With four U8552 VOLTAGE/TEMP Units and seven LR8532 WIRELESS
VOLTAGE/TEMP Units, you can measure a total of 330 channels.
Plug-in unit and Wireless unit in mix will allow you to build a measurement system that suits your needs.
If wireless units are used with other units (wireless or plug-in), the sampling-timing shift between the units is peri-
odically corrected.*
In addition, at times the wireless communication is cut off, the correction function works after the communication is
restored and the sampling-timing shift between the units is corrected.
* Even in good wireless communication conditions (low interference) the sampling-timing between devices may shift about 20 ms.
In bad wireless conditions, the sampling-timing shift will be much worse than this.

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-
ricing noise resistance.
(ex.) Sampling rate : 1 s
Number of channels Cutoff frequency

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)

Strain measurement
Measure strain with a 1 ms sampling rate
Connect strain gages directly and measure at a sampling rate of up to 1
ms. Strain gages tend to have long, thin wires that are easily broken, but
that potential pitfall can be avoided by using wireless units so that wire
length is minimized.
Connect strain gages directly
The Strain Unit has a built-in bridge box, allowing you to connect strain gages directly to
its input terminals.

STRAIN UNIT U8554 WIRELESS STRAIN UNIT LR8534
Previous models were incapable of measuring temperature accurately in noisy environments due to the inuence of high frequencies, which
caused values to shift or uctuate signicantly. The LR8450 uses a revamped design to dramatically reduce the inuence of high-frequency noise.
Example: Measure temperature by connecting the tip of a K thermocouple to the screw on an inverter’s PWM output terminal (W-phase)
when using the Voltage/Temp Unit U8550 (settings: 100 ms sampling in the 100°C f.s. range).

Work time can be reduced using the LR8450-01 and wireless units, since only minimal wiring is required. If the measurement target is
located in a lab, this approach eliminates the need for wiring and avoids having to drill holes in the walls of the monitoring room where
data is being checked.

acquiring integrated power or ow rate.
The LR8450/LR8450-01 provides two output terminals for volt-
ages, each of which can supply 100 mA current, eliminating the
need for a separate sensor power supply. You can select 5 V,
12 V, or 24 V from the VOUTPUT1 terminal and 5 V or 12 V from
the VOUTPUT2 terminal.

Example: Recording 30 analog channel with 2 units (no alarm output or waveform processing)
Because the header portion of waveform les is not included in capacity calculations, expected actual maximum time is about 90% of those in the tables.
The maximum recording time varies with the number of measurement channels. Recording times are doubled if the number of measurement chan-
nels shown in the table is halved.
