工作原理：

涡流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而衰减，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。

转速监测: PR9376+RSMO10(RSMO20/RSMO40)，带保护2.5.2轴向位移: PR6424+CO+SDM010/S1，带保护2.5.3胀差: PR6426+CO+SDM010/S12.5.4 轴振动:PR6423+CON021+VBM010/MMS6110 垂直轴振

轴承振动(垂直方向): PR9268+VBMO30/MMS6120(瓦振采用MMS6120，双通道:  瓦振采用 VBMO30，单通道)。

偏心:PR6423+CON021+SEM010,由RSM010键相通道(2 通道)提供键相信号。

采用MMS6000系列产品测量汽轮机转速、轴向位移、胀差、轴振动、轴承振动、偏心，具体配置如下:2.6.1 转速测量、监测:PR9376+MMS6312，带保护2.6.2轴向位移:PR6424+CO+MMS6210，带保护2.6.3胀差:PR6426+CO+MMS62102.6.4轴振动:PR6423+CO+MMS6110。目前，瓦振、轴振采用串、并联的方式实现振动大停机保护。

Working principle:

The eddy current sensor and the preamplifier form an oscillator, and the amplitude decays as the sensor probe approaches the metal object being measured. The amplitude of the attenuation is proportional to the distance between the sensor and the object being measured. Before leaving the factory, the calibration material 42CrMo4 has been used to perform a complete linear calibration of the sensor and proximitor, so there is no need for further calibration 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 front mount.

Speed monitoring: PR9376+RSMO10 (RSMO20/RSMO40), with protection 2.5.2 Axial displacement: PR6424+CO+SDM010/S1, with protection 2.5.3 Differential expansion: PR6426+CO+SDM010/S12.5.4 Shaft vibration: PR6423+CON021+VBM010/MMS6110 Vertical shaft vibration

Bearing vibration (vertical direction): PR9268+VBMO30/MMS6120 (bearing vibration adopts MMS6120, dual channel: bearing vibration adopts VBMO30, single channel).

Eccentricity: PR6423+CON021+SEM010, keyed signal provided by RSM010 keyphasor channel (2 channels).

The MMS6000 series products are used to measure the turbine speed, axial displacement, differential expansion, shaft vibration, bearing vibration, and eccentricity. The specific configuration is as follows: 2.6.1 Speed measurement and monitoring: PR9376+MMS6312, with protection. 2.6.2 Axial displacement: PR6424+CO+MMS6210, with protection. 2.6.3 Differential expansion: PR6426+CO+MMS6210. 2.6.4 Shaft vibration: PR6423+CO+MMS6110. At present, the vibration of bearings and shafts is achieved through series and parallel connection to achieve vibration shutdown protection.
