GENEVA, Switzerland and MILWAUKEE, WI (December 19, 2006) − LEM S.A., the world’s leading manufacturer of isolated current and voltage measurement components, today introduced its HAB family of current sensors for automotive battery-monitoring applications. The 12 sensors in the family offer primary current measurement ranges from ±20 to ±120A, a high accuracy of ±2% across the operating temperature range of -40 to +125˚C and a choice of voltage or PWM outputs.
The sensors are based on open-loop, Hall-effect transducers that simplify both installation and servicing by removing the need to cut the cable carrying the measured current. They operate from a unipolar 5V supply and provide a fully ratio metric solution for the voltage output devices. Response time is less than 10ms.
A watertight housing and sealed connector provide full environmental protection in under-the-hood applications.
Principal applications are expected to be in the measurement of battery-pack current in electric, hybrid and conventional vehicles.
