11 Typical measurement tasks
11.1 General
As a rule the parameters to be set up are dependent on the application. All
the parameters of an application are marked in the signal-flow chart.
The parameters that can be changed are correspondingly identified.
Some parameters are always set the same at our works. These parameters
are dealt with in the next chapter.
11.2 Works settings for the basic configurations
11.2.1 Absolute housing vibration according to DIN ISO 10816
Input sensitivity For vibration acceleration sensors 100 mV/g
For vibration velocity sensors
(e.g. VS-068/VS-069) 100 mV/mm/s
Measurement type RMS value of vibration velocity from 10 Hz to 1 kHz
Measurement range 0...20 mm/s RMS with a Crest Factor 5 (= 0 ... 100 mm/s input
range)
Averaging time 800 ms
Measurement
accuracy
< 0,75 % of measured value
(with analogue integration < 2,75 % of measured value)
plus 0,1 % of measurement range full-scale value
DC-output 4 ... 20 mA corresponding to 0 ... 20 mm/s RMS
Monitoring Alert alarm: Limit value 7.1 mm/s; relay delay time 1 s
Danger alarm: Limit value 11 mm/s; relay delay time 1 s
Relay output Alert alarm: Normally de-energized, non-self-latching
Danger alarm: Normally de-energized, non-self-latching
