Vibration Controller

K2

K2

Common hardware supports all types of vibration test.
The K2 controller provides the precision and repeatability required to test with condence during both product development and series production.
The K2 hardware and software has been developed in-house, giving IMV full design control of this important part of a vibration system.
The K2 system offers enhanced functions and operability based on the most advanced technologies and incorporating feedback from our customers.

Features

■User-friendly interface

Instinctive Operation

[Intuitive operation]

Easily-recognised icons are used for file management.

Simplified definition

[Short-cut operations]

The key operations are initiated using a simplified set of commands.

Scheduler

[Scheduler]

Define the test schedule and execute it in order.

■Easy-to-use functions

Web monitor

[Web monitor]

A user can monitor a vibration test remotely by connecting over the internet.

Report generator

[Report generator]

Results can be exported to Microsoft Word in a range of customised formats.

■Precision control capabilities
K2 employs high-resolution 24-bit A/D and D/A converters to achieve high-precision, repeatable control.
■Safety interlock function
A hardware mute function operating independently of software provides complete protection for the vibration system and payload.
■E-mail notification
Remote sites can be notified by email of any abnormality during testing or termination of a test.
■DataViewer
Software to display result data file saved after the test of SINE, RANDOM and SHOCK.

Software

Common optional software Outline
CAPTURE:
Analogue waveform
signal data program

Provides analogue waveform signal capture, saved data can then be used as the reference of
SHOCK, BMAC waveform controls or Random vibration PSD control.

• Sampling Frequency 51.2kHz maximum
• Data Length Maximum 5000k points
• Input Channel Maximum 64
• Waveform edit/analysis function Filtering, Frequency transfer processing, PSD transfer,
Transmissibility ratio between channels
SCHEDULER:Test scheduler Pre-defined tests can be executed in sequence.
TCP Communication Server TCP communication server software that allows external applications to operate K2 applications and acquire vibration data and operating status by sending and receiving commands via TCP / IP.
