The Current sensor BT21i is a general-purpose sensor to measure currents in the range between -5 and 5 A. It has two 4-mm plugs for easy connection. The sensing element is a 0.04 Ω resistor connected between the red and black terminals.
Range: -5 … +5 A
Resolution (12-bit): 3.8 mA
Can be used to:
• investigate relationships between voltage and current,
• verify Ohm’s law,
• measure currents in series and parallel electrical circuits.
