1 ms Sampling Portable Logger Expandable to 120 Channels with Your Choice of Plug-in 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 offers 1 ms sampling across up to 120 channels, and can be paired with 5 different types of plug-in input units. New input modules measure strain and distortion, ideal for automotive applications involving the evaluation of vehicle components as well as robotic equipment.
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.
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.
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.
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.
Example: strain measurement
Use model Strain Unit U8554
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 units so that wire length is minimized.
Example: temperature measurement
Use models:
Voltage/Temp Unit U8550
Universal Unit U8551
Measures at a sampling rate of up to 10 ms.
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.
Efficient measurement operations can be achieved by utilizing HIOKI's GENNECT One and GENNECT Cloud.
GENNECT One is a free Windows application that provides central management of multiple instruments on a LAN.
By logging in to GENNECT Cloud from GENNECT One, you can move beyond your LAN and connect to instruments in remote locations.
