HIOKI LR8450-01 Memory HiLogger Kit

Description

HIOKI LR8450-01 Memory HiLogger Kit (Wireless LAN Model)

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 1ms 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.

Key Features

• Wireless LAN model expandable to 330ch with wireless and plug-in modules
• Record voltage output from pressure and other sensors with 1ms sampling speed
• Directly connect strain gauge and measure signals in as fast as 1ms intervals
• Significantly reduced effects from noise let you safely measure in high voltage and high frequency areas such as around inverter motors
• Avoid wiring issues by minimizing cable length using wireless modules
• Monitor data captured remotely on PC with wireless LAN technology

Features

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.

Scope 3 emission reduction through recording of current consumption and heat energy loss

To attain Scope 3 (*1) emissions targets and ensure alignment with decarbonization goals, it is important to accurately understand the impact of our products on the environment.
We will offer tips to aid developers striving for Scope 3 compliance, focusing on techniques to pinpoint energy losses in electronic components through current and temperature data acquisition.

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 1ms.

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 1ms, 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 1ms pressure sensors

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

Measure strain with a 1ms sampling rate

Connect strain gauges directly and measure at a sampling rate of up to 1ms.
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 10ms.

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.

Observe data from a remote location using a PC or tablet

By connecting the LR8450-01 to a PC or tablet via a wireless LAN, you can control the instrument remotely using the built-in HTTP server or download data files using the built-in FTP server.
