MEMORY HiLOGGER LR8450-01 (Wireless LAN model)

1ms Sampling Portable Logger Expandable to 330 Channels with Your Choice of Plug-in or Wireless Input Modules

Hioki Memory HiLoggers are high-speed data loggers for recording multiple channels of voltage, temperature, resistance or humidity signals, some models providing complete isolation between channels and strong noise resistance.
The LR8450-01 offers a sampling speed of up to 1 ms and up to 330 channels, depending on the types of plug-in or wireless modules that are selected. Collect data from wireless modules installed in remote or confined locations via a LAN connection. New input modules measure strain and distortion, ideal for automotive applications involving the evaluation of vehicle components as well as robotic equipment.

Actual measurement example using CAN UNIT

This video shows how the MEMORY HiLOGGER LR8450-01 and CAN UNIT are used to measure the temperature of an actual vehicle. The analog data measuring the temperature inside the vehicle and the CAN data are simultaneously displayed on the waveform in real time. You can also see how the measured analog data is output as CAN signals in real time.

Wireless units can be easily registered in 2 steps!

Memory HiLogger LR8450-01 is a data logger equipped with wireless LAN.
It is ideal for collecting data in dispersed locations and locations where wiring is difficult.
You can add up to 7 wireless modules and measure up to 330 channels.
Will introduce to you two easy steps, to register the wireless modules onto the main instrument.

Key Features

  • Wireless LAN model expandable to 330 ch with wireless and plug-in modules

Measurement of Leakage Current in EV Power Management

In the domain of e-mobility, especially electric vehicles (EV), range extension is one of the most important priorities. To boost range, it’s important to measure power consumption and leakage current not only for batteries and powertrains, which use a large amount of power, but also for devices such as ECUs and electrical accessories.

Stable Logging - Even at High Voltages and Frequencies. Minimize the Effects of Noise.

The LR8450 reduces the effects of noise to deliver stable logging, even at high voltages and frequencies.
Legacy data loggers could not log temperature accurately in noisy environments due to the effects of high frequencies, which caused values to shift or fluctuate significantly.
The new Hioki Memory HiLogger LR8450 uses a revamped design to dramatically reduce the effects of high-frequency noise, and is ideal for temperature logging of inverters and batteries.

Connect strain gages directly and make measurements in as little as 1 ms.

The Memory HiLogger LR8450 is a data logger that can measure stress via directly connected strain gages. Capable of recording at frequencies on the order of dozens of hertz thanks to sampling at up to 1 ms, the LR8450 is ideal for measuring stress and load on moving parts and strain on components such as brakes and pipes. And because it can accommodate a mix of various measurement modules, the LR8450 can simultaneously measure strain, temperature, and voltage as necessary.

Add a total of up to 7 wireless modules for a maximum of 330 channels

With four U8552 VOLTAGE/TEMP Units and seven LR8532 WIRELESS VOLTAGE/TEMP Units, you can measure a total of 330 channels.

Analog 600 CH Synchronous Sampling Measurement [Since V2.10]

Synchronized sampling up to 5 plug-in modules (600 analog channels) can be measured when multiple LR8450's external sync terminals (SYNC.IN, SYNC.OUT) are connected.

Note: This function cannot be used when wireless modules are connected.

Sample output from a variety of sensors, including 1 ms pressure sensors

Measures at a sampling rate of up to 1 ms.
1 ms sampling rate is the best match to measure sensor outputs with a frequency response of under 100 Hz, for example pressure and vibration sensors.

Measure strain with a 1 ms sampling rate

Connect strain gauges directly and measure at a sampling rate of up to 1 ms.
Strain gauges tend to have long, thin wires that are easily broken, but that potential pitfall can be avoided by using wireless modules so that wire length is minimized.

Measure temperature near an inverter or battery

Measures at a sampling rate of up to 10 ms.

Make measurements in locations where it would be difficult to route wires

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

Battery EV thermal management by measuring temperature and heat flow

Heat flow can be measured by combining the LR8450 with the FHF05 Heat Flux Sensor. Since these sensors allow both temperature and the direction of heat movement to be confirmed, they are useful when validating thermal management.
