Sensor-Technik Wiedemann (STW), based in Kaufbeuren, and Isabellenhütte Heusler from Dillenburg have joined forces to develop a battery management solution for utility vehicles featuring hybrid drive technology. The two firms have now signed a co-operation agreement that will pave the way for further joint efforts in development and production of key components for electric drives.

Isabellenhütte Heusler GmbH & Co. KG, one of the world’s leading manufacturers of Alloys for Thermocouples and Resistance Alloys as well as Alloys for Low-Impedance Precision and Power Resistors, has appointed Jürgen Brust as new Managing Director. On July 1, 2009, the 52-year old joined Managing Director Peter Müller on the management board as head of Research and Development and Production for the aforementioned business areas including th...

Isabellenhütte, Semikron and Siemens Drive Technologies have cooperated to develop a 3 phase shunt module for the Siemens SINAMICS G120 frequency inverter series. This series is intended for measuring phase currents of up to 20 A through shunts on the circuit board. Apart from this, currents of up to 400 A can be measured with outstanding precision and long-term stability using the jointly developed shunt modules in Semikron’s Semitrans housin...

Lithium-ion battery charging and discharging periods pose a great challenge for current and voltage measurement. At electronica, Isabellenhütte Heusler is presenting a sensor module (IMC) tailored to these needs. It can be completely configured according to customer requirements.

Isabellenhütte’s IMC and IMS sensor modules have been developed for all areas of use in which large currents, voltages and temperatures have to be measured with high precision.

The European Columbus laboratory is now in space, and precision resistors from the Isabellenhütte SMx series are on board. It is by no means easy to fulfil the stringent requirements set by aerospace and space organisations. Components must function reliably even when subjected to extreme influences. For example, the SMx series resistors for use in space can endure the vibrations which occur when the shuttle lifts off, remain undamaged in condit...
