Сontrol and alarm system KSA-15

KSA-15 control and alarm system is a stationary system designed for continuous measurement and monitoring of vibration parameters on the rotating parts of the machine during its start-up and under load.

KSA-15 control and alarm system is used for measurement, control and alarm signaling in case of a permanent shift in performance characteristics, such as vibration displacement and axial shifting of rotors in centrifugal compressor units, beyond those specified.

KSA-15 is a measurement instrument registered in the State Register of Measuring Instruments of Ukraine under the number y424-95. It has a valid certificate of conformity number UA-MI/2p-3360-2010.

The system comes in six versions depending on the measurement range and the length of the body with an inductor.

Functions

  • measuring and displaying amplitude levels for vibration displacement on the dial test indicator​​;
  • measuring and displaying axial shift values on the dial test indicator​​​​;
  • alarm signaling (emergency and warning) in case the monitored parameters are beyond the threshold;
  • alarm signaling in case of the measuring channel failure;
  • analog output (voltage) for connecting devices and analyzers;
  • operating mode - continuous, round-the-clock.

KSA15 can be used independently, or as part of the aggregate or SCADA systems for process automation in oil and gas transportation, energy, mining and processing industries.
