ВМ32, Control unit
Description
Universal 4-channel unit for measuring absolute and relative vibration with graphic indicator, designed to measure parameters represented by static or dynamic current or voltage signals.
Its distinctive features include a large set of computational functions, which makes the module optimal for monitoring vibration parameters of absolute and relative vibration.
It is built on base MK23 control module in a standalone-mount enclosure powered from a 230 VAC mains supply.
The presence of relay-type discrete outputs and the number of OC outputs depend on the unit's version.
Key features:
- Standalone-mount
- Data indication via a liquid crystal display (LCD)
- 230 VAC mains supply
- Set of additional functions for measurement channels
- Redundant digital communication interfaces
- Redundant synchronization lines
- Configurable frequency bands
- Tachometer reference pulse repetition capability
- Open collector/Relay output
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
