Product Description

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 offers a sampling speed of up to 1 ms and up to 120 channels, depending on the types of plug-in modules that are selected. The modules measure strain and distortion, ideal for automotive applications involving the evaluation of vehicle components as well as robotic equipment.

- Expandable to 120 ch with wired/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

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.

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.

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 units, the LR8450 can simultaneously measure strain, temperature, and voltage as necessary.

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

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 Use model High Speed Voltage Unit U8553
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.

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.
