A sensor with high-precision, redundant current measurement for consistently efficient energy control.

You're looking for a redundant current measurement system for batteries in alternative drive concepts. It should enable you a safer measurement even in the event when one channel drops out. You prefer a single and reliable user-friendly application and that's what the ICB-M offers you today.

    Isabellenhütte presents a new current measurement system with two independent channels

  • The new ICB-M features two mutually independent measurement channels, which are galvanically isolated and have a separate power supply, setting it apart from the competition. The first channel, a high-precision current sensor, ensures high measurement accuracy through direct shunt-based measurement. The measurement values are determined within a 24-bit range. The current sensor features an output rate of 1 kHz. CAN 2.0 is used for communication, with a data rate of up to 1 Mbit/s. A CAN Database Container (DBC) facilitates rapid system integration. The ICB-M provides a digital measurement channel (Channel 1) as well as an analogue Channel 2, completely galvanic isolated from the first, that relies on a magnetic measurement method and analyses the magnetic field generated by the current flow in the conductor, providing a voltage-level output in a measurement range of +/- 300 amperes.

  • Redundancy means certainty and cost-benefit advantages

  • The ICB-M makes current measurement safer, even in the event of malfunction. The two measurement channels provide redundancy in the system – the variable to be measured can be calculated in different ways. When one channel drops out, the missing measurement value can still be ascertained with the alternative channel. “The ICB-M makes a higher level of safety possible than conventional current measurement modules. A downstream integrated safety functionality makes it possible to achieve ASIL C,” according to Jens Hartmann, Sales Director ISAscale® at Isabellenhütte. The redundancy enables on-board diagnostics (OBD) and also has cost benefits versus selective solutions. A second measurement system must be integrated to ensure that conventional sensor modules have room for error. But the affordable ICB-M comes with this included, eliminating the cost of an additional measurement system to ensure redundancy.

  • Read your sensing elements directly by using the Smartec UTI

    The Universal Transducer Interface (UTI) is a complete analogue front end for low frequency measurement applications, based on a self-calibrating period-modulated oscillator. Sensing elements can be directly connected to the UTI without the need for extra electronics. Only a single reference element, of the same kind as the sensor, is required. The output is digital and can communicate with any type of micro-controller.

    The UTI provides interfacing for all kind of resistive and capacitive sensors.

  • Current and voltage measurement in and around hybrid and electric drives

    No matter if you're designing a hybrid, electric or fuel cell powered application - a new development's sustainability always depends on the reliability in every-day use and therefore on controlling its energy flow and consumption permanently. Not every method for measuring current and voltage is able to fulfill each of the difficult requirements. Isabellenhütte has developed the current and voltage measuring module IVT for DC applications in alternative drive concepts based on its experience in the area of car battery management.
