產品標題: PR6423/10R-111 振動探頭
型號：PR6423/10R-111
品牌： 艾默生
詳情資料
工作原理：
渦流傳感器與前置器形成一個振蕩器，振幅隨著傳感器探頭與金屬被測物的接近而衰減，衰減的幅度與傳感器和被測物之間的距離成正比。出廠前已經使用校準材料42CrMo4對傳感器與前置器成套地進行了線性校準，因此安裝時不需要再做校準。用戶只需要調整傳感器和測量面之間的氣隙，直至從前置器的輸出得到所需信號。
轉速監測: PR9376+RSMO10(RSMO20/RSMO40)，帶保護2.5.2軸向位移: PR6424+CO+SDM010/S1，帶保護2.5.3脹差: PR6426+CO+SDM010/S12.5.4 軸振動:PR6423+CON021+VBM010/MMS6110 垂直軸振
軸承振動(垂直方向): PR9268+VBMO30/MMS6120(瓦振採用MMS6120，雙通道: 瓦振採用 VBMO30，單通道)。
偏心:PR6423+CON021+SEM010,由RSM010鍵相通道(2 通道)提供鍵相信號。
採用MMS6000係列產品測量汽輪機轉速、軸向位移、脹差、軸振動、軸承振動、偏心，具體配置如下:2.6.1 轉速測量、監測:PR9376+MMS6312，帶保護2.6.2軸向位移:PR6424+CO+MMS6210，帶保護2.6.3脹差:PR6426+CO+MMS62102.6.4軸振動:PR6423+CO+MMS6110。目前，瓦振、軸振採用串、並聯的方式實現振動大停機保護。

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.
