Hioki Launches Memory HiLogger LR8450/LR8450-01
Hioki LR8450 Memory HiLogger
330-Channel Portable Logger Delivers 1 Ms Sampling, Even Over Wireless Connections, Available with Your Choice of Plug-In and Wireless Units
December 9, 2019 - Nagano, Japan
Hioki is pleased to announce the launch of the Memory HiLogger LR8450 and LR8450-01.
■ DEVELOPMENT BACKGROUND
Customers in the automotive and environment/alternative energy sectors, both of which Hioki has identified as priority markets, have embraced the legacy Memory HiLogger LR8400 series (max. 10 ms sampling), which can measure a large number of channels despite its compact size, and the popular Wireless Logging Station LR8410 (max. 100 ms sampling), which separates data measurement (by units) and collection (by the instrument).
Common themes appearing in feedback from LR8400 and LR8410 users included a desire to measure large numbers of channels more quickly in development of products such as electric vehicles (EVs), to measure strain on vehicle chassis and batteries along with temperature, and to reduce wiring man-hours and measurement issues by capturing strain data wirelessly.
■ KEY FEATURES
1. Sample a Large Number of Wired and Wireless Channels at Up to 1 ms
Customers need measurement solutions that are capable of accommodating abrupt changes in load in the development of electric vehicles such as EVs, hybrids (HVs), and plug-in hybrids (PHVs). By using the High Speed Voltage Unit U8553, a 5-channel plug-in unit that can measure voltage at a sampling rate of 1 ms, customers can capture such rapid changes.
The LR8450 series is ideal for capturing output data from sensors that measure low-frequency (from 10 to several dozens of hertz) data such as resin pressure or vibration, which are difficult to measure at conventional sampling speeds. The Wireless High Speed Voltage Unit LR8533, a 5-channel wireless unit, can measure voltage at a sampling rate of 1 ms. This sampling rate is 100 times faster than the LR8410 Wireless Logging Station.
2. A Single Solution for Dynamic Strain Measurement
The Strain Unit U8554 (a plug-in unit) and the Wireless Strain Unit LR8534 (a wireless unit) are also capable of sampling data at up to 1 ms, making them useful in testing strain on vehicle chassis and brakes.
3. Add Wired or Wireless Channels as You Need Them
• Testing of automobiles, farm and construction machinery, and electric devices
• Embedding in preventive maintenance systems for production equipment and evaluation equipment at manufacturing plants
■ SERIES LINEUP
Memory HiLogger LR8450 (standard model)
Memory HiLogger LR8450-01 (wireless LAN model)
Voltage/Temp Unit U8550 (15 channels, plug-in)
Wireless Voltage/Temp Unit LR8530 (15 channels, wireless)
*Example units shown (a total of five plug-in and five wireless units are available).
*Hioki plans to launch all wireless units in 2020.
*1 Strain: The ratio of the change in the form of elongation and contraction that occurs in an object when a force is applied. The minuscule change in electrical resistance caused by strain is detected and measured using a strain gauge.
*2 If four Voltage/Temp Unit U8552 (30 channels, plug-in) units and seven Wireless Voltage/Temp Unit LR8532 (30 channels, wireless) units are connected, the LR8450-01 can measure 330 channels of voltage and temperature data at a maximum sampling rate of 20 ms.
*3 Strain gauge: A sensor for measuring strain.
