How to use the acceleration sensor
This section explains how to connect the acceleration sensor with built-in preamplifier.
<Setting procedure>
•
Set the input items of the IEPE or IEPE-RMS.
•
Set "Sensor sensitivity in Misc" depending on the specifications of the sensor with sensor sensitivity.
•
Set the Range.
Refer to the range setting table [IEPE/IEPE-RMS Input]. Selection of the voltage sensitivity varies
depending on the range.
•
Charge module is used as a unit. Therefore, set depending on "Integral in Scaling" when processing either
the Velocity or Displacement.
•
The acceleration sensor can be set in the settings above. Simultaneously set the Range, Filter, Scaling, etc
for the measurement.
This section explains how to connect the charge-type acceleration sensor.
When other than the sensor with built-in amplifier is set, do not change the input setting to Built-in amplifier, Built-in
amplifier-RMS. This may damage the modules and the object to be measured.
<Setting procedure>
•
Set the input items of the Charge or Charge-RMS.
•
Set "Sensor sensitivity in Misc" depending on the specifications of the sensor with sensor sensitivity.
•
Set the Range.
Refer to the range setting table [Charge/Charge-RMS Input]. Selection of the charge sensitivity varies
depending on the range.
•
When the velocity or displacement is processed for the acceleration sensor, set the processing method in
"Scaling Iintegral".
•
When processing either the Velocity or Displacement for the acceleration sensor to be used, set the
processing method depending on "Integral in Scaling".
(11)-1-1 Input
Selects the input conditions
<Voltage module>, <High-speed voltage module>
Item select
Off Does not measure the input signal. Waveform, digital display also not carried out.
DC For use when measuring input signal.
<Voltage/Temperature module>
Item select
Off Does not measure the input signal. Waveform, digital display also not carried out.
DC For use when measuring voltage.
TEMP For use when measuring the temperature.
Humidity For use when using a B-530 humidity sensor to measure the humidity.
In this case, the voltage range is set to 1V, and EU settings cannot be set.
<Logic/Pulse module>
Item select
Off Does not measure the input signal. Waveform, digital display also not carried out.
Revolve Counts the number of pulses for each sample interval, and converts it to the rotation rate per minute.
Counts The pulse of each sample interval is calculated from the measurement start and is recorded.
Instant Records the number of pulses of each sample interval.
* Can be selected when set to pulse amplifier.
•
When sampling rate is external, rotation rate can not be changed, and will become an instantaneous value. However
the units will become RPM.
•
When using a pulse, it will be at 0 at first. When start trigger is off, the first point of data is 0.
