4.3 Summary of parameters for signal filtering

Note:

In the user menu of the User _Terminal the supplementary parameters

are not displayed. The actual construction steps of each signal path

can respectively be taken from the individual instrument docu-

mentation (signal-flow chart).

4.3.1 Analogue signal integration

♦ All highpass filters can be selectively combined with an analogue signal

integration. The use of these filters is only possible in combination with

single channels for acceleration sensors (Acceleration Interface Module

= input modules A-TIM-CCS & A-TIM-24 V). The original signal from the

acceleration sensor is converted to a vibration velocity signal. The

activation is done by selecting the corresponding measurement unit,

e.g.: mm/s in the configuration of the A-TIM module.

♦ The highpass filter according to DIN ISO, in combination with accele-

ration sensors, is coupled with an analogue signal integration as

standard.

♦ Should the analogue signal integration be used in a signal path, this will

be identified in the signal-flow chart of the instrument.

4.3.2 Frequency response linearisation

♦ All highpass filters can selectively be used in combination with

frequency response linearisation. The use of this filter is limited to the

use with single channels for vibration velocity sensors (Velocity Sensor

Interface Module = V-TIM). The frequency range is extended toward the

lower frequencies.

♦ The highpass filter according to DIN ISO, in combination with vibration

velocity sensors is combined as standard with frequency response

linearisation.

♦ There are two forms of frequency response linearisation:

◊ for VS-068/VS-069 (Brüel & Kjær Vibro sensors):

8 Hz rectification in combination with input module V-TIM -8 Hz

◊ for VS-077/VS-079 (Brüel & Kjær Vibro sensors):

15 Hz rectification in combination with input module V-TIM -15 Hz

♦ Should the frequency response linearisation be used in a signal path,

this will be identified in the signal-flow chart of the instrument.
