МК32, Control module
Description
Universal 4-channel module for measurement absolute and relative vibration with graphical indicator, designed for measurement of parameters represented by static or dynamic current or voltage signals.
Its distinctive features are a large set of computational functions, which makes the module optimal for monitoring vibration parameters of absolute and relative vibration channels.
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
- Set of additional functions for measurement channels
- Redundant digital communication interfaces
- Redundant synchronization lines
- Configurable frequency bands
- Tachometer reference pulse repetition capability.
Functions:
- Measurement of vibration parameters
- Calculation of RMS vibration velocity and peak-to-peak vibration displacement
- Calculation of parameters based on 1X components
- Sensor health check
- Transmission via a unified current output
- Transmission via digital communication interfaces
- Setpoint trip verification
- Calculation of eccentricity based on 1X components
- Sensor signal linearization
