Optimizing the energy efficiency of electrical systems is an ongoing challenge. For this purpose, Hioki has developed an innovative multi-channel current measurement solution specifically for development teams in the electrical and e-mobility industry. For the first time, even the smallest currents can be individually measured and recorded thanks to ultra-compact yet high-precision current sensors.

Precise measurement of all power consumers in an electrical system requires high-precision sensors. Hioki's new AC/DC zero-flux current sensors allow development engineers to measure from 100 µA to 2 A with the CT7812 and 100 mA to 20 A with the CT7822, with an impressive accuracy of ±0.3 percent.

With this high precision, combined with a minimal resolution of 0.1 mA, development teams can now obtain very accurate consumption data even at low currents. These insights enable targeted improvements in the energy consumption of systems, significantly extending the operating times or ranges of electric vehicles.

Ultra-compact zero-flux current sensors for confined spaces

The new current sensors also impress with their ultra-compact design. With an overall length of only 7.65 cm and a practical sliding mechanism, the particularly small current sensors can be effortlessly connected to all power consumers. Even in confined environments such as engine compartments, housings, or control cabinets, they can be conveniently installed—and work reliably even under significant temperature changes.

Reliable long-term recording

A data logger captures measurement values over longer periods. It is therefore crucial that the sensors used do not display drift. Hioki sensors with fluxgate technology offer developers reliable temperature compensation in this context. In a temperature range from -40 to +185 degrees Fahrenheit, stable measurement results are ensured even during long-term measurements under significantly varying temperature conditions.

Effective recording of currents with up to 55 channels

For an effective and accurate mapping of a system's current flows, the data logger LR8450-01 with the two new modules LR8536 and U8556 enables the simultaneous measurement of up to 55 power consumers with a single setup. Additionally, the data logger LR8450-01 allows the recording of other important signals such as temperature, strain, vibration, humidity, resistance, voltage, or CAN signals.

The logger system offers up to 330 analog channels depending on the combination of modules and measurement parameters. This flexibility enables engineers to comprehensively assess electrical systems considering all relevant parameters with just one measurement setup. Additionally, the use of WLAN modules allows for efficient measurement setups with less complex wiring, even in complex electrical systems like electric vehicles, trucks, construction machinery, or agricultural machines.

Now also with Wi-Fi connection

Another highlight of Hioki's new multi-channel current measurement solution is the wireless data transfer via WLAN. The LR8450-01 is thus the first data logger that allows spatial separation of the current sensors and modules from the data logger. This saves setup time and offers development teams more flexibility in setup, enabling quicker assessment of the energy efficiency of electrical systems, especially in electromobility. With wireless measurement modules and the newly added current measurement function, the LR8450-01 is one of the most versatile and efficient data acquisition systems for a wide range of industrial applications.
