-----------------------------------------------------------------------------------------------------------------------------------------------------------------

分析
選擇測量類型(從簡單的振動總量值到FFT和時域波形,再到電渦流傳感器的更高級測量,如軸心軌跡),
根據您的要求設置測量參數(頻率範圍,取樣,單位等)並同步蒐集所有預定義的測量模式。

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

路徑  
路徑功能用於工廠設備的日常巡檢及數據收集。只需在DDS軟件中建立帶有測量點位置的路徑樹(也可以在免費的DDS版本中),
並定期進行測量。將蒐集的數據傳輸到DDS軟件以觀察趨勢並分析數據。

-----------------------------------------------------------------------------------------------------------------------------------------------------------------


啟動分析
與分析模式類似,可以在其中設置任何您需要的測量參數。同時也能夠允許您控制數據的保存方式,例如盡快、或根據速度變化、時間變化等。

-----------------------------------------------------------------------------------------------------------------------------------------------------------------


紀錄分析
特有的測量模式用於變化的工況以及無法預測的狀況。紀錄器功能用來“記錄”來自傳感器的原始信號,表示來自設備的原始信號。
這允許稍後在PC上對信號進行後處理。您可以反複播放此記錄並對其應用任何測量設置。

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

動平衡
動平衡功能允許您執行旋轉部件的單面或雙面平衡工作,例如工業風機,鼓風機,主軸等。

-----------------------------------------------------------------------------------------------------------------------------------------------------------------


FASIT  (  專家系統 ) 
FASIT(故障根源識別工具)是一種自動檢測設備故障的專家系統:
- 不平衡
- 錯位
- 鬆動
- 軸承故障

------------------------------------------------------------------------------------------------------------------------------------------------------------------

聽診器
不要再使用螺絲刀來聽取軸承噪音。將傳感器放在軸承座上,並用耳機收聽機器/軸承噪音。
VA4 Pro可以監聽4個頻道的信號。只需在各個頻道之間切換。根據需要調節音量。

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

LUBRI ( 潤滑監測 ) 
Lubri是一種用於監控和控制潤滑過程的維護應用功能。Lubri測量實際軸承潤滑狀態,並在潤滑狀態最佳時通知操作員。

-----------------------------------------------------------------------------------------------------------------------------------------------------------------


倍頻程分析
倍頻程分析允許您測量可聽聲音。連接ICP麥克風並測量聲級和倍頻譜,可選擇1/1, 1/3,1/12, 1/24分辨率。

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

碰撞测试
測量結構共振頻率的簡便方法。無需任何設置,只需將傳感器放在結構上並用適當的錘子敲擊即可。

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

ADS(結構變形分析)
ADS - 結構變形軟體基於運行時形狀變化的方法。這意味著我們通過動畫可看見設備的振動。
在動畫當中,振動運動減慢到非常低的頻率,並且運動的幅度增加,因此我們可以看到振動。
您可以直接在VA4 Pro設備上模擬設備運動的動畫!

-----------------------------------------------------------------------------------------------------------------------------------------------------------------


超音波分析
測量人耳無法聽到的聲音- 超音波。典型應用是洩露檢測、電弧或早期軸承故障檢測。

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Analyzer
Select the type of the measurement (from simple overall values through FFTs and time signals to more advanced measurements with Proximity probes such as Orbits), set up the measurement settings according to your requirements (frequency range, sampling, units etc.) and take all the predefined measurements simultaneously.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Route
Route module is used for day to day data collection of your factory machinery. Simply create your route tree with measurement points location in DDS software and take the measurements regularly. Transfer collected data to DDS software to watch the trends and analyze the data.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------


Run Up
Similar to Analyzer mode where you can setup any measurement which you like. RunUp allows you to control the saving of data for example as soon as possible, or by speed change, time change etc.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------


Recorder

Unique measurement mode with unappreciated value. Recorder “records” the raw signal from the sensor, means raw signal from the machine. This allows to make a post processing of the signal later on your PC. You can play this record again and again and apply any measurement setting to it.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

BALANCER

Balancer allows you to perform one or two plane balancing job of rotating parts such as industrial fans, blowers, spindles etc.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------


FASIT - Expert system

FASIT (Fault Source Identification Tool) is an expert system for automatic detection of possible machine faults:
- Unbalance
- Misalignment
- Looseness

------------------------------------------------------------------------------------------------------------------------------------------------------------------

Stethoscope
Do not use a screw driver to listen your bearing noise anymore. Place the sensor on the bearing house and listen the machine / bearing noise in headphones. VA4 Pro enables to listen signals from 4 channels. Just switch between individual channels. Adjust the volume according to your needs.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Lubri
Lubri is a maintenance tool used for monitoring and control of the lubrication process. Lubri measures the actual bearing lubrication status and informs the operator when the lubrication state is optimal.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------


Octave analysis
Octave analysis allows you to measure hearable sound. Connect your ICP microphone and measure sound level and Octave spectrum with selectable 1/1, 1/3, 1/12, 1/24 resolution.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

BUMP test
Easy way how to measure structure resonance frequencies. No need of any settings, just place the sensor on the structure and hit it with appropriate hammer.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

ADS
ADS - Animated deflection shapes software is based on the method of operating deflection shapes. This means we visualize the vibrations of certain machine by animation. During the animation the vibration movement is slowed down to very low frequency and the amplitude of the motion is increased so we can see the vibration. You can animate the machine motion directly on the VA4 Pro device!

-----------------------------------------------------------------------------------------------------------------------------------------------------------------
