Innovative resistance measurement technology
DE EN

The RESISTOMAT^® model 2311 is designed and optimised for high-speed applications in automation. Up to 100 measurements per second can be realised. It works according to the proven four-wire measuring method, eliminating lead and contact resistances. The measurement cables are monitored using the integrated cable break detection function.

A 2- and 4-fold comparator with switched outputs is available for classifications and selections. Temperature compensation for any test specimen materials is a matter of course. Specific temperature coefficients can be entered. The temperature is recorded using a PT100 sensor or a temperature transmitter (pyrometer) with analogue output.

A special measuring input protection has been developed for measuring inductive test specimens to prevent voltage peaks from damaging the device when the test specimen is disconnected. A special area of application is the measuring of contact transition resistances (dry circuit measurement), as the load voltage is limited to 20 mV to avoid so-called "fritting" (based on DIN IEC 512).

All device settings can be saved individually in up to 32 measuring programmes. Of course, all device settings can also be made via the Ethernet, USB (standard) or fieldbus interfaces (optional). The integrated data logger can store up to 900 measured values per measuring programme.

TASK

During stator manufacture, the stator wire is crimped into the connecting pin after winding. Crimping can cause wire breakage or the crimping process may not be performed correctly, resulting in a higher resistance. The crimping process requires 100% testing.

SPECIFIC REQUIREMENT

Rapid OK/NOK evaluation of the stator
Simultaneous testing of two separate windings in the stator
High-speed testing of an inductive device

Solution

The RESISTOMAT® 2316 measures the resistance values using the contact pins pressed onto the stator connecting pins, thereby ensuring 100% testing.
The test equipment is controlled via the production plant PLC.

Info: This application can also be solved with the RESISTOMAT® 2311.

Branchen

Electronics / Electr. Engineering

Evaluation of the quality of spot-welded joints based on the contact resistance, for example, between the contact lug and the contact surface of the cell
Connection via PROFINET, EtherCAT and EtherNet/IP supports flexible sequence control and measurement data acquisition

Task

Very high-quality of spot-welded contact lugs is elementary in industrial battery pack or module production. The adherence to important mechanical parameters and also electrical parameters such as extremely low contact resistances are extremely important for ensuring the performance of a battery pack or an entire module. With the aid of the RESISTOMAT^® 2311, precisely these spot welded connections are reliably recorded in the low capacitance range, evaluated within a very short time and transmitted to the control unit via PROFINET.
