measurement
Voltage measurement
Measure outputs from a pressure sensor and
other sensors at 1 ms max. sampling rate.
1 ms sampling is very suitable to record outputs of several tens of Hertz from pressure
sensors and vibration sensors.
Road test automobiles
Since increasing the number of units has
no effect on the cutoff frequency, which
changes with the sampling rate, power
supply noise can be reduced without sac-
ricing noise resistance.

Each unit incorporates its own A/D con-
verter. This design keeps the maximum
sampling rate high even when units are
added.
Example 1: Use four U8553 High Speed
Voltage Units (with 5 channels each) to
measure 20 channels at a sampling rate
of 1 ms.
Example 2: Use four U8550 Voltage/
Temp Units (with 15 channels each) to
sample 60 channels at a sampling rate of
10 ms.
The cutoff frequency, which varies with the data
refresh interval, can be set separately for each
unit. You can use long data refresh intervals,
which boost lter effectiveness, and short data re-
fresh intervals for different units at the same time.
• Measure control signals at maximum speed: Unit 1
(data refresh interval: 1 ms)
• Measure battery voltage uctuations: Unit 2
(data refresh interval: 1 ms)
• Measure temperature using thermocouples: Unit 3
(data refresh interval: 1 s) with strong lter
