Current sensor (-3..3 A)

The Current sensor ML20f is a general-purpose sensor to measure currents in AC and DC circuits in the range between -3 and +3 A. The sensor is equipped with two 4-mm banana plugs and two additional alligator clips are delivered with the sensor. The Current sensor should be placed in series with the circuit component through which the current will be measured. Currents in either direction can be measured. The Current sensor has a very low resistance so that it introduces as little resistance as possible to the circuit. The sensor is protected such that currents up to 5 A will not damage the sensor, but it should never be used for higher currents.

The Current sensor can be used in various experiments such as:
• Characteristics of a light bulb and a diode.
• Measurements of internal resonance and EMF.
• Measurements in series and parallel electrical circuits.
• Together with a Voltage sensor it can be used to explore the relationship between the current and the voltage in electrical circuits.

The Current sensor ML20f is a digital sensor (on-sensor digital conversion), which gives calibrated values of the measured quantity. This sensor can only be connected to the CMA MoLab interface and not to other CMA interfaces such as VinciLab, CoachLab II+ or EuroLab.

Technical specifications of the sensor are described in its User's guide.
