ВМ22, Control unit
Description
Universal 4-channel module for measuring of linear displacements, rotational speed and eccentricity with a graphic display, 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 the parameters of displacement, eccentricity (bend) or rotational speed (phase) channels.
It is built on base MK22 control module in a standalone-mount enclosure powered from a 230 VAC mains supply.
Key features:
- Data indication via a liquid crystal display (LCD)
- Standalone-mount
- 230 VAC mains supply
- Standard processing speed (up to 100 ms)
- Redundant digital communication interfaces
- Open collector/Relay output.
Functions:
- Measurement of static or dynamic current or voltage signals
- Sensor health monitoring
- Transmission via a standard current output
- Transmission via digital communication interfaces
- Setpoint trip monitoring
- Tachometer pulse repetition
