. A properly calibrated system ensures that the transducer inputs and the resulting monitor readings are accurate.

The system uses a removable spindle micrometer assembly to check the transducer system and position monitor calibration. This assembly features a universal probe mount that will accommodate probe diameters from 5 mm to 19 mm (0.197 to 0.75 in). The mount holds the probe while the user moves the target toward or away from the probe tip in calibrated increments and records the output from the Proximitor Sensor using a voltmeter. The spindle micrometer assembly also features a convenient magnetic base for ease of use in the field.

Vibration monitors are calibrated using the motor-driven wobble plate. A swing-arm assembly located over the wobble plate holds the proximity probe in place. This assembly uses a universal probe mount, identical to that used with the spindle micrometer assembly. By using the absolute scale factor of the proximity probe in conjunction with a multimeter, the user adjusts the probe to find a position where the desired amount of mechanical vibration (as determined by peak-to-peak DC voltage output) is present. No oscilloscope is needed. The user can then compare a vibration monitor’s reading to the known mechanical vibration signal input viewed by the proximity probe. The mechanical vibration signal from the TK-3 can range from 50 to 254 μm (2 to 10 mils) peak-to-peak.
