EMERSON MMS6120 module

Product Overview:

MMS6120 is a dual channel bearing vibration monitor launched by Emerson's German EPRO brand, commonly used for vibration of rotating machinery

Continuous monitoring and protection of displacement or velocity signals. This module has a compact structure and stable performance, and is widely used in the status monitoring system of key equipment such as steam turbines, compressors, pumps, and fans.

Main features and advantages

Dual channel monitoring: Two sets of vibration or displacement sensors can be connected simultaneously, supporting parallel analysis and improving monitoring efficiency.

Industrial grade accuracy: using 16 bit ADC, high measurement accuracy, good repeatability, suitable for micrometer level vibration detection.

Broadband response: The frequency range covers 0.5 Hz-10 kHz, taking into account both low-frequency shaft vibration and high-frequency bearing fault characteristics.

Multiple outputs: Provides 4-20 mA, 0-10 V, relay alarm, and Modbus/PROFIBUS-DP communication interface for easy access to DCS or PLC.

On site programmability: Parameter settings such as range, alarm points, and filters can be completed through the front panel buttons or software tools without the need for disassembly.

Durable and sturdy: Modular aluminum shell design, resistant to vibration and impact, working temperature -20 ° C...+70 ° C, suitable for complex industrial environments.
