Overview

For laboratory or embedded applications requiring accurate measurement of DC, pulsed DC, or AC current, the Vektrex Hall-effect current sensors provide high-bandwidth current sensing with an amplified 50-ohm voltage output that can be connected directly to an oscilloscope or data acquisition system. Vektrex current sensors are magnetically isolated like clamp-on oscilloscope probes, they are 5X to 10X less costly, and they provide for secure cable attachment.

Eliminates Shunt Resistor Errors

Shunt measurements produce very small amplitude signals that are subject to noise and parasitic effects that reduce the measurement accuracy and distort the frequency response. The result is often poor rise time, extra overshoot and extra undershoot. Shunts are also problematic to use when measuring high-side currents, as a differential amplifier must remove the high-side voltage before a safe measurement can be made. Vektrex current sensors eliminate shunt resistor errors, producing an accurate representation of the current signal.

"Yesterday I tried it to diagnose a problem on a stack life test rack. One of the difficulties with a laser stack (multiple bars) is that the voltage is much higher (4 to 32 volts) and the pulsed current is very high as well (up to 300 amps). A regular shunt has too much influence on the circuit...and high voltage probes across the device don't work so well. It worked great!"
