BATTERY CELL SIMULATOR 2500

The All-in-One module 2511 is predestined for use in automated manufacturing testing of high-performance battery modules and battery packs, regardless of whether they are round, prismatic or pouch cells. In single or multichannel mode, important battery parameters such as AC and DC internal resistance or cell voltage can be recorded and evaluated extremely fast and precisely using fieldbus-capable technology in order to make quality-relevant statements regarding ageing .............. FEATURES AC and DC internal resistance measurement 10 … 300 mΩ Four-wire measurement method for highest precision Measuring and evaluation results in a few milliseconds Frequency ranges: 1kHz, 100 Hz, 10 Hz, 1 Hz Voltage measurement: 0 ... ±5 VDC/±60 VDC Temperature measurement: 0 °C … +100 °C Resolution: up to 0.01 μΩ Single to multi-channel applications, temperature measurement Extremely compact design, state-of-the-art interfaces PC software for intuitive parametrisation and configuration

The RESISTOMAT® model 2311 has been designed and optimized for high-speed applications in automation systems. Up to 100 measurements per second can be achieved. It works on the basis of the welltried four-wire measurement method in which test-lead resistances and contact resistances are eliminated. The instrument leads are monitored for damage by a built-in open circuit detector. A 2-way and 4-way comparator with switching outputs is available for classifications and selections. Of course, temperature compensation is available for any test object material. Specific temperature coefficients can be entered. Temperature recording takes place using a PT100 sensor or a temperature transmitter (pyrometer) with an analog output. A special circuit for protecting the measurement input when measuring inductive test objects has been developed to prevent damage to the meter from voltage peaks produced when the test object is disconnected.

The DIGIFORCE® 9307 monitors processes in which precisely defined functional relationships between two or more measured quantities need to be demonstrated. These measured quantities are recorded synchronously during the manufacturing process or subsequent functional testing to produce a measurement curve, which is then assessed using graphical and mathematical evaluation techniques. After internal evaluation, the measurement curve and computed evaluation results are visualized on the color display and are also output at the external control interfaces. The processes in the controller are optimized by a powerful real-time operating system to achieve an extremely fast evaluation cycle: it typically takes just 15 ms to deliver the global OK or NOK evaluation result, which can then be analyzed by the higher-level controller.

Model 9180 supports force, pressure and torque sensors operating on the strain gauge principle, as well as the connection of position and angle sensors in potentiometer or DC/DC configuration. It also allows the measurement of process signals ± 1 V/ 5 V/ 10 V or 0 ...1 mA, 0(4) ... 20 mA. The current measured value is indicated on the 14 mm high LED main display, while a second display located directly below provides a reading of the peak value. The display is particularly suitable for highly accurate measurements due to the high accuracy of 0.1%. It is also possible to monitor up to 4 limit values and provide the results via relay or transistor outputs. Thus the process value display can be used for classification, process and control tasks. The current measured value is frozen on the display by activating an external HOLD signal. The TARE function is useful for balancing out previous loads for example.
