MMS6120 Dual channel bearing vibration measurement module

Measurement function:
Dual channel measurement: It can simultaneously monitor the vibration of bearings in two channels, suitable for various types of turbomachinery such as steam turbines, gas turbines, compressors, fans, gearboxes, blowers, centrifuges, etc.
Multiple measurement modes: capable of measuring bearing vibration in horizontal, vertical, or axial directions, and supporting multiple output types such as root mean square value of vibration velocity (VRMS), zero peak value (SOP) vibration displacement, peak to peak value (SPP) vibration displacement, etc., to meet different measurement needs.
Wide frequency range: The frequency range is usually 10-1000Hz (refer to VDI12056/DIN45666/ISO3945), and there are also other optional frequency ranges such as 5/10-50-1000/1600Hz, which can accurately measure vibration signals at different frequencies.
Signal processing and output:
Built in linearization processor: processes input sensor signals to improve measurement accuracy and stability.
Rich output interfaces: with two independent current outputs (0/4-20mA), configurable, open circuit and short circuit protection, allowing loads less than 500 Ω; Two independent voltage outputs (0-+10V), open circuit and short circuit protection, with a load impedance greater than 10k Ω; There are also two independent AC component voltage outputs (0-20Vpp) for spectrum analysis, with a frequency range of 0.1Hz-5kHz (± 20%/-3dB).
Sensor related characteristics:
Sensor adaptability: It is compatible with electric speed sensors such as PR9266/… and PR9268/… produced by EPRO company. The input voltage range of the sensor is -5V to+15VDC, and the input impedance is greater than 100k Ω.
Boosting coil current: The module provides an independent buffered boosting coil current output for each sensor to compensate for mechanical settling of the sensor coil. The current range is 0-8mA and can be set in the configuration with a step size of 40 μ A.
Other features:
Can be replaced during operation: supports hot swapping function, facilitates module maintenance and replacement without shutting down the system, reduces equipment downtime, and improves production efficiency.
Extended self checking function: Built in sensor self checking function and module monitoring circuit can continuously monitor whether the sensor signal is within the preset range, whether the connection cable between the sensor and the module is normal, whether the system power supply voltage is stable, whether the configuration and parameter settings are correct, and whether the internal temperature is overloaded, ensuring the reliability and stability of the system.
Communication function: Equipped with RS232/485 ports for on-site configuration and communication, it can read measurement values, making it convenient for users to set module parameters and read data.
Data storage function: capable of recording and storing the most recent start/stop measurement data, providing data support for equipment fault diagnosis and analysis.

ABB, the world’s leading power and automation technology group, announced that it will provide a 363 kV high-voltage isolated circuit breaker with an all fiber current transformer for the Shaanxi Fuping Intelligent Substation. This circuit breaker combines three substation functions: isolation, circuit breaking, and current measurement, reducing the substation’s footprint by up to 70%. At the same time, it is also the world’s first isolated circuit breaker equipped with fiber optic current transformers at this high voltage level.

All fiber current transformers will replace traditional current transformers used for measurement and protection in integrated intelligent switches, and create conditions for grid automation. In the northwest region of China, the voltage level of 363 kV is the most common. This application is also the first commercial application of the isolated circuit breaker technology at this voltage level.

As part of the new generation intelligent substation project planned by State Grid Corporation of China in 2015, Shaanxi Fuping Intelligent Substation will provide electricity for the rapidly developing industrial belt around Fuping County, Shaanxi Province. The project aims to utilize the most advanced technology to enable remote control, protection, automation, monitoring, and analysis of substations, while reducing operating costs, footprint, and environmental impact. At the same time, the new generation of smart substations can make the national power grid more efficient, flexible, and reliable, laying the foundation for China’s increasing integration of renewable energy into the grid. According to data from the National Energy Administration of China, the cumulative installed capacity of renewable energy generation in China exceeded 400 million kilowatts in 2014, accounting for over 30% of the total installed capacity of electricity, continuing to maintain its position as the world’s largest country in terms of renewable energy utilization scale.

ABB has been providing the most advanced technology for China’s power infrastructure construction, supporting a stronger, smarter, and greener power grid through our equipment. This once again demonstrates that leading technology will be the key to ABB’s market leadership position under the ‘new stage’ strategy, “said Yuker, President of ABB’s Power Products Business

As a pioneer in isolated circuit breaker technology, ABB has installed approximately 1800 isolated circuit breakers worldwide. Since 2010, ABB has been operating a test project in Sweden for 420 kV high-voltage isolated circuit breakers equipped with all fiber current transformers, accumulating a wealth of experience in this field. This innovative technology not only integrates three types of substation functions, but also provides digital output of substation and grid automation related data, and is fully integrated into the smart grid based on the latest IEC digital communication standard (IEC 61850-9-2LE).

This technology can replace traditional switchgear and reduce the footprint of air isolation switches in substations by 70%. Not only that, it can also help high-voltage substations reduce several tons of equipment, improve substation safety, reduce installation time, save design, operation, and maintenance costs, and reduce environmental impact.

By the end of 2015, State Grid Corporation of China plans to build a new round of 50 next-generation smart substations and vigorously promote the construction of smart grids. ABB will provide innovative high-voltage isolation circuit breakers equipped with full fiber current transformers, intelligent medium voltage switchgear, and transformer intelligent electronic components (such as innovative self drying respirators) for 13 of the smart substations, helping to create a more efficient and reliable smart grid and achieve the “interconnection of goods, services, and people”.
