Description
Infrastructure such as electric power facilities, data center UPSs, and railroads must operate with stability and zero downtime. High-precision waveform recording with the Memory HiCorder is essential to ensure safe and reliable operation of critical infrastructure.
Sturdy High-Speed DAQ System
The Memory HiCorder MR8848 is a recording device used in fields such as power plants, railways, and industrial plants to measure transient phenomena.
The robust housing design has passed rigorous tests such as drop tests and vibration tests.
With high-speed sampling that captures the voltage and current waveforms of inverters, large-capacity memory that stores entire events, and multi-channel measurements that allow for the verification of correlations between multiple signals, it ensures that you won't miss critical waveforms.
Key Features
- Work anywhere with a durable, shock-resistant, portable design
- Safely measure with isolated channels
- Handle complex tasks using 32 analog & 64 logic channels
- Record for extended periods with high-capacity memory
- Make pass/fail judgments with waveform & numerical analysis
- Check printed waveforms on-site using a built-in printer (optional)
Note: MR8848 cannot operate alone. You need to purchase and install one or more optional input modules, etc.
For Evaluation Testing and Troubleshooting
Robust Housing
To minimize the risk of failure due to drops and shocks, the Memory HiCorder MR8848 employs a rugged housing with protectors for enhanced durability.
Safe and Reliable Measurements
When inspecting lines of differing electrical systems simultaneously (e.g., power lines and signals), short-circuit are a serious risk. Unlike oscilloscopes, memory HiCorders have isolated channels, so short-circuit accidents will not occur between differing circuits.
Correlation Analysis of Various Physical Phenomena
Troubleshooting and analysis can be more in depth than ever before through simultaneous recording of various physical phenomena.
The Memory HiCorder MR8848 records and analyzes multiple physical parameters—including voltage, current, temperature, vibration, pressure, and strain—for identifying correlations and root causes.
Onsite, Tamper-Proof Printing (Factory-Installed Option)
The factory-option printer lets you immediately print and share tamper-proof hard copies of your measurements right at the site, so that data cannot be tempered with.
Record Long-Duration Waveforms with High-Capacity Storage
Long-term waveform recording becomes possible by storing data on the large-capacity 1 TB SSD (U8334) with the Direct Write to Storage option (MR9001-01).
For example, in railway vehicle measurement, the Memory HiCorder will record over 10 parameters at a sampling rate of 10 µs/S for more than an hour.
