МК22, Control module
Description
Universal 4-channel module for measurement of linear displacements, rotor speed and eccentricity with a graphic display, 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 parameters of displacement, bow (eccentricity) or rotor speed (phase) 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
- Standard processing speed (up to 100 ms)
- Redundant digital communication interfaces
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
