Instrument Overview and Features

The LR8450/LR8450-01 is a multichannel logger that can measure physical quantities like temperature, voltage, and strain and observe data on CAN buses when combined with various measurement modules.

Two categories of measurement modules are available: plug-in modules that can be plugged directly into the instrument and wireless modules that can send data wirelessly.

Choose the modules that are right for your application from 16 different types.

The LR8450 can accommodate plug-in modules.

The LR8450-01 is capable of communications with not only plug-in modules but also wireless modules.

Plug-in modules and Wireless modules

Add or remove modules according to the number of channels.

Both the LR8450 and LR8450-01 can accommodate up to four plug-in modules.

The LR8450-01 can also record data using only wireless modules, even if no plug-in modules have been installed.

The LR8450 can accommodate up to four CAN Units (plug-in) and the LR8450-01 can accommodate up to four CAN Units (total of plug-in and wireless modules).

Connecting Plug-in Modules

Maintain the sampling speed, even when modules are added.

Adding modules, each of which incorporates an A/D converter, does not cause the reduction of the sampling speed.

You can perform measurement at different data refresh rates (sampling intervals) appropriate for every module.

“Measurement module data refresh intervals” in the Instruction Manual.

Setting example

  • Control signals are recorded at a high sampling interval of 1 ms using the U8553 High Speed Voltage Unit.

  • Multi channels of temperatures are recorded at a sampling interval of 1 s using the U8552 Voltage/Temp Unit.
    (The U8552 can use a relatively low sampling speed, allowing the filter to set a lower notch frequency. Using the U8552 can eliminate lower-frequency noise.)

Perform strain measurement.

You can measure multiple channels of strain data using the Strain Unit.

The instrument has a built-in bridge box, allowing it to support a variety of connection methods.
