MEASTEK HCTM030KA High Sensitivity High Frequency Flexible Current
Probe 5mV Vpp Low Noise For Large Current Measurement
Ultra-large range and high-precision measurement
With a sensitivity of 0.2mV/A, it can accurately measure peak
currents up to 30KA, meeting your stringent requirements for
ultra-large range and high-precision current measurement. It is a
powerful assistant in the fields of high-voltage power
transmission, large-scale industrial manufacturing, etc.
Extremely low noise interference
The maximum noise is 5mV Vpp, which effectively reduces the noise
interference during the measurement process. Even in a complex
electromagnetic environment, it can provide you with pure and
accurate current measurement results, allowing you to have a clear
and accurate understanding of the current status of the device.
Stable and reliable attenuation performance
The attenuation characteristic is 0.1%/ms, which ensures the
stability and reliability of the measurement data. In long-term and
high-demand measurement tasks, it can effectively reduce the errors
caused by signal attenuation and provide you with reliable
long-term monitoring data.
Advantages of high-frequency and large current measurement
The high-frequency bandwidth -3dB is 15MHz. For some ultra-large
current signals with high-frequency components, such as
high-frequency currents in large power electronic devices, it can
accurately measure and meet your needs for complex current signal
analysis.
Application scenarios
high-voltage transmission line substation, monitoring bus current;
current detection of collector lines in large wind farms; current
measurement of auxiliary equipment in nuclear fusion experimental
devices.
