PR6424/003-030+CON021 EPRO 前置器

PR6424/003-030+CON021 EPRO  前置器

可测量下列物理量：

- 旋转部分和固定部分之间的间隙

- 轴的振动和偏心

- 轴的径向及轴向位移

- 轴瓦的磨损

- 油膜的厚度

- 轴与轴承的相对热膨胀

- 轴承的热膨胀

- 阀门的位置

工作原理：

涡轮传感器与前置器形成一个振荡器，振幅随着传感器探头与金属被测物的接近与衰减，衰减的幅度与传感器和被测物之间的距离成正比。出厂前已经使用校准材料42CrMo4对传感器与前置器成套地进行了线性校准，因此安装时不需要再做校准。用户只需要调整传感器和测量面之间的气隙，直至从前置器的输出得到所需信号。

The following physical quantities can be measured:

- The gap between the rotating part and the fixed part

- Shaft vibration and eccentricity

- Radial and axial displacement of the shaft

- Bearing wear

- Thickness of oil film

- Relative thermal expansion of shaft and bearing

- Thermal expansion of bearings

- Valve position

How it works:

The turbine sensor and the preprocessor form an oscillator, and the amplitude of the attenuation is proportional to the distance between the sensor and the measured object as the sensor probe approaches and attenuates. The sensor and preprocessor have been linearly calibrated in complete sets using calibration material 42CrMo4 before delivery, so no calibration is required during installation. The user only needs to adjust the air gap between the sensor and the measuring surface until the desired signal is obtained from the output of the preprocessor.
