Current Sensor from Pacific Scientific OECO

The F.W. Bell CS20 Series Hall effect current sensor from Pacific Scientific OECO, Milwaukie, OR, is designed to improve the performance of solar energy support products. The 1.4 in. by 0.091 in. by 0.472 in. device is a bipolar current sensor with a linear ±15 A measuring range, a bandwidth up to 50 kHz, quiescent current of 2.5 V, bipolar current hysteresis <0.5%, and the ability to lower the bandwidth to match sampling rates by adding an external capacitor. Operating temperature range is –20°C to 85°C.
