Sensor Modules for direct measurement of current, voltage and temperature

The calibrated IMC sensor module (IMC-A-R001) is designed for 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. In the latter case, it is especially suitable for lithium-ion batteries. The current measurement is performed via a 100 µOhm shunt. The Isabellenhütte’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.

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 µOhm shunt. The Isabellenhütte’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. In contrast to conventional current measurement systems, the specified precision can also be attained taking account of all conditions such as linearity errors, offsets and temperature effects.

The scope of implementation is wide: 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.
