TK-3E涡流系统校验仪

校验仪为便携式仪表，通常称作“摆频信号发生器”，用于对电涡流探头进行静态和动态校验。 静态校验通过附加的千分尺完成；动态校验通过一个模拟动态机械振动的特殊旋转“倾斜圆盘”完成。 由于多年来传感器功能的改进以及性能标准更严格，该系统无法按照API670 标准对传感器系统校验提供必需的精度。

TK-3E校准仪模拟轴振动和位移，用以校准监测器。它验证监测器读数装置的工作状态以及电涡流传感器系统的状态。一个正确的校准系统意味着的读数和传感器输入。 一个纺锤形千分尺用于检查传感器系统和校准位移监测器。与TK-3E 一同提供的探头安装接头固定探头，同时被测靶面以被校准的增量向着或远离探头端部运动。前置器的输出由电压计进行记录。

振动监测器使用马达驱动的倾斜圆盘校准。圆盘上面有一个摇臂保持器将电涡流探头固定。通过将保持器和探头调节到适当位置，可以使机械振动大小达到预期值。该机械振动由校准装置中的刻度盘千分尺测量（不需要示波器）。

振动监测器的读数可以与已知的机械振动信号输出（即千分表测出的读数）进行比较。TK-3E 测得的机械振动信号范围从50 到254 μm (2 到10 mils) 峰峰值。

TK-3E Eddy Current System Calibrator

The calibrator is a portable instrument commonly known as a "swing frequency signal generator", used for static and dynamic calibration of eddy current probes. Static verification is completed through an additional micrometer; Dynamic verification is achieved through a special rotating "tilting disk" that simulates dynamic mechanical vibration. Due to years of improved sensor functionality and stricter performance standards, the system is unable to provide the necessary accuracy for sensor system calibration according to the API670 standard.

The TK-3E calibrator simulates shaft vibration and displacement to calibrate the monitor. It verifies the working status of the monitor reading device and the status of the eddy current sensor system. A correct calibration system means reading and sensor input. A spindle micrometer is used to inspect the sensor system and calibrate the displacement monitor. The probe installation joint provided with TK-3E fixes the probe, while the measured target surface moves towards or away from the end of the probe in calibrated increments. The output of the proximitor is recorded by a voltmeter.

The vibration monitor is calibrated using a motor driven tilting disc. There is a rocker arm holder on the disc that holds the eddy current probe in place. By adjusting the retainer and probe to the appropriate position, the mechanical vibration magnitude can reach the expected value. The mechanical vibration is measured by a dial micrometer in the calibration device (without the need for an oscilloscope).

The reading of the vibration monitor can be compared with the known mechanical vibration signal output (i.e. the reading measured by the dial gauge). The mechanical vibration signal measured by TK-3E ranges from 50 to 254 μ M (2 to 10 mils) peak to peak.
