K2+ - Vibration Controller - IMV CORPORATION



Case Study

Vibration Controller



The latest vibration controller with enhanced usability and test performance in addition to improved network functions.

The K2+ is the latest vibration controller that has further evolved the usability and test performance of the K2. Network functions have also been enhanced, making it easier to connect to various devices, including personal computers. In addition, it has compatibility with the previous model, the K2, and test definitions from the K2 can be used within the K2+. All K2+ hardware and software are developed in-house, and we constantly strive to improve them whilst incorporating the latest technology and customer feedback.



■Ethernet connectivity
The K2+ uses Ethernet, so installation is easy and a laptop can be used for operation. IMV secures your tests' data accuracy, providing a solution that reduces the risks of using long cables. The conditioner is as close to the sensor as possible. You can also easily control K2+ applications from your own software using simple XML commands*.
*The TCP/IP server option is required.
■User-friendly interface

Easily recognized icons are used for file management.

■Built-in analog front end (charge amplifier, etc.)
With the built-in charge amplifier, IEPE (ICP) power supply and TEDS connectivity, there is no need for an external signal conditioner. Any type of accelerometer can be connected to the K2+ vibration controller directly.
■Parallel monitor terminal

The parallel terminals allow easy connection of additional measurement equipment, for example to record time and date or to evaluate test data within dedicated hardware and software for the specimen under test. For sensitive applications such as satellite testing, your time domain can then back up data for post processing.

■High control capability
Precision on-chip 32 bit ADCs and DACs ensure excellent control accuracy over a wide dynamic range.
■Web monitor

The user can monitor vibration tests remotely by connecting over the Internet.

■Safety interlock function
A hardware mute function operating independently of software provides complete protection for the vibration system and payload.
■Email notification
Remote sites can be notified by email of any abnormality during testing or termination of a test.
Test definitions and results are output from the K2+ in CSV format.

Common optional software Outline
Analogue waveform
signal data program

Provides analogue waveform signal capture. Saved data can then be used as a reference for
SHOCK, BMAC waveform controls or Random vibration PSD control.

• Sampling Frequency 51.2 kHz maximum
• Data Length Maximum 5,000 k 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.
Integrated Control System Integrated vibration and climatic chamber controls for combined testing.
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.

Test standards

A test file is automatically generated upon selection of the test conditions defined by test standards. Minimizing control error is key for a good vibration control system, and for this reason we have included major vibration standards in the K2+ Quick Launcher software option. This will prevent the operator from accidentally choosing the wrong profile.
*Please refer to the following for the test standards.
