For use in high voltage, high current control systems

Precise Sensor Modules for direct measurement of current, voltage and temperature
The automotive industry is facing tremendous challenges as it evolves towards use of new propulsion systems. Among these are hybrids, electric plug-ins, and fuel cells. All of these require reliable, safe, cost-effective energy storage.

Isabellenh�tte's IMC and IMS sensor modules have been developed to meet these needs where large currents, voltages and temperatures have to be measured with high precision.

The IMS sensor module (IMS-B-R001) is also intended for use in larger measurement systems such as current measurement devices or battery management systems. Here too, it has been designed specifically for lithium-ion systems. The current measurement is performed via a 100 �Ohm shunt. The Isabellenh�tte's 16 bit data registration system ISA-ASIC is used to register the measured values. The IMS can perform measurements within a current range up to 1,500 A with a resolution of 50 mA and within a voltage range of ? 30 V with a resolution of 1 mV. This higher precision level, means the designer can account for conditions such as linearity errors, offsets and temperature effects - which conventional current measurement systems cannot achieve.

A second sensor, the IMC module (IMC-A-R001), is designed for a calibrated direct current and voltage measurement via a 3.3 V or 5 V RS 232 interface. The assembly can be used as a component of measurement systems such as current measurement devices, data loggers or battery management systems. For battery management, it is especially suitable for lithium-ion batteries. The current measurement is performed via a 100 �Ohm shunt. The Isabellenh�tte's 16 bit data registration system ISA-ASIC is used to register the measured values. The IMC can perform measurements within a current range of 0 - 1,500 A with a resolution of 50 mA and within a voltage range of ? 20 V with a resolution of 1 mV. Other current ranges can be attained by use of different shunts.

This device family has a broad application range, including alternating current drives, AC/DC power control, rectifiers, power converters, direct and alternating current rectifiers, energy measurement, battery control for hybrid drives and electric vehicles, fuel cell control etc.

Isabellenh�tte Heusler GmbH & Co. KG is one of Germany's leading manufacturers of passive components as well as thermoelectric and resistance alloys and specialist for current sensing products for hybrid and electric vehicles.

Recently, the company has appointed an US Automotive Business Development Manager: Mr. Ralph Sorrentino, who is based in Detroit, Michigan. He is responsible for all business development activities of Isabellenh�tte's automotive products in North America.
