Description
Metso MBMT120 control board
MBMT120 is a general-purpose eddy current sensor preamplifier.
1.Core Functions and Operating Principles
Power Supply and Drive: The MBMT120 provides a high-frequency oscillating current to the connected eddy-current probe.
Signal Detection: Changes in the gap between the probe and the metal object under test, as sensed by the probe, cause changes in the impedance of the probe coil.
2.Key Features and Benefits
Wide Frequency Response: With a frequency response up to 10 kHz, it accurately captures the rapid vibrations of high-speed rotating machinery.
High Accuracy and Linearity: Provides excellent measurement accuracy and good linearity, ensuring reliable data.
Temperature Stability: Built-in temperature compensation minimizes the impact of ambient temperature changes on measurement accuracy.
Standard Output: The industry-standard -2V to -18V output range is recognized by most DCS, PLCs, and dedicated monitoring systems.
3. Technical Specifications (Summary)
Supply Voltage: Typically -18 VDC to -24 VDC.
Output Signal: -2 VDC to -18 VDC (linear across the entire measurement range).
Frequency Response: 0 to 10,000 Hz (10 kHz).
Operating Temperature: Typically -40°C to +85°C, suitable for most industrial environments.
Physical Mounting: Designed for mounting on a standard DIN rail.
4. Main Applications
The MBMT120 proximitor is widely used for condition monitoring and protection of various large, critical rotating machinery. Key parameters measured include:
Shaft eccentricity
Key phase (requires use with a key phase sensor module)
Differential expansion (requires special probe specifications and setup)
Application industries: Oil and gas, power generation (thermal, nuclear, and hydropower), chemicals, metallurgy, and papermaking.
