High current Hall effect sensors
June 2013
Electrical Power & Protection
The CTL/CTA range of Hall effect DC current transducers is available in current ranges up to 40 kA. The illustration shows a 30 kA unit with split core for easy installation over busbars up to 330 x 330 mm. When combined with a signal conditioner Model CTA, provision can be made for outputs of ±10 V, 4-20 mA, ±5 V or ±1 mA. Accuracy is 1% at full scale and can be used at temperatures up to 65°C.
Typical applications include DC arc furnaces, chlorine production and electro-winning of copper, zinc and platinum i.e. all electro-chemical and electro-metallurgical processes.
