MK11, Control module
Description
2-channel rotor axial displacement measurement module with a graphical indicator, designed for measuring parameters represented by DC current or voltage signals via two independent measurement channels.
Its distinctive features are a high measurement speed (50 ms) and the ability to be powered from a 50 Hz, 220 V AC mains, which makes the module optimal for monitoring rotor axial displacement channel parameters.
The module is equipped with standard 4-20 mA current outputs, logic outputs, and digital interfaces CAN 2.0B and RS485.
Key features:
- Data indication via a liquid crystal display (LCD)
- Mounting in a Vibrobit 300 instrumentation section
- Increased processing speed (up to 50 ms)
- Redundant digital communication interfaces
- Capability of being powered from a DC or AC source
- Simplified calibration procedure
Functions:
- DC signal level measurement
- Sensor health monitoring
- Transmission via a standard current output
- Transmission via digital communication interfaces
- Setpoint trip monitoring
