MMS6120 is a two-channel bearing vibration measurement module

German EPRO MMS6120 dual channel tile vibration measurement module MMS6120 Features:

Dual channel tile sensor module to monitor bearing vibration.

Can be replaced in operation, can be used alone, redundant power input.

Extended self-check function, built-in sensor self-check function, password protection operation level. For eddy current sensor PR9266/... And PR9268/... Or piezoelectric sensors. RS232/485 port for field configuration and communication, can read the measured value. Built-in linearization processor.

Record and store measurement data of the last start/stop. Applications:

Dual channel bearing vibration measurement module MMS6120, measuring bearing vibration with electric speed sensor, sensor output types are:

VRMS (Veff) root mean square Vibration velocity Sop (Zero peak) Vibration displacement

Spp(peak-to-peak value) vibration displacement

Modules are designed to meet common international standards such as API670, VDI2056, VDI2059. Measurements of this module can be combined with measurements of other modules to form turbomachinery protection systems and as inputs to analytical diagnostic systems, fieldbus systems, decentralized control systems, power plant/main computers, networks such as WAN/LAN networks, and Ethernet.

For steam engines, gas engines, water turbines, compressors, fans, centrifuges and other turbo-machinery, the use of this system can improve the efficiency, operation safety and prolong the service life of the machinery. The MMS6120 is a two-channel bearing vibration measurement module that can measure bearing vibration (vibration) with a dynamic speed sensor to monitor and protect various types of turbine-machinery, such as steam turbines, gas turbines, compressors, fans, gearboxes, blowers, centrifuges, etc.

The output signal of the sensor mounted on the bearing is proportional to the maximum vibration of the bearing. The MMS6120 module converts the sensor input signals of the two channels into the standard signal output. Other parts of the module provide alarm, sensor power supply, module power supply, channel and sensor detection and signal filtering functions.

The module has a built-in microprocessor, which can set the working mode and parameters through the field portable computer or the remote communication bus, read all the measured values, and perform spectrum analysis. The last start up/stop procedure is stored in the module and can be displayed through the computer.

1. Signal input

The MMS6120 has two independent electric speed sensor inputs - SENS 1H (z8)/SENS1L (z10) and SENS 2H (d8)/SENS 2L (d10). The matching speed sensor is the PR926X series electrodynamic sensor produced by epro, Germany, with an input voltage range of -5... +15V dc.

The module provides each sensor with a 0... An 8mA lifting coil current compensates for mechanical settling of the sensor coil, which is available in configurations SENS1 +(z6)/SENS1- (b6) and SENS 2+(d6)/SENS 2- (b8).

Sensor signals can be detected at the SMB interface on the front panel of the module.

In addition, the module also has a key signal input (must be greater than 13V), which is necessary for speed control mode and spectrum analysis. 2 Signal output

a. Eigenvalue output

The module has two current outputs representing characteristic values :l1+(z18)/ l1-(b18) and l2+(z20)/ 12-(b20), which can be set to... A 20mA or.20mA module has two 0's representing the characteristic value... 10 V voltage output EO 1 (d14) /EO 2 (d16).

b. Dynamic signal output

Module provides two 0... 20 Vpp dynamic signal output AC1(z14)/AC2 (z16) for spectrum analysis. 0... 20 Vpp corresponds to the range of eigenvalues.
